On the biostratigraphy and cyclostratigraphy of the Moscovian Stage in the type area

Moscovian Stage deposits are widespread in Russia. The stage was established in 1890 by Nikitin. It is subdivised in four horizons: Vereya, Kashira, Podolsk and Myachkovo. The subdivisions of the stage are based on studies of brachipods, foraminifera, conodonts, ammonites, bivalves, rugosans and plants. In this paper, new data are due to the correction of the standard section of the Moscovian Stage and its new interpretation. Cyclostratigraphy analysis based on the geological history of the region and its eustatics is a new aspect of the research presented in this paper.
