Formation

Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.   
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 Peridotite and Siltstone Properties

Know all about Peridotite and Siltstone properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Siltstone belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Siltstone is Clastic. Peridotite appears Rough and Shiny and Siltstone appears Rough. The luster of Peridotite is shiny while that of Siltstone is dull. Peridotite is available in dark greenish - grey colors whereas Siltstone is available in brown, red, reddish brown colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Siltstone are raw material for the manufacture of mortar, soil conditioner.
