State Geological Map at Scale 1

ORGANIZATION UNIT OF THE VICE-DIRECTOR FOR GEOLOGY * GEOLOGICAL DIVISIONGEOLOGICAL RESEARCH AND MAPPINGThe research of geological setting and geological evolutionof the Earth’s Crust linked with geological mappingcreates the basis of geology. The knowledge acquired bybasic geology creates groundwork for applied geologicaldisciplines. Naturally, it cannot be buried in the unchangeddogmatic positions; the optimization process and enhancementof geological setting understanding is crucial for allthe activities concerning the Earth’s Crust. The absenceof actual geological information is frequently negativelyreflected in the sphere of economic activity and protectionof the Slovak environment. For instance, without basicgeological maps it is impossible to design large line structures,tunnels, water-work structures, repositories of radioactivewastes and further objects important from the pointof view of the state economy. The knowledge of geologicalsetting is a precondition for geothermal boreholes design,groundwater flow modeling, search for suitable sites for repositoriesof various kinds of waste etc.To be true, creation of geological maps is a never-endingstory. However, to date it is not so intensive as in previousyears. We must bear in mind, that this kind of activitycannot be fully abandoned. The continuity breach wouldbe manifested in various spheres, for instance in costs increasefor extensive investments units. The State GeologicalInstitute of D. Štúr as the only organization in Slovakiadisposing of high scientifi c potential compiles and issuesgeneral, basic and thematic geological maps at requiredscale.Fundamental geological mapsat scale at scale 1 : 25 000Fundamental geological maps constructed on topographicmap sheets at scale 1 : 25 000 represent a primarygroundwork for compilation of geological maps of smallerscales (1 : 50 000, 100 000, 200 000 and 500 000). For allthe Slovak regions, which are published at scale 1 : 50 000they have been compiled as inter-scale manuscript maps,which are archived and made available to all clients of theGeofond archive.Regional geologicalmaps at scale 1 : 50 000Geological maps of integral regions at scale1 : 50 000 are constructed based upon mapgroundwork of the fundamental scale 1 : 25 000.The maps of this scale are issued in print form withaccompanying text explanations.In the year 2007 there were accomplished theregions of the Považský Inovec Mts. and SE partof the Trenčianska kotlina Basin. New geologicalmap of the Spišsko-gemerské Rudohorie Mts,from the historical point the richest region in rawminerals, was submitted for printing.During the year 2007 there continued fi rst of allmapping and subsequent processing of petrographicand palaeontologic samples in the scope of the projectsGeological map of the Malé Karpaty Mts., Geologicalmap of the Záhorská nížina Lowland, Geological map ofthe Nízke Beskydy Mts. – western part and Geologicalmap of the Biele Karpaty Mts. – southern part and theMyjavská pahorkatina Upland.The objective of the above projects was to construct theupdated geological maps, which would fully meet criteria forgeological map of a state-of-art concept, which allows to incorporatethem into the digital geological map at scale 1 : 50 000.In the scope of the project Update of Geological SettingSR continued the works aiming on clarifying of geological settingof problematic territories and regions in which we are still lackingof the geological map at scale 1 : 50 000: Update of the Quaternaryof the SE Part of the East-Slovakian Lowland at the Contactregions with non-approved thematic geological groundworkregion covered by regional geological maps issued onor without geological maps (only with updated regions for the needs ofnon-deformed topographic groundwork (1992 – 2007)Digital Geological Map at scale 1 : 50 000),or with geological map at scale 1 : 25 000 solelyregion covered by regional geological maps issued onregion covered by regional geological maps completeddeformed topographic groundwork (1973 – 1992)by 2007Status of regional geological mapping at scale 1 : 50 000 in 2007.State Geological Institute of Dionýz Štúr Annual Report 2007 9
