Geologicheskii Vestnik

The article presents the results of mineralogical studies of the Vendian Staropetrovsk Formation in the section of the new well 40 Krasnousolsk, which are used to resolve the issues of subdivision and correlation of the well section with similar formations of the key sections of the Shkapovo-Shikhan depression (along the profi le of wells 20007 Sulinsk – 4 Aslykul – 6 Akhmerovo) and of the Southern Urals, determination of provenance areas of clastic material and the features of the development of the sedimentary basin in the Staropetrovsk time of the Vendian. Based on the example of deposits of the Staropetrovsk Formation, which is an age analogue of the Basu Formation of the Southern Urals, it was established that the Uralian and Volga-Uralian basins had a common development in the Vendian time.
