Stratigraphy
Formation:Tsninskaya
Local section:Izvarino Local bed:L 4/1
Stratigraphy comments: as with most Pennsylvanian sections in the Donets Basin, fine-grained sandstones, siltstones, shales, coal seams, and limestones alternate cyclically

a useful nomenclatural scheme specific to the Donets Basin was developed by Ukrainian geologists at the end of the nineteenth century. The Carboniferous sequence is divided into suites designated by letters. Capital letters refer to major marine limestones and numerals indicate stratigraphic order. Subordinate limestones with minor thickness overlying a major limestone are designated by a superscript numeral. Lower case letters indicate the coal seams of a suite, also with numbers for stratigraphic order.
The Moscovian Stage in the Donets Basin comprises the upper part of the K (C low2 upper5 ) suite, the L (C low2 upper6) suite, the M (C low2 upper7) suite, and the lower part of the N (C low3 upper1) suite.
The Izvarino section is continuosly exposed along the railway and ranges from limestone L (low4) to M (low1)
