Upper Quaternary evolution of the Mamaia Lake area (Romanian Black Sea shore)

Late Quaternary climate changes triggered the succession of several sedimentary environments, especially in the areas close to the current Romanian Black Sea shoreline. These have resulted in the succession of continental and marine lithofacies. The Mamaia karst depression consists of a sedimentary fill, which contains two marine transgression sequences (Surozhian and Holocene) divided by a sedimentary break, corresponding to the MIS 2 regression. The samples from two cores from the Mamaia barrier beach were analysed for lithology, texture, mineralogy, and fauna (molluscs, foraminifera, and ostracods).
