1.1 Definition

Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

5 Formation

5.1 Formation

Lherzolite 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 Lherzolite and Quartzite Properties

Know all about Lherzolite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Lherzolite is Grenue whereas that of Quartzite is Foliated, Granular. Lherzolite appears Glassy, Vesicular and Foilated and Quartzite appears Lustrous. The luster of Lherzolite is subvitreous to dull while that of Quartzite is vitreous. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums 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.
