Formation

Trachyandesite 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.

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