Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Archaeological Significance
Formation
Wehrlite 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.

All about Wehrlite and Quartzite Properties
Know all about Wehrlite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Wehrlite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Wehrlite is Banded whereas that of Quartzite is Foliated, Granular. Wehrlite appears Rough and Banded and Quartzite appears Lustrous. The luster of Wehrlite is metallic while that of Quartzite is vitreous. Wehrlite is available in dark greenish - grey, green colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Wehrlite are cemetery markers, creating artwork, gemstone, jewelry and that of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
