Geologicheskii Vestnik

The features of the structure and composition of the Upper Riphean Katav Formation in the northern part of the Inzer synclinorium in the sections along the Bolshoi and Malyi Kazamash rivers are considered in the area of Splavnoy village (Southern Urals). Sections of the Katav Formation of the northern (along the Bolshoi and Maly Kazamash rivers) and central (near the village of Inzer) parts of the Inzer synclinorium have similar structural features. In the outcrop along the river. Bol. Kazamash in a continuous sequence, the character of the transition of the Katav striated limestones with the overlying Podinzersky limestones of the Inzer Formation is observed. The deposits of the Katav Formation in the above sections, which have layers undisturbed by tectonic processes, gently dipping into a monocline, are a good object for lithostratigraphic and paleomagnetic studies. Further detailed studies of the deposits of the Katavskaya and other formations of the Upper Riphean within the Bashkirian meganticlinorium in the Southern Urals will make it possible to clarify the features of the formation of a large Upper Riphean sedimentary basin in the Southern Urals.
