A sedimentation model of the maikop deposits of the Tuapse Basin in the Black Sea according to the results of 2-D and 3-D seismic surveys and field works in the Western Caucasus and Crimea

This work is based on the results of 2-D and 3-D surveys in the Tuapse Basin and field works in the Crimea-Caucasus region. Seven zones were outlined in the model of sedimentation starting from the eroded mountain structure of the Greater Caucasus down to deep water sediments of the Tuapse Basin. The slope and deep-water sediments of channels and fan complexes are characterized. Volume models of the sedimentation system in the Black Sea are shown for the first time.     

Modern erosion and sedimentation processes in the deep-water part of the Tuapse Trough based on the data of 3D seismic survey

On the basis of new 2D/3D seismic data, the modern tectonic, erosion, and sedimentation processes have been studied in detail in the Tuapse Trough of the Black Sea. The principal processes identified are growth of anticline folds, erosion of submarine ridges, and formation of submarine channels and modern small basins. It has been shown that erosion of submarine ridges took place throughout the entire evolution of their growth.     

The sedimentation model of the Tuapse Trough (Black Sea)

Based on the new 2D and 3D seismic data from the Tuapse Trough (Black Sea), the principle peculiarities of sedimentation have been studied in detail. A sedimentation model of the focused Maikop and Karagan-Chokrak intervals of the geological section has been suggested. A system of fan complexes referred to Maikop age has been found.
