Magma solidification processes.
From slowly cooling magma in the upper parts of the earth's crust, but at some distance from the surface, at a temperature of about 110CTC, individual minerals begin to crystallize. Magma consists of components with different freezing points …
MAGMA ROCKS
The first material in the earth's crust are crystalline rock masses, mainly composed of silicates. They were formed by solidifying a hot silicate alloy, from deeper parts of the earth's crust. This silicate alloy is called magma, and the products of its solidification with igneous rocks …
