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