“…It belongs to the group of passive seis mic methods and can be applied for solving geologi cal geophysical and structural tasks for different classes of geological objects in various geographic and climate conditions (Gorbatikov et al, 2008;Gorba tikov and Tsukanov, 2011). To date, significant experi ence has been gained in applying the MS method in the research and industrial projects in the territory of Russia, CIS, and abroad (Gorbatikov et al, 2008;2015;Rogozhin et al, 2009;Kugaenko et al, 2013).…”

The model of the magmatic system beneath the Uzon-Geizernaya volcano tectonic depression and adjacent Kikhpinych volcano in Kamchatka is constructed to a depth of 30 km based on the microseismic sounding data. For doing this, measurements of the natural microseismic field by the Guralp CMG 6TD portable broadband seismometer were carried out at 60 points along three profiles with a total length of about 28 km. The revealed structural heterogeneities were interpreted in the common context with the previous geological, geological morphological, and petrological results. The area of a shallow crystallized magmatic reservoir is identified and spatially localized below the depression. The zones of the presumed concentration of the basaltic melts probably responsible for the local geodynamic activation of the region during the past 15 years are revealed as the peripheral magmatic chamber of the Kikhpinych volcano at a depth of 5-12 km and a deeper (15-20 km) magma storage. The geometry of the identified deep structures is consistent with the local microseismicity and the model of the contemporary magmatic intrusion into the upper crustal layers, which is based on the data of satellite interferometry.

The article highlights the results of the first GPS measurements carried out along a geodetic profile that intersects all major geological structures in the Ossetian region of the Greater Caucasus. The interpretation of the measurement results was made in comparison with the results of neotectonic studies and data on the deep structure. The maximum decrease in the current transverse compression velocities was recorded in the region of the highest rise above the Earth's surface of a low-Q volume of the Earth's crust, which has a widening effect on the entire mountain structure. The presence of significant transverse displacements of the surface reflects the shear component along the largest faults of the Caucasian strike. The previously prognosticated significant decrease in the velocity of horizontal movements at the end of the aftershock process of the catastrophic Racha earthquake of 1991 on the southern slope of the Greater Caucasus was fully confirmed.

The article considers the complex analysis of geological data on the basis of the use of the high-velocity model of the microseismic sounding method (MMS) on the sections of the Central Caucasus. At the same time, based on the analysis of the results obtained, the high potential possibilities of the MMS method are shown in conditions of deep development of tectonic processes. Geological and geophysical data confirming the correspondence of anomalous objects to the velocity model of MMS with known structures and tectonic dislocations located at considerable depths are given. It is concluded that the use of MMS has a good prospect. It can become a direction of innovative development not only in the study of deep and oil-andgas bearing structures, but also in the search for ore deposits through the solution of structural-tectonic, lithologic and morphological signs of ore occurrence control and a systematic understanding of the factors responsible for the formation of metallogenic specialization, geophysical fields and the geological structure of metallogenic zones, ore fields and deposits.
