MORPHOGENETIC CLASSIFICATION OF MUD VOLCANOES IN THE CASPIAN SEA AZERBAIJAN AQUATORIUM

(Hadjiyev A.N., Bagirova U.A.)



Summary


Mud volcanoes are concentrated mainly in sedimentary basins, dominated by fusing subsidence and the dynamics of the current fluid flow. They are a source of information on paleogeographic conditions. In the area of the Azerbaijani sector of the Caspian Sea is observed about 200 mud volcanic structures. Mostly they stretch up to several kilometers across and several hundred meters in height. Most of the mud volcanoes in our study area is located over anticlinal complicated faults. In southern waters of the South Caspian basin are not subjected to erosion young volcanoes taller than 250 m. The roots of most volcanoes are related to Cretaceous and Paleogene-Miocene sediments. The analysis of seismic data for the first time to identify 12 of morphogenetic types of volcanoes. Cycles of activity of mud volcanoes in the South Caspian megadepression associated with time of intense sedimentation, periodic regional compression and main stage of hydrocarbon formation.
