Nummulitic facies of the Crimean-Caucasian Region

The nummulitic limestones of Crimea and the southwestern Caucasus, often interpreted as “nummulite banks”, formed carbonate platforms throughout most of the Ypresian–Lutetian. Such deposits were accumulated in shallow warm-water basins of Crimea and the Caucasus, which differed from each other by the structure of the basement and the hydrodynamic regime.
