5 Formation

5.1 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.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
