Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Granophyre 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.
