摘要

In the current article, we examine the tectonophysical parameters of Mt. Beshtau. A number of facts indicate that the Mt. Beshtau is developing according to the protrusive uplift type, as is the Khibiny Massif. Concentric fracturing was recorded along the periphery of the massif, which emphasizes the newest stage of development of the massif. The overwhelming number of determinations of slickensides indicate a normal-fault kinematics. Calculation of geological stress indicators allows us to suggest an extensional regime. These data lead to the conclusion that during the neotectonic stage, Mt. Beshtau is undergoing an annular subsidence with he general uplift of the massif. In the southwestern part of the faults, confined to the Skala vein system, strong seasonal radon emanation anomaly has been revealed, which is probable evidence of high-permeable rock of the massif. The results from studying this territory by different tectonophysical methods indicate the high reliability of the conclusions.
