The Basic Geological Map (BGM - SFRY, 1:100 000)

The Basic Geological Maps of the SFRY depict the geological setting and the evolutionary history of the terrain from the Paleozoic to the Quaternary, spanning a time interval of over 600 million years. These maps also delineate the key tectonic structures that influenced the regional geological evolution. Furthermore, the maps comprise data on mineral resource occurrences, fossil localities, and other significant geological phenomena. Through these systematic investigations, a vast amount of factographic data was compiled, enabling the study of the structural framework of the primary geotectonic units, as well as a significant refinement of the vertical boundaries within the chronostratigraphic column. The discovery of formations originating from the earliest stages of the Earth's crust evolution, combined with new data on the detailed subdivision of Mesozoic, Tertiary, and Quaternary sediments, has provided the basis for addressing numerous practical challenges within the territory of Republika Srpska. Today, these maps represent a fundamental source of information for geological exploration, spatial planning, and natural resource exploitation. The territory of Republika Srpska is covered by 43 sheets of the SFRY Basic Geological Map at a scale of 1:100,000.
