Morphostructures and the sedimentary cover structure of the Western Crimea inner shelf

Abstract

The results of geophysical and geomorphological works on the Western shelf of the Crimea peninsula (Evpatoria-Balaklava) are presented. The structure of the sedimentary sequence, the bottom topography and paleogeographic reconstructions of the conditions of the western shelf formation in the Late PleistoceneHolocene are considered. Based on the analysis of geoacoustic profiles, the main morphostructures of the shelf are identified and their brief characteristic is given. An abrasion-accumulative complex consisting of an abrasion platform and an associated accumulative clinoform, the formation of which is associated with the coastal line of the Late Pleistocene Black Sea regression to depths of about -90 m, traced from Yevpatoria to Yalta, was selected. On the shelf of the Kalamitsky Bay, fragments of the flooded river network and coastal accumulative forms such as bars were investigated.
