The paper describes the petrographic composition of moraine materials, indicating their Uralian origin.
The paper describes petrographic composition of the rocks from a new collection of fragmentary material from a known outcrop of glacial deposits on the righthand bank of the Bolshoi Yugan river upstream from Izby Eutskie. A set of petrographic varieties and the fossil composition in sedimentary rocks unambiguously indicate the Uralian origin of the moraine. The band where the Uralian and Siberian glaciers join in the epoch of Samarian glaciation is supposed to be east of the B. Yugan valley.
