STRUCTURAL POSITION AND THE PROBLEMS OF MUD VOLCANISM CENTERS APPEARANCE IN THE POST ALPINE PLICATED CONSTRUCTION OF THE NORTH-WESTERN CAUCASUS (BASED ON THE EXAMPLE OF THE STUDY OF THE DEEP STRUCTURE OF THE MUD VOLCANO SHUGO)

Abstract

The majority of mud volcanoes is located along the large tectonic zones of Mediterranean and Pacific Ocean mobile belts. The important condition for mud volcanoes processes are plicated deformations and disjunctive dislocation of sedimentary formations. Volcano Shugo - one of the most known active mud volcanoes of Taman mud volcanoes province in the North-Western periclinal part of the Alpine plicated construction of the Great Caucasus. The volcano has relatively calm «nature», but in 1903, 1908 and 2006 yr. short-term stormy eruptions were observed.The new geophysical data about the deep structure of the Shugo volcano enlarge our ideas about the mechanisms of this geological object activity taking into account available material about its structural- geological position. Duringthe field works we have refined its deep structure and acquired data about the interstitial- explosive structures of the volcanic building, which make it possible to pass to the examination of the tekto-dynamical conditions for the formation of the Shugo volcano.
