【 摘 要 】

The article delivers a comparative analysis of the diapir structures of the Tersko-Sunzhenskaya oil-and-gas region of the Eastern Ciscaucasia, which are represented in the form of quasi-muddy, young (not yet ripe) volcanoes, and mud volcano structures on the territory of the southeastern end of the Caucasian ridge (Apsheron peninsula and other territories of Azerbaijan) and the northwestern end of the Caucasian ridge (Kerch and Taman peninsulas). It is shown that the formation of the diapir structure is not a sufficient condition for its degeneration into a mud volcano even when there is a high thickness of clayey strata in the section. The paramount significance in such geological conditions is determined not only by the thickness of the clay stratum, but also by the degree of its water-saturated porosity, which forms viscous-plastic and fluid properties that facilitate the transition of the rock to the phase of active flow and outflow onto the surface.
