Definition

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

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

Etymology

From quartz + -ite

From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

Formation

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

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.

All about Quartzite and Lherzolite Properties

Know all about Quartzite and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Lherzolite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Lherzolite is Grenue. Quartzite appears Lustrous and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Quartzite is vitreous while that of Lherzolite is subvitreous to dull.
