- Аннотация: A combined statistical analysis is made of the strikes of the movement planes at the foci of weak earthquakes with M = 1 -4 ("Seismic jointing") and the lineaments of the erosion patterms of the Garm region. In the corresponding azimuth distributions two systems of conjugate, mutually orthogonal directions are distinguished: 0° and 90°, ~40° and -140°. A study is made of the dependence of the shape of the distributions being compared on the type of stress - strain state for various blocks of the earth's crust. It is concluded that there exist in the crust of the investigated region two systems of conjugate, mutually orthogonal cleavages.
