1 Definition
1.1 Definition
Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
1.2 History
1.2.1 Origin
1.2.2 Discoverer
1.3 Etymology
From the chemical and mineralogical composition of the upper mantle of the Earth
From 17th century, because of its greasy feel and use like a soap

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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.
