Geologicheskii Vestnik

The “Toratau” Geopark, which is located on the territory of the Gafuri, Ishimbay and Sterlitamak regions of the Republic of Bashtortostan, is in its infancy. Most of the geopark area will be confi ned to the Fore-Ural foredeep and partially to the western slope of the Southern Urals. The Mesozoic is represented by small areas of marine deposits of the Upper Cretaceous; the outcrops of the continental Triassic are known north and south of the characterized territory. Cenozoic sediments are represented by rocks of the Paleogene, Neogene and Quaternary systems. Continental Upper Eocene sediments are attributed to the Paleogene; the Neogene is represented by continental Miocene and Pliocene deposits, and the Qauternary is represented more widely by marine Palaeopleistocene, continental Eopleistocene, Neopleistocene, and also Holocene formations, forming palaeohydrographic valleys of Belaya river and its tributaries. An analysis of the state of study of the Mesozoic and Cenozoic deposits of the territory shows their weak characterization at the modern level and emphasizes the need for their further study as а part of the state geological survey of sheet N-40-XXI at a scale of 1:200000, currently carried out, and the emerging “Toratau” Geopark. Such work is necessary to understand the development of the territory both in the past and in the near future, to prevent a development of dangerous exogenous geological processes, as well as to preserve the geological heritage, which is the main task of geoparks.
