Definition

Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

Formation

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

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.
