Includes fossils?Y
Lithology description: "The sequence of calcareous shales, commonly with tuffaceous intercalations, occupying the lowermost part of the Kopanina Formation, is overlain by bioclastic limestones of the E. beaumonti Horizon of the lower Kopanina Formation..." "...biosparitic limestone and laminated, argillaceous limestones..."
Environment:marine indet.
Geology comments: "Decrease in volcanic activity...provided favorable conditions for carbonate sedimentation and the development of fauna on the NW flank of the 'syncline' whereas calc. shale sed. dominated by graptolites continued along the SE limb...The high dominance, low diversity atrypid and athyrid lenses may represent BA 2, quiet water, restrictive conditions...[various aspects of shell preservation discussed, as well as shell accumulation indicating rough water in places...] Prevalence of small, smooth brachiopods and numerous trilobites is consistent with BA 3-4 position that graded laterally in calc. shales dom. by graptolites..."
