Stratigraphy
Stratigraphy comments: Isakovtsy "subsuite" of Malinovtsy "series" and Varnitsa "suite" of the Ruksing "series" (Skalian "superhorizon"). See fig. 38.1 for correlation chart.
Lithology and environment
Primary lithology:dolomitic "limestone"
Secondary lithology:shelly/skeletal argillaceous "limestone"
Includes fossils?Y
Includes fossils?Y
Lithology description: "Occurs in massive, fine-grained Lst (commonly dolomitized in the Isakovtsy subsuite) and in platy, argillaceous, organodetrital limestone."
Environment:marine indet.
Geology comments: "...argillaceous Lst [interpreted as ] deposited on a closed shelf. Trilobites suggest a reasonable level of turbulence. Fossils are rare. Brachiopods disarticulated. The rocks are detrital clastics. This is a BA 2 community, i.e. shallow water."
