Definition

Mangerite is a plutonic intrusive igneous rock, which is essentially a hypersthene-bearing monzonite

Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

Formation

Mangerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
