Title: PETROTYPES OF SANDSTONES OF THE SHESHMINSKY HORIZON IN THE SOUTHWESTERN PART OF THE SOLIKAMSK DEPRESSION
Abstract: The results of petrographic studies of sandstones of the Sheshminsky horizon are presented. The main components of the clastic phase have been determined. The studied section contains only lithite arenites, among which five petrographic varieties have been identified. The source of clastic material was probably five different complexes: volcanic and plutonic rocks of intermediate and basic composition, sedimentary, metamorphic and quartzite sequences
