Abstract
The paper examines a possible relationship of the occurrence of catastrophic situations (earthquakes, rock bursts, etc.) in unordinary conditions and manifestations of tectonic processes in the bowels of the Earth at the “lower crust-upper mantle” level. It is shown that such tectonics is observed in basite-ultrabasite xenoliths bearing clear features of deep-seated deformation (olivine twinning, curved crystals, drag grains of spinel, preferred orientation of optical indicatrices of minerals, etc.). The mentioned relationship is studied from the viewpoint of relaxation reaction of rock masses, rocks and their element components on mass displacements in the Earth’s depths.
