Аннотация:The determination of the Oldeuxinian and Uzunlarian sediments on the Bulgarian Black Sea coastal zone for the first time is a quality of this paper. A detailed lithological and biostratigraphical research on molluscan fauna and an analysis of the terrace complex are made. The discussed core in Kamchia river mouth recovers a Quaternary section with a remarkable stratigraphical range.The established marine phases of sedimentation mark transgressive stages of the palaeogeographical development of the Black Sea basin during the Middle Pleistocene.
The climatic changes and palaeogeographical conditions of the Oldeuxinian and Uzunlarian basin are reconstructed and discussed.
