DYNAMICS and ACTIVE PROCESSES - International Lithosphere ...

In new geological map of Albania (in sc. 1: 200 000), the eastern contact of Ionian Zone
and the age of evaporate substratum there are presented by mistake. Melesini carbonate
massif east belongs to Ionian Zone (Misha V., 1975, Serjani A., 1984), and Permian age
of evaporate substratum is determined (Diamanti F., 2002).
In “Thrust Tectonics in Albania” Symposium, held in Tirana ( November, 1990),
Prrenjasi E. (1991) emphasized that limestones are covered under the lower flank of
structures, Tushaj D. et al. (1991) represented carbonate platform (Adria micro plate)
plunged deep to the east below Orogen up to the Vlora-Elbasani-Dibra transversal fault,
retrocharriages from west to the east were presented as well (Serjani A., 1991) .
Papazachos V. K. (2001) argued the distribution of earthquakes along with the contact of
Hellenic Trench with Eurasian Plate and further northwest along with the contact of
Apulian Plate (Adria micro plate) with Orogen (Eurasian Plate) as well.
K. A. Nikolaou (2001), determined as the most important factors of hydrocarbon
generation: the reversible and thrust faults and evaporates. V. Karakitsios, et al. (2001),
as main source of hydrocarbons determined amonitico rosso of Toarian, and a specific
horizon inside the evaporates. They suppose that “the potential traps are related to small
anticlines…” D. Mountrakis (2001) has put the idea that during the orogenic processes of
Alpine–Meogean, a migration towards the southwest direction of compression and
extension tectonic events caused the successive subduction towards the southwest.
The CORRELATION of the STRUCTURAL CHAINS
The authors argue that as all over Ionian Zone, in this area, structures were formed in
form of anticline and syncline chains, but later, tectonic events deformed their forms and
primary position. The main structural chains west of Fterra thrust there are as following
(Fig. 1, 2):
-Syncline chain: Fterra-Shen Vasil-Aliko-Livadhja-Shales-Sajadha Bay in Greece. Below
thrust plane to the east of this syncline chain must be buried the western flank of Fterra
anticline chain, jumping and splitting.
-Anticline chain: Qeparo-Kakome-Butrint-Çiflig-Pagane in Greece. Bogazi anticline and
Mile-Bufi structural nose are part of eastern flank of this anticline chain.
-Syncline chain: Kudhes-Butrinti Bay-Southeastern limit of Korphy Island.
-Anticline chain: Çika-Pilur-Korphy. On the surface it is outcropped only eastern flank,
placed directly on the thrust plane. Only in Llogara Pass thrust fault coincides with the
contact between African Plate (Adria micro plate) and Orogen. Below Çika thrust fault,
underneath the eastern flank, it is buried western flank of this anticline chain, and Dukati
syncline chain.
-Syncline chain: Dukat-Western Korphy, which is compressed and buried because of the
collision of Adria Platform with Orogen. We think that this chain it is wider and covered
in depth.
In above mentioned structural chains there are variation and inclinations of the crest lines
as result of orogenic polarity, and may be there are formed small structures and structural
noses, but all times belonging to the same structural chain.
