To the problem of origin volcanoplutonic processes

Abstract

In the article from the position on the Concept of the Dynamics of the Earth’s Crust Evolution (CDECE) the problems of the origin of volcanoplutonic processes and related endogenous ore formation are considered. It is established that geodynamic forces are created when the Earth rotates around its axis, all global geotectonic processes occur under the influence of these forces. These forces in the face of the Earth spread with certain regularities. Movements of lithospheric masses on the surface of the upper mantle occurs under the influence of these forces. It is known that the geospheres of the Earth have different physical characteristics. Therefore, they react differently to the Earth’s rotation. For this reason, mass shifts occur between the differently characterized geospheres. Because of these displacements between geospheres physical-chemical phase transformations form, where decomposition of mantle matter occurs, which is associated with the increase in the volume of mantle matter, that further, is associated with the formation of primary magma, which is associated with the manifestations of volcanoplutonic processes and earthquakes. These physical and chemical phase transformations theoretically occur in all zones between different geospheres of the Earth. However, the most intensive manifestation of them occurs between the Earth’s crust and upper mantle, associated with the increase in the radius of rotation of the Earth. The speed of movement of lithospheric masses is connected with the regularities of distribution of geodynamic forces, which have differential character of development this is connected with geometrical parameters of the Earth where the directions of movement of lithospheric masses, occur from west to east. In these conditions, the rate of movement in near equatorial zones have a maximum value, and in the direction of the poles reduce to zero. This is due to the fact that the Earth’s radius is located perpendicular to its axis of rotation. Therefore, the velocity of lithospheric masses movement in its equator have maximum values, which in the poles decrease to zero.
