Abstract
The Sorokin Trough (Black Sea) is characterized by diapiric structures formed in a compressional tectonic regime that facilitate fluid migration to the seafloor.
We present acoustic data in order to image details of mud volcanoes associated with the diapirs.
Three types of mud volcanoes were distinguished: cone-shaped, flat-topped, and collapsed structures.
All mud volcanoes, except for the Kazakov mud volcano, are located above shallow mud diapirs and diapiric ridges.
Beyond the known near-surface occurrence of gas hydrates, bottom simulating reflectors are not seen on our seismic records, but pronounced lateral amplitude variations and bright spots may indicate the presence of gas hydrates and free gas.
