5 Formation

5.1 Formation

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.

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.

All about Siltstone and Peridotite Properties

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