1 Definition
1.1 Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

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.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Lherzolite and Schist Properties

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