Cretaceous transgressions and regressions on the Russian Platform, in Crimea and Central Asia

Abstract

This paper is a brief explanation of the diagrams of the Cretaceous transgressions and regressions on the Russian Platform, in the Crimea (Figures 1–3) and some regions of central Asia—the western flanks of the Tien Shan mountains, the Fergana basin, the Zeravshan-Gissar and Alaj mountains, and the Northern Pamirs (Figures 5–7). Internationally recognized stages are employed. They are interpreted by Sasonova (1967) for the Lower Cretaceous (K 1) of the Russian Platform, by Naidin (1977) for the Upper Cretaceous (K 2) of the Platform and the Crimea, by Djalilov (1971) and Pojarkova (1976) for the Upper Cretaceous of central Asia. General data on the stratigraphy of the Cretaceous of central Asia may be found in Anon 1977.
