摘要: The ages of volcanic activity in the Crimea and North Caucasus are reported this paper. age estimation described ranges is based on results micropaleontological analysis (planktonic Foraminifera) with account for data other groups, mostly Ammonites Inoceramids. Volcanic rocks related to Upper Albian (Thalmanninella appenninica Zone), Lower Cenomanian globotruncanoides Zone) deposits, boundary deposits Middle deeckey Middle-Upper (Rotalipora cushmani Zone). was found Campanian Stage (Globotruncanita elevate Globotruncana ventricosa) as well.
