title: Late Cenomanian Paleoecological Event OAE 2 in the Sections of the Northern Peri-Tethys (Crimea, Eastern Caucasus): Sediment Structure and Dynamics of their Accumulation
abstract: The comparative characteristics of sedimentary successions corresponding to the paleoecological event OAE 2, which are spaced over 1000 km apart within the Crimean–Caucasian region, are present. It is shown that the sediments accumulated during this time span under different sedimentary conditions are featured by the similar structures. The sedimentological, geochemical, and paleoecological analyses, indicate that (1) stable oxygen deficient conditions were not spread in the water column of the
