Pyrolite and Pseudotachylite

1 Definition
1.1 Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.

1.3 Etymology
From the chemical and mineralogical composition of the upper mantle of the Earth
From pseudo- +‎ tachylite, a glassy rock generated by frictional heat within faults.

5 Formation
5.1 Formation
Pyrolite 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.
