Mudstone and Peridotite


Definition

Definition
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle   
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

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.   
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

All about Peridotite and Mudstone Properties

Know all about Peridotite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Peridotite belongs to Igneous Rocks while Mudstone belongs to Sedimentary Rocks.Texture of Peridotite is Phaneritic whereas that of Mudstone is Clastic. Peridotite appears Rough and Shiny and Mudstone appears Rough and Dull. The luster of Peridotite is shiny while that of Mudstone is dull. Peridotite is available in dark greenish - grey colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. The commercial uses of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Mudstone are creating artwork, pottery.
