Sequence-stratigraphy of Neogene-Quaternary section in north-western aquatorium of the Black Sea
In present article Neogene-Quaternary section of north-western part of the Black Sea is analysed from the standpoint of sequence-stratigraphy. Data interpretation was carried out using materials of regional 2D-seismic profile series. Peculiarities, determined in the shelfy part, are: 1 - significant erosional unconformity with relief up to 500 m, probably formed as the result of the Messinian Event; 2 - incised valley, up to 400 m deep, which is, apparently, the submarine extension of Paleodnepr. Complex of large abyssal detrital cones, filling in sequence sedimentation volume with considerable sea-level variations, was identified in abyssal zone of the Western Black Sea depression. The detailed analysis of genetic relationship between these elements of section allowed to form a notion of spatial distribution of depositional environment and geologic factors, affecting their development. These results made it possible to predict promising objects during exploration, which was the main target of this research.
