Geodynamics and the Relationship of Uranium Metallogeny in Mongolia
摘要
Geodynamics is a science which studies all the deep-seated processes of the earth including ravel of material and involved forces, as well as a reflection on the lithospheric plates and earth’s crust. As a result of these forces, the deep materials in the earth shift, both horizontally and vertically. The morphological processes differ and can be effusive and intrusive, as well as forming sedimentary rocks during different geodynamical conditions. Origin of these geodynamic environments formed one after another successively replacing each other. For example, first formed was a spreading situation in a destructive tension oceanic crust and an oceanic plate was created. Then that plate plunged into azone of a deep-water trench and created a subduction environment and here a convergent process began Then, weak subductants, in this lithospheric plate in the zone of Bienof, partially melts into andesite magma, part of which rises to the surface of the Earth and forms an island arc in the boundaries of the ocean (transitional crust) of marginal-continental arcs in limits of the continent. It creates an accretionary environment. As a result, crust grows both vertically and horizontally. After the accretion process, felsic and acidic-alkaline products of a collision situation are generated. Thus, within the limits of this transitional crust, a continental crust forms on the edge of the ocean. Genetically, related geodynamic environment replacements are based on the theory of tectonics lithospheric plates.
