The middle carboniferous of Russia - 433-441p.
Extract
The present paper summarizes some of the recent work on the stratigraphy of the Middle Carboniferous in the south-eastern and eastern parts of European USSR., work which throws new light on the position of the Moscovian stage in the Carboniferous succession. The Moscovian stage is at the present generally accepted as corresponding to the whole of the Middle Carboniferous (Danshin, Schwetzow, Khimenkow, and others), but the evidence of a break at the base of the Moscovian beds near Moscow justifies us in putting the question—is the Moscovian stage to be regarded as corresponding to the whole series of Middle Carboniferous deposits or was the deposition of the Moscovian series of beds preceded by erosion not only of part of the Lower Carboniferous, but also of part of the Middle Carboniferous? At the same time the new data concerning the character of the boundary of the Moscovian with the Upper Carboniferous tends to prove that at this boundary also there are signs of a hiatus.
