Magmatic Rock

Magmatic rock, also known as igneous rock, is formed by condensation of magma and is the final product of magmatic activity. It is the main body of three major types of rocks, accounting for 64.7% of the volume of crustal rocks. Magmatism refers to the development, movement, condensation, and consolidation of magma into igneous rock.

According to the occurrence of magmatic rocks, rocks formed by magma eruption and condensation consolidation are extrusive rocks; Deep magma migrates upward and invades surrounding rocks. The rocks formed by condensation, crystallization, and consolidation underground are intrusive rocks.
