Websterite vs Quartzite


Definition

Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone  
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.

Formation

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.   
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.
