High frequency sea level fluctuations recorded in the Black Sea since the LGM ArchiMer
Lericolais, Gilles; Bulois, C.; Gillet, Herve; Guichard, F..
This paper presents a 3D geometric interpretation of very high resolution seismic Chirp profiles acquired on the Romanian shelf during ASSEMBLAGE European Project. The results provide a solid record of the Black Sea Last Glacial Maximum (LGM) water level fluctuations. This pseudo-3D seismic interpretation shows that the Black Sea lacustrine shelf deposits form a significant basinward-prograding wedge system. on top of these prograding sequences is a set of sand dunes that delineates a wave cut-terrace like feature around the isobath -100 m. Landward of this dune field are small depressions containing barkhan-like bodies. The upper part of the last prograding sequence is incised by anastomosed channels which end in the Danube (Viteaz) canyon which are also...
