title: RHYTHMICITY OF LATE CRETACEOUS CARBONATE SEDIMENTATION IN THE BLACK SEA NORTHWESTERN SHELF
abstract: Integrated detail study we conducted for the Upper Cretaceous section of the deep wells drilled within the northwestern shelf of the Black Sea gave us a possibility to recognize a distinct and well traceable rhythmicity of sedimentation in the Late Cretaceous sequence deposited there. In the case of continuous rhythm the section demonstrate full paragenetic set of sequentially changed rocks: biogenicdetrital limestone (biogenic marl) – micritic limestone – chalk – micritic limestone – biogenic-d
