A. DEFINITION OF THE REGION BEING PROPOSED FOR NOMINATION AS A UROPEAN<br />

GEOPARK<br />

A.1. NAME OF THE REGION PRPOSED FOR<br />

NOMINATIONS AS A EUROPEAN GEOPARK:<br />

The name that is proposed <strong>for</strong> the site applying to take<br />

part in the EUROPEAN NETWORK of GEOPARK is<br />

“BOGDINSKO-BASKUNCHAKSKY GEOPARK”. The<br />

area lies within the borderline of the present Bogdisko-<br />

B<strong>as</strong>kunchaksky reserve.<br />

A.2. LOCATION<br />

The geopark settles down in the south of Russia in the<br />

western part of Near-C<strong>as</strong>pian lowland on a left bank of<br />

the river of Volga within Ahtubinsky administrative area<br />

of the Astrakhan area.<br />

The geopark territory settles down in 50 kilometres<br />

from an administrative centre of the given territory -<br />

Ахтубинска. In immediate proximity from the given<br />

territory on distance about 12 km settlements the<br />

Verhny , Nigniy Bottom and Srednij B<strong>as</strong>kunchak settle<br />

down.<br />

<strong>Geopark</strong> area it is possible to reach railway and motor<br />

transport. By train it is desirable which settles down in<br />

15 kilometres from geopark will stop at station Verhny<br />

B<strong>as</strong>kunchak, further journey is carried out by motor<br />

transport. For Journey on the car the network of the<br />

highways connecting an connect the Astrakhan and<br />

Volgograd are<strong>as</strong> too can be used <strong>for</strong> journey to<br />

geopark.<br />

The nearest international airports settle down in the<br />

cities of Astrakhans and Volgograd, located within 300<br />

kilometres from geopark territory. This distance can be<br />

overcome by the bus, a train, or the car on it will leave<br />

about 4 hours.<br />

A.3. SURFACE AREA, GEOGRAPHICAL AND<br />

HUMAN STATISTICS<br />

The area is in limits of Bogdinsko-B<strong>as</strong>kunchak<br />

reserve. Its area makes 18478 hectares. The reserve<br />

consists of two sites: Vicinities of salty lake<br />

B<strong>as</strong>kunchak and mountain Big Богдо (16483<br />

hectares) and a site «the Green garden» (2004<br />

hectares). In all territory of geopark the economic<br />

activities are not carried out, the given area is<br />

especially protected territory.<br />

<strong>Geopark</strong> holistic way<br />

Our geopark policy is aimed to create a connection<br />

between man, environment, culture, society and<br />

geology in close agreement with the general<br />

philosophy of the <strong>European</strong> <strong>Geopark</strong>s Network.<br />

The geological diversity found within the geopark<br />

offers great possibilities to demonstrate how geology is<br />

able to influence the bio-diversity, animal breeding,<br />

agriculture, communication and the very important<br />

<strong>as</strong>pects of life and cultural evolution like the human<br />

presence ever since pre-history and proto-history, and<br />

the great epopee during which the exploitation of<br />

gypsum and saltw<strong>as</strong> carried out.<br />

3<br />

Population<br />

The resident population of the District involved is equal<br />

to 73152 in habitants (Istat, 2007). The average<br />

population density is 9.3 inhabitants / sq.km.<br />

In the l<strong>as</strong>t ten years the resident population of the<br />

area, likewise <strong>for</strong> the total province population, h<strong>as</strong><br />

been subject to a decre<strong>as</strong>ing flux. Such trend however<br />

results <strong>as</strong> a contr<strong>as</strong>t, compared to the regional value<br />

which is substantially stable.<br />

B. Bogdo<br />

Tourism<br />

Despite presence of a considerable cultural heritage.<br />

The tourist stream which concerns all area comes to<br />

an end in the digital <strong>for</strong>m bad.<br />

Tourism in territory of Bogdinsko-B<strong>as</strong>kunchak reserve<br />

h<strong>as</strong> the big history and is developing branch. Here in<br />

territory of Bogdinsko-B<strong>as</strong>kunchak reserve there are<br />

the unique objects, capable to draw attention of<br />

tourists. Those are nature sanctuaries: mountain Big<br />

Bogdo, natural oundary a green garden, salty lake<br />

B<strong>as</strong>kunchak and karstic caves in its vicinities.<br />

No other geopark comparable to this in the<br />

<strong>European</strong> <strong>Geopark</strong> Network.<br />

Here there is unique in area денудационная a plain<br />

complicated by various <strong>for</strong>ms of a relief: funnels,<br />

caves, beams which were <strong>for</strong>med throughout many


thousand years. It became possible <strong>as</strong> a result of<br />

many transgressions of the C<strong>as</strong>pian sea which<br />

promoted <strong>for</strong>mation of the salty lake B<strong>as</strong>kunchak<br />

largest in Europe. In territory of geopark it is a lot of<br />

places where ancient adjournment leave on a day<br />

surface, <strong>for</strong>ming unique geological landscapes.<br />

A.4 ORGANIZATION IN CHARGE OF THE<br />

EUROPEAN GEOPARK ZONE<br />

Bogdinsko-B<strong>as</strong>kunchakskiy <strong>Geopark</strong> – A Quality<br />

Rural, Cultural,<br />

Sustainable Tourist District<br />

To resort to an <strong>as</strong>sociative District locally, represents<br />

an attempt to put into a network all those factors<br />

around a good idea <strong>as</strong> a precise, locally integrated,<br />

sustainable development strategy and, at the same<br />

time, the District is the strategic instrument to relaunch<br />

those identity values that can be found within a<br />

territory, <strong>as</strong> an evolved product of the interaction<br />

between natural and cultural factors.<br />

Thus it finds synthesis and development in the geotourism<br />

and <strong>Geopark</strong> idea, <strong>for</strong> the revaluation and thus<br />

the safeguard of the local rural heritage.<br />

The District strategy can have a triple valence:<br />

1.<strong>as</strong> an instrument to program the sustainable<br />

development of the Bogdinsko-B<strong>as</strong>kunchakskiy area,<br />

2.<strong>as</strong> an operational support to reposition that part of<br />

the territory to a ready tourism,<br />

3.<strong>as</strong> a hauling element <strong>for</strong> the area with a<br />

highpotential, but that is not able to take off.<br />

With the creation of the District, it is intended to<br />

revalue and promote in a new way the territory of the<br />

Bogdinsko-B<strong>as</strong>kunchakskiy <strong>Geopark</strong> and its<br />

resources, proposing a geo-tourism development with<br />

a series of “routes” that, at the same time, put in<br />

evidence the natural geologic wine, g<strong>as</strong>tronomy,<br />

tourist and cultural values while creating a coordinated<br />

and quality tourist-reception offer, even in<br />

relation to complementary services.<br />

B. SCIENTIFIC DESCRIPTION OF THE REGION BEING PROPOSED FOR NOMINATION AS A EUROPEAN<br />

GEOPARK<br />

of pl<strong>as</strong>ters кунгурского a circle, hundred is caused by<br />

display hydrochloric тектогенеза. It h<strong>as</strong> defined wide<br />

development here alkali processes and, <strong>as</strong><br />

consequence, specific <strong>for</strong>ms of a relief. In the<br />

tectonic relation the territory represents the<br />

B<strong>as</strong>kunchak hydrochloric file testing a modern<br />

raising, and мульду, filled with lake B<strong>as</strong>kunchak. In<br />

the l<strong>as</strong>t of 15-20 thousand years the site tested a<br />

raising with a speed to 0,04-0,06 millimetres a year. It<br />

testifies to high tectonic activity in plat<strong>for</strong>m conditions.<br />

Structural features, history of geological development<br />

and climate have defined a geomorphological<br />

structure of territory. The site денудационной plains<br />

with an absolute mark of 149,6 metres Here settles<br />

down. The plain Denudatsionnaja corresponds to a<br />

hydrochloric file and smoothly p<strong>as</strong>ses in<br />

accumulative which surrounds lake B<strong>as</strong>kunchak.<br />

B.1. DEFINITION OF THE GEOGRAPHIC REGION IN<br />

WHICH THE NOMINATED AREA IS LOCATED<br />

The lake B<strong>as</strong>kunchak and mountain Bolhoe Bogdo are<br />

located in the western part of Near-C<strong>as</strong>pian lowland on<br />

the left co<strong>as</strong>t of the river Volga. The main element of<br />

hydrography in the given area is the salty lake<br />

B<strong>as</strong>kunchak, it in Near-C<strong>as</strong>pian lowland which area<br />

makes of the largest lakes about 12 square kilometres.<br />

It is a large hollow not having a drain, being in the<br />

central part in which flow down superficial waters from<br />

surrounding heights. At lake co<strong>as</strong>t is more than 70<br />

ravines. At e<strong>as</strong>t co<strong>as</strong>t «Gorkaj Rechka» - the largest<br />

source is located. The absolute mark of a surface of<br />

lake B<strong>as</strong>kunchak makes-21,3 metre. The western co<strong>as</strong>t<br />

more abrupt also h<strong>as</strong> developed овражную a part. In<br />

area there are small fresh lakes. They represent falls in<br />

a relief. As a whole vicinities represent hilly plain.<br />

On the character the climate of the given area concerns<br />

a climate of northern desert. In a cold se<strong>as</strong>on<br />

continental polar air which arrives with e<strong>as</strong>t or юго e<strong>as</strong>t<br />

winds here dominates. In the winter these winds cause<br />

cold, and in the spring - droughty hot weather. This air<br />

h<strong>as</strong> small humidity and low temperatures. In a cold<br />

se<strong>as</strong>on intrusion of Arctic dry and cold air which cause<br />

the sharp cold snaps accompanied by a strong wind<br />

from northwest, northern and to northe<strong>as</strong>t directions is<br />

periodically observed.<br />

In summer and autumn months the field of the raised<br />

pressure quite often broken by p<strong>as</strong>sage of cyclones,<br />

moving on average widths is established. At this time<br />

year, <strong>as</strong> well <strong>as</strong> in the winter, prevailing influence<br />

remains behind continental polar air which happens dry<br />

enough and прогретым, arriving here with northern,<br />

northe<strong>as</strong>t and e<strong>as</strong>t winds.<br />

Considerable deposits are observed seldom and<br />

b<strong>as</strong>ically are connected with an exit of southern<br />

cyclones.<br />

Air temperature h<strong>as</strong> sharply expressed annual course.<br />

The coldest months in this territory are February and<br />

January. Average monthly temperatures of air almost<br />

identical also make 8,6 and 8,5 degrees of Celsius of a<br />

frost.<br />

The average annual temperature of air is equal 8,2<br />

degrees of Celsius. Высокте summer temperatures of<br />

air are combined with sharp changes of temperatures<br />

of day and night, and <strong>as</strong> in low temperatures of winter<br />

During большей parts of year prevail northe<strong>as</strong>t and<br />

e<strong>as</strong>t winds, reaching a maximum in a cold se<strong>as</strong>on. In<br />

November, December, January winds e<strong>as</strong>t, from<br />

February till May - northe<strong>as</strong>t prevail.<br />

Within a year deposits drop out non-uni<strong>for</strong>mly. The<br />

greatest quantity of deposits drops out in December -<br />

26,5 mm, the le<strong>as</strong>t - in February - 18,3 mm.<br />

B.2. GENERAL GEOLOGICAL DESCRIPTION<br />

In the modern geological plan the area represents the<br />

arch of the large B<strong>as</strong>kunchak hydrochloric file<br />

surrounded межкуполными with hollows. Feature of a<br />

geological structure is presence near to a day surface<br />

5<br />

Bolshoe Bogdo mountain<br />

B. 2.1. Plain Denudatsionnaja.<br />

The plain Denudatsionnaja occupies a considerable<br />

part of territory round lake. Its absolute marks go<br />

down from periphery in a direction to lake from 19,7<br />

metres to 0 metres. During the period<br />

раннехвалынской transgressions all territory h<strong>as</strong><br />

been covered by the sea. Only the mountain Bolhoe<br />

Bogdo with an absolute mark of 49-50 metres<br />

towered in the <strong>for</strong>m of island.<br />

B. 2. 2. Karstic processes in lake B<strong>as</strong>kunchak<br />

vicinities<br />

Karstic <strong>for</strong>ms of a relief around lake B<strong>as</strong>kunchak are<br />

caused by an exit on a day surface осадочных<br />

breeds old paleozoic the age, presented ander perm


pl<strong>as</strong>ters kungurian a circle. Pl<strong>as</strong>ters are lifted on a day<br />

surface owing to hydrochloric tectonics and make the<br />

top part Hydrochloric dome a file in which modern<br />

karstic processes intensively proceed.<br />

B 2.3. Bolshoe Bogdo mountain<br />

The height above the sea level is 149,6m. It is the<br />

highest point of Pric<strong>as</strong>pian lowland.<br />

Flank processes are observed on the most raised<br />

sections, especially in the area of Bolshoye Bogdo.<br />

Under the action of temporarily arising trickles,<br />

gravitational <strong>for</strong>ces, wind the drift of superficial rocks<br />

and <strong>for</strong>mation of delluvial aprons with the capacity up to<br />

10-15m occurs.<br />

Thus, on hollows of a drain and gullies the drift of rocks<br />

with denudation plains onto accumulative ones and<br />

directly into the lake B<strong>as</strong>kunchack occurs. As a result of<br />

Khvalynian sediments more ancient rocks frequently<br />

submitted by gypsums drift onto the surface of the<br />

mountain.<br />

The lake B<strong>as</strong>kunchack<br />

B 2.4. Forms of rocks eolation on rocky<br />

sedimentations in near vicinities of Bolshoye<br />

Bogdo and « Singing rocks»<br />

In conditions of arid climate physical eolation and eolian<br />

processes are actively shown that results the <strong>for</strong>mation<br />

of outliers of destruction, cellular <strong>for</strong>ms. In separate<br />

places dense rocks collapse even up to sandy<br />

sediments. Wind makes deflation, corrosion, it sorts<br />

sand, carries out finer particles far beyond their initial<br />

distribution.<br />

B 2.5. The lake B<strong>as</strong>kunchack<br />

B<strong>as</strong>kunchack is the salty lake having the area about<br />

115 km ². It is situated in the area of Ahtubinsk<br />

(Astrakhan region), geographical coordinates: 48°10’<br />

northern latitude, 46°53’ e<strong>as</strong>tern longitude/48,166667°<br />

northern latitude, 46,883333° e<strong>as</strong>tern longitude,<br />

approximately in 270km to the north from the C<strong>as</strong>pian<br />

sea, and in 53 km to the e<strong>as</strong>t from Volga.<br />

Shore line in the lake is 21m below the sea level. Water<br />

in the lake is replenished with a help of the small river<br />

Gorkaya, area of a reservoir of which is 11000 km ²,<br />

and with a help of 25 springs. Salinity of the lake is<br />

about 300 gram per litre. Capacity of salt superficial<br />

deposits in the lake is 10-18 m. As a result of salt<br />

6<br />

extraction craters with the depth up to 8 meters were<br />

<strong>for</strong>med. The depth of salt bedding is 6 km. In spring<br />

and in autumn the level of brine in the lake is<br />

maximal - up to 1 meter. In brine bacteria which bear<br />

salt live only.<br />

Since VIII century salt w<strong>as</strong> extracted from the lake<br />

and sent along a Silky way.<br />

For the first time the lake B<strong>as</strong>kunchack is officially<br />

mentioned in 1627 in « The Book of Big Drawing »,<br />

the first geographical description of Russia <strong>as</strong> a<br />

place, « where people extract salt pure <strong>as</strong> ice ».<br />

Today extremely pure salt of lake (99.8 % NaCl)<br />

<strong>for</strong>ms up to 80 % from the general extraction of salt in<br />

Russia. Depending on need, from 1,5 up to 5 million<br />

tons of salt in a year are extracted here. For export of<br />

salt the B<strong>as</strong>kunchack railway w<strong>as</strong> constructed.<br />

At the lake co<strong>as</strong>t there are deposits of medical caolin.<br />

B 2.6. The hole Sharbulack<br />

The section is situated on the southern co<strong>as</strong>t of the<br />

lake B<strong>as</strong>kunchack, to the e<strong>as</strong>t of mountain Bolshoye<br />

Bogdo. It is characterized by the presence of various<br />

<strong>for</strong>ms of the karstic phenomena: caves, craters,<br />

gaps, gullies, cracks, etc.<br />

B 2.7. Karstic <strong>for</strong>ms of relief<br />

The karst in the area of B<strong>as</strong>kunchack is caused by an<br />

output of sedimentary rocks позднепалеозойского<br />

age, submitted by bottom Permian gypsums of the<br />

Kungurianstage, onto the earth surface. Gypsums<br />

are lifted on a day time surface owing to hydrochloric<br />

tectonics; they represent the top part of the salt<br />

cupola m<strong>as</strong>sive in which present karstic processes<br />

intensively proceed.


Karstic gypsums border a bowl of the lake<br />

B<strong>as</strong>kunchack non-uni<strong>for</strong>mly. I.V.Golovachyov offered<br />

the following allocation of karstic fields. Northern field<br />

surrounds a bowl of B<strong>as</strong>kunchack from the west, the<br />

north and the northe<strong>as</strong>t. It is conditionally shared into<br />

three parts: western – from the gully Belaya (Ak -<br />

Dzhar) to the south and west in borders of Kungurian<br />

gypsums extension; northern (or central) field extends<br />

from the gully Belaya to the e<strong>as</strong>t up to the lake Kar<strong>as</strong>un<br />

and to the north up to the lake Turgaj; the e<strong>as</strong>t field<br />

extends to the northe<strong>as</strong>t co<strong>as</strong>t of the lake B<strong>as</strong>kunchack<br />

between the river Gorkaya and the lake Kar<strong>as</strong>un. The<br />

e<strong>as</strong>t field is bordered from the northern field by the river<br />

Gorkaya and also l<strong>as</strong>ts to the e<strong>as</strong>t in borders of<br />

Kungurian gypsums extension. It consists of two<br />

detached closely spaced sections: Vac - Tausk and<br />

T<strong>as</strong>bulack. The southern field is located on the<br />

southern co<strong>as</strong>t of B<strong>as</strong>kunchack, to the e<strong>as</strong>t of Bolshoye<br />

Bogdo. Except <strong>for</strong> these three karstic fields the karstic<br />

removed and detached Cub- Тausk section is allocated.<br />

In the territory of the lake B<strong>as</strong>kunchack vicinities there<br />

are following <strong>for</strong>ms of a karstic relief:<br />

1. The negative superficial <strong>for</strong>ms of the given area<br />

karstic relief are: corries, craters, hollows, gullies.<br />

2. Gypsum hills with the height of up to 4,0 - 6,0m.,<br />

extended from the northe<strong>as</strong>t to the southwest on the<br />

northern and the northe<strong>as</strong>t co<strong>as</strong>t of the lake<br />

B<strong>as</strong>kunchack.<br />

3. Grottoes, niches, shelters (Transitive <strong>for</strong>ms from<br />

superficial karstic <strong>for</strong>ms to underground ones). On the<br />

researched area, within the limits of the northern<br />

gypsum field there are three grottoes: "Lisiy",<br />

"Koljuchiy" and "Sharovskoy".<br />

4. To underground karstic relief in the given area the<br />

following <strong>for</strong>ms can be concerned: karst cracks, karstic<br />

wells and caves.<br />

7<br />

Karst cracks are the most typical <strong>for</strong> the natural<br />

boundary Sharbulack on the southern gypsum field,<br />

and also <strong>for</strong> the central part of the northern gypsum<br />

field. Tectonic cracks (<strong>for</strong>med owing to salt domn<br />

tectonics) are poorly treated by karstic processes.<br />

Mainly they are strongly attached to the raised<br />

sections raised and gypsum hills. The width of<br />

cracks, <strong>as</strong> a rule, is not great (up to 0,4 - 0,6m.).<br />

They have the depth up to 4,0 - 6,0m., and even<br />

more. So, the disconnected crack «Grelka", h<strong>as</strong> the<br />

depth up to 12,5m. Bottoms of cracks are usually<br />

filled by detrital gypsums and friable alluvial sandy<br />

material.<br />

Karst wells. To karstic wells, the vertical cavities<br />

connected to the zone of vertical descending<br />

circulation of karstic waters concern. Depth of wells is<br />

up to 20,0m. Wells of the given area have a<br />

corrosion-erosive origin. They can be fragments of<br />

buried cavities, or the expanded channels of well -<br />

imaginative swallow holes. Wells are available in the<br />

central part of the northern gypsum field. Depth of<br />

them, <strong>as</strong> a rule, is not great - about 4,0 - 6,0m, width<br />

is about 1,0 - 2,0m, cross section is roundish. On<br />

subsurfaces channel corries can be met.<br />

B 2.8. Caves of corrosion – erosion type<br />

Cave Sharbulack.<br />

The entrance is situated in the natural hole<br />

Sharbulack, in the edge of karst-erosive hollow; it<br />

opens with a small descending window. The cave<br />

represents a twisting horizontal tailrace channel<br />

underrated in the distant part. The height of the<br />

entrance reaches 1,5m. The extension of the cave is<br />

about 40m. The maximal depth of the cave bedding<br />

from the steppe level is about 30m. In 2007 owing to<br />

entrance failure the cave became inaccessible <strong>for</strong><br />

visiting.<br />

Cave Grobick. The entrance is situated in the natural<br />

hole Sharbulack in gypsum exposure. The cave<br />

represents a vertical crack with a horizontal bottom.<br />

Between vertical walls in 4,5m above the floor there<br />

is a large wedged gypsum block which teared off the<br />

arch and looks like a coffin. The maximum height of<br />

the entrance is 7,5m. Be<strong>for</strong>e the creation of the state<br />

reserve the cave had been actively visited by tourists.<br />

Cave Cherep. The entrance of the cave is situated in<br />

the natural hole Sharbulack, in a slope of karstic<br />

crater; it is submitted with a small entrance grotto<br />

with a height of 2,5m and width of 3m. In the depth of<br />

the grotto the block with the inscription and the image<br />

of a skull with bones is located. In the beginning of<br />

the l<strong>as</strong>t century the cave w<strong>as</strong> named « Forty doors ».


The cave is situated in gypsum and represents the<br />

large landslide underground hall complicated with large<br />

blocks. Be<strong>for</strong>e the creation of the state reserve it had<br />

been actively visited by tourists.<br />

Cave Natechnaya. This cave is situated in the same<br />

crater <strong>as</strong> Cherep but on the opposite slope. It<br />

represents a large vertical crack (max. height up is to<br />

5m, width is up to 2,5m), with one small entrance -<br />

manhole, decorated with a white gypsum bark of<br />

secondary crystallization. Be<strong>for</strong>e the creation of the<br />

state reserve it had been actively visited by tourists. It<br />

h<strong>as</strong> been known since 1969.<br />

Cave November, 8. It is situated in the natural hale<br />

Sharbulack. It w<strong>as</strong> found in 1985. The entrance to the<br />

cave is located in a slope of karstic crater. The cave<br />

represents a descending crack in gypsum rock.<br />

General extent is about 30m. The depth from the<br />

steppe level is 13,3m.<br />

Cave March, 8. The entrance is the horizontal channel<br />

of roundish section leaving under the b<strong>as</strong>is of a gypsum<br />

exposure in the western slope of karstic crater. Further<br />

the cave runs along cracks deep into the m<strong>as</strong>sive <strong>as</strong> a<br />

narrow horizontal way. It is narrow, difficultly p<strong>as</strong>sable<br />

and short. It is seldom visited. It w<strong>as</strong> found in 1968.<br />

Cave Familnaja. It is located in the natural hole<br />

Sharbulack. It represents a large vertical crack (max.<br />

height up is to 5m, width is up to 2,5m), with one small<br />

entrance - manhole, decorated with a white gypsum<br />

bark of secondary crystallization. The height of the<br />

manhole is about 8m. The extent is about 20m. The<br />

width is 0,6-0,8m. It is very seldom visited. The<br />

entrance is obstructed. The cave is found in 1968.<br />

Cave Vodjanaja - 1. It is located in the natural hole<br />

Sharbulack in the b<strong>as</strong>is of a slope karstic crater. The<br />

extent of the cave is about 10-12m, the width is 1-1,5m<br />

and the height is 2,5m. The cave obliquely runs to the<br />

B<strong>as</strong>kunchack along balks Sinia, Pezchernaja and in the<br />

natural hollow Spher - Bulak.<br />

In a cut three packs are precisely allocated: the bottom<br />

is sulfate - terrigenous, the average is halogen and the<br />

top is sulfate – terrigenous too. Lithologically this pack<br />

is submitted by anhydrites, argillites, sections with<br />

individual prolayers of salt and aleurolites. The capacity<br />

of this pack is 80-150m.<br />

The halogen pack is combined mainly by stone salt,<br />

sulfur, light grey, middling-and large crystal, with<br />

inclusions of anhydrite, separate large units of which<br />

have the extended <strong>for</strong>m and trans<strong>for</strong>mations of<br />

intensively expressed processes of stone salt in post<br />

sedimentational period.<br />

In halogen thickness there are prolayers and lenses of<br />

anhydrites, argillites, less often aleurolites. Argillites are<br />

dark grey, aleurolite with a big maintenance of carbided<br />

B. 4 Geomorphological features<br />

The area of Bogdo and B<strong>as</strong>kunchack occupies the<br />

special position in geological structure. It is located in<br />

the northe<strong>as</strong>t part of the Northwest PriC<strong>as</strong>pian in<br />

vicinities of the lake B<strong>as</strong>kunchack and mountain<br />

Bolshoye Bogdo. The special feature of a geological<br />

structure is the presence near to a day time surface of<br />

gypsums of Kungurian stage that is caused by the<br />

display of hydrochloric tectogenesis. It h<strong>as</strong> defined here<br />

the wide development of leaching processes and, <strong>as</strong> a<br />

result, specific <strong>for</strong>ms of relief (craters, hollows, caves<br />

and others). Authors paid special attention to studying<br />

of these relief <strong>for</strong>ms.<br />

In the tectonic relation the territory represents<br />

Баскунчакский hydrochloric m<strong>as</strong>sive experiencing a<br />

11<br />

modern rising, and mould, filled with the lake<br />

B<strong>as</strong>kunchack. In one of exposures of Ubo hill<br />

(vicinities of the settlement Nizchny B<strong>as</strong>kunchack a<br />

layer of early Khvalynian clay with de<strong>for</strong>mation up to<br />

1-1,5m ) is traced. For the l<strong>as</strong>t 15-20 thousand years<br />

the section h<strong>as</strong> been uplifted with a speed of up to<br />

0,04-0,06mm per year that testifies the high tectonic<br />

activity in plat<strong>for</strong>m conditions.<br />

Structural features, history of geological development<br />

and climate have defined geomorphological structure<br />

of researched area. There is a unique presence in<br />

the Northwest PriC<strong>as</strong>pian of denudation plains with<br />

the absolute mark of 149,6m. The denudation plain<br />

refers to a hydrochloric m<strong>as</strong>sive and smoothly<br />

p<strong>as</strong>ses to accumulative plain, which outlines the lake<br />

B<strong>as</strong>kunchack. The mould is occupied with the lake<br />

and earlier it w<strong>as</strong> considered <strong>as</strong> compensatory one.<br />

But during the l<strong>as</strong>t decade in connection with the<br />

active extraction of salt, the mould bowing is not<br />

compensated by salt accumulating. There<strong>for</strong>e a<br />

surface of salt in the center of lake caves in about a<br />

minus of 21,2 m. in 90th of XX century up to a minus<br />

of 22 m in 2004.<br />

The peneplain occupies a significant part of territory<br />

the around the lake. Absolute marks of it go down<br />

from periphery in the direction of lake from 149,6m.<br />

Prevailing modern relief <strong>for</strong>ming processes are<br />

fluvial, karstic and processes of physical aeration.<br />

As a result of linear erosion hollows of a drain are<br />

<strong>for</strong>med. In total more than 70 hollows run into the<br />

lake.<br />

Other remarkable <strong>for</strong>m of a relief is gullies with the<br />

extent from several up to ten and more meters.<br />

Especially quickly they develop in ruts of roads after<br />

showers.<br />

On flat slopes of low raisings sections of a plane<br />

drain with the area from several square meters up to<br />

several tens square meters are <strong>for</strong>med. On hollows<br />

of a drain and gullies drift of rocks from the peneplain<br />

to accumulative one and directly to the lake<br />

B<strong>as</strong>kunchack occur. As a result Khvalynian<br />

adjournments are drifted and more ancient rocks<br />

frequently submitted by gypsums come onto the<br />

surface.<br />

Special interest is represented by karstic <strong>for</strong>ms of a<br />

relief. The karst area of B<strong>as</strong>kunchack, according to<br />

A.G.Chikisheva and N.A.Gvozdetskogo's<br />

cl<strong>as</strong>sification concerns to PriB<strong>as</strong>kunchack karstic<br />

district of Western - PriC<strong>as</strong>pian karstic province of<br />

PriC<strong>as</strong>pian karstic area of the E<strong>as</strong>t Europe karstic<br />

country.<br />

The karst area of the lake B<strong>as</strong>kunchack is caused by<br />

the exit onto a day time surface of sedimentary rocks<br />

of late Paleozoic age, submitted by late Perm<br />

gypsums of Kungurian stage. Gypsums are lifted<br />

onto a day time surface owing to hydrochloric<br />

tectonics and make the top part of the salt dome<br />

m<strong>as</strong>sive in which modern karstic processes<br />

intensively progress and which is the most accessible<br />

to researches. Karstic gypsums border the bowl of<br />

B<strong>as</strong>kunchack non-uni<strong>for</strong>mly.<br />

Karstic gypsums are strongly dim from a surface and<br />

are blocked by a thin cover of adjournment.


Overlapping rocks are submitted, <strong>as</strong> a rule, by sandy<br />

loams and loams of Khvalynian age. N.A.Gvozdetsky<br />

(1981) refers the karst of this area to the covered type.<br />

At the same time there are also local sections of the<br />

open karst. They b<strong>as</strong>ically are characteristic of large<br />

karstic-erosive hollows of a superficial drain (Belaja,<br />

Pezcherskaja, Sharovskaja) and natural hollow<br />

Sharbulak.<br />

For the area of lake B<strong>as</strong>kunchack G.V.Korotkevich<br />

gives the size of karst <strong>for</strong>ming activity - 3,25mm / year.<br />

The karstic relief of the area of lake vicinities develops<br />

from superficial and underground karstic <strong>for</strong>ms.<br />

To superficial <strong>for</strong>ms of karstic relief on the given area it<br />

is possible to include craters and hollows.<br />

The largest <strong>for</strong>ms of the karstic superficial relief in the<br />

given area are karst-erosive hollows of a superficial<br />

drain. They are developed b<strong>as</strong>ically on the western part<br />

of the northern gypsum field.<br />

To underground <strong>for</strong>ms of a karstic relief in the given<br />

area can be referred karstic wells and caves. To karstic<br />

wells vertical cavities connected to a zone of vertical<br />

descending circulation of karstic waters concern.<br />

The largest karstic cave of PriC<strong>as</strong>pian lowland is<br />

"B<strong>as</strong>kunchakskaya". According to the Saratov section<br />

of speleology the cave h<strong>as</strong> the extent of 1480,0m, the<br />

maximal depth is about 32,0m, its volume is about<br />

9400,0m3. It is situated on the northwest co<strong>as</strong>t of<br />

B<strong>as</strong>kunchack in top reaches of the superficial drain<br />

Pezcernaja.<br />

Cave "B<strong>as</strong>kunchakskaja" h<strong>as</strong> some inputs and<br />

concerns to the type of horizontal through (through<br />

p<strong>as</strong>sage) caves; it h<strong>as</strong> been known <strong>for</strong> more than<br />

hundred years. It is actively visited nowadays.<br />

Golovachev I.V. describes three tens caves in<br />

gypsums with the extent of more than 10,0km., but only<br />

7 of these caves are examined and there are published<br />

data about them.<br />

The accumulative plain adjoins to the lake<br />

B<strong>as</strong>kunchack. According the geomorphological<br />

expressiveness it is subdivided into two subtypes:<br />

gently-wavy which is deposited on the hypsometric<br />

level 0 - minus 10m and flat located on absolute marks<br />

from minus 10m up to minus 21,2m (isohypse, outlining<br />

the lake).<br />

The flat sinuosity of the plain of higher hypsometric<br />

level is caused by non-uni<strong>for</strong>m accumulation of<br />

deposits, drifted from peneplains and the differentiated<br />

display of hydrochloric tectogenesis.<br />

From the surface the plain is combined by early<br />

Khvalynian adjournments which are blocked from<br />

above by dealluvial ones, with the impurity of chippings,<br />

brought from the mountain and adjoining to peneplains.<br />

The flat plain is a part of the lake bottom and is<br />

combined from a surface by oozy deposits of a lake<br />

origin with the impurity of small salt crystals.<br />

The width of accumulative plain varies from 3km in the<br />

settlement Nizchny B<strong>as</strong>kunchack is up to 0,5km in the<br />

southwest part. The relief is complicated with hollows of<br />

a drain which through peneplains cross the<br />

accumulative plain.<br />

Lake B<strong>as</strong>kunchack is a unique <strong>for</strong>m of a relief - mould,<br />

filled with halogen type of deposits. Prior to the<br />

beginning of industrial development of salt the whole<br />

12<br />

surface of lake represented a dense salt layer.<br />

Geophysical investigation h<strong>as</strong> shown that salt is<br />

deposited up to the depth of 600m, but deep from the<br />

surface it alternates with sand, clay. In the plan the<br />

lake h<strong>as</strong> the wrong <strong>for</strong>m with the general orientation<br />

in a northwest direction. The extent of the lake on the<br />

big axis is 18 km, the general area is 106 км2. The<br />

significant part of the lake area (60 %) <strong>as</strong> a result of<br />

salt extraction is occupied by broken zones. These<br />

zones represent sections from which salt is taken up<br />

to the depth of 8m. Broken zones are filled with brine<br />

with a mineralization of 300 g/l. Natural process of<br />

salt accumulation is broken.


C. ARGUMENTS FOR NOMINATING THE TERRITORY AS A EUROPEAN GEOPARK<br />

C.1. COMPREHENSIVE ANALYSIS OF THE TERRITORY'S<br />

POTENTIAL FOR THE DEVELOPMENT OF GEOTOURISM<br />

Due to the considerable presence of sites with<br />

geological, naturalistic and archaeological interest, the<br />

Bogdinsko-B<strong>as</strong>kunchaksky reserve h<strong>as</strong> notable<br />

potential <strong>for</strong> the development of Geotourism. The<br />

onservation and evaluation of the lithological and<br />

morphological characteristics takes on an important<br />

scientific value.<br />

These elements condition the geological evolution of<br />

the area. The area is well known in the tourist market<br />

because of the tourist resort Salty lake B<strong>as</strong>kunchak and<br />

not le<strong>as</strong>t the majestic mountain Bolhoe Bogdo.<br />

Optimum to use possibilities <strong>for</strong> tourism, the reserve cooperates<br />

with the scientific organisations which develop<br />

techniques <strong>for</strong> improvement of tourist activity. As <strong>for</strong><br />

attraction of different tourist groups the reserve will<br />

organise a museum of natural history which exposition<br />

will be very interesting to visitors of reserve and will<br />

interest people of visitors <strong>for</strong> survey of sights.<br />

For financing of individual programs on protection of<br />

surrounding wildlife and geological objects the reserve<br />

co-operates with the various international organisations<br />

which are engaged in nature protection, such <strong>as</strong> WWF<br />

(the world fund of the wild nature).<br />

C.2. OVERVIEW OF THE EXISTING GEOINSTITUTION AND<br />

GEO-ACTIVITIES IN THE REGION OF THE GEOPARK<br />

The Bogdinsko-B<strong>as</strong>kunchaksky reserve throughout<br />

many years actively co-operates with the leading<br />

scientific organisations. These organisations carry out<br />

thematic scientific researches of geology, ecology of<br />

flora and reserve fauna. These researches are spent<br />

more than 10 years.<br />

Such scientific organisations co-operate with reserve<br />

<strong>as</strong>: the Astrakhan state university (research of flora,<br />

karstic caves), the Astrakhan state technical university<br />

(geological researches), the Russian university of<br />

friendship of the people (fauna research).<br />

Regularly carry out researches employees of zoological<br />

institute of the Russian Academy of Sciences and<br />

biological institute of the Russian Academy of<br />

Sciences.<br />

The researches in the field of tourist activity in geopark<br />

territory are spent by Institute of ecology of the Volga<br />

pool of the Russian Academy of Sciences.<br />

The scientific organisations publish works which<br />

expand an outlook of scientific and practical knowledge<br />

of flora, to fauna and geopark geology.<br />

C.3. POLICIES FOR THE PROTECTION, ENHANCEMENT<br />

AND ECONOMIC DEVELOPMENT OF THE GEOLOGICAL<br />

HERITAGE PRESENT IN THE TERRITORY.<br />

The reserve establishment h<strong>as</strong> carried out numerous<br />

scientific researches rather.<br />

13<br />

The geological heritage of area also co-operated with<br />

the scientific organisations to make this heritage<br />

popular.<br />

To advance development Geotourism, Park in<br />

cooperation with municipalities and with the Agencies<br />

responsible <strong>for</strong> development of tourism, intends to<br />

involve tourist operators in initiatives which are<br />

promoting of geological and geomorphological<br />

extreme итуаций.<br />

The Park establishment develops long-term plans<br />

aimed at protection экосистемы reserve and its<br />

development. In con<strong>for</strong>mity with principles of a<br />

sustainable development the establishment spends<br />

scientifically-practical conferences to which agenda<br />

questions of preservation of the environment and<br />

development of tourist and recreational activity enter.<br />

Also the reserve with its unique natural and<br />

geological complexes lets out a lot of printing and<br />

souvenir production with the logos and symbolics.<br />

C.4. THE TERRITORY'S INTEREST IN JOINING THE<br />

EUROPEAN GEOPARK NETWORK<br />

The Bogdinsko-B<strong>as</strong>kunchaksky reserve <strong>as</strong>pires to<br />

become a <strong>European</strong> <strong>Geopark</strong> because, besides<br />

having a unique geological heritage, h<strong>as</strong> <strong>for</strong> years<br />

carried out a policy of sustainable development. It<br />

includes a number of geological sites of particular<br />

importance in terms of scientific quality, rarity,<br />

aestheticism and of educational value. The territory is<br />

not only important <strong>for</strong> its geology, it possesses an<br />

enormous rchaeological, ecological, historical and<br />

cultural heritage. The Park Institution intends to make<br />

use of the management results developed by the<br />

<strong>European</strong> Network of <strong>Geopark</strong>s, utilising the label<br />

and a common image of quality that emph<strong>as</strong>izes the<br />

valorisation of the geological heritage and the<br />

sustainable development. The Bogdinsko-<br />

B<strong>as</strong>kunchaksky reserve intends to collaborate with<br />

the <strong>European</strong> Network of <strong>Geopark</strong>s and with the local<br />

entrepreneurs to promote and support the creation<br />

and commercialization of new products connected<br />

with the geological heritage.<br />

The sites of the Bogdinsko-B<strong>as</strong>kunchaksky reserve<br />

will have their own website and will be safeguarded.<br />

The Institution of the Bogdinsko-B<strong>as</strong>kunchaksky<br />

reserve h<strong>as</strong> an active role <strong>for</strong> the economic<br />

development and the valorisation of the territory and<br />

its heritage and is working <strong>for</strong> the development <strong>for</strong><br />

geotourism. It h<strong>as</strong> a positive influence on the quality<br />

of life of its inhabitants. This means that the residents<br />

are actively involved with the cultural<br />

revival of the territory. The Institution also promotes<br />

education on the environment, the <strong>for</strong>mation and the<br />

development of Scientific Research in its various<br />

disciplines in the Science of the Earth, improving<br />

natural environment and encouraging Sustainable<br />

Development Policies.
