Pyrolite and Novaculite

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

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.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.
