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.

Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

All about Lherzolite and Siltstone Properties

Know all about Lherzolite and Siltstone properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Siltstone belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Siltstone is Clastic. Lherzolite appears Glassy, Vesicular and Foilated and Siltstone appears Rough. The luster of Lherzolite is subvitreous to dull while that of Siltstone is dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Siltstone is available in brown, red, reddish brown colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Siltstone are raw material for the manufacture of mortar, soil conditioner.
