Mudstone and Lherzolite


Lherzolite and Mudstone


Definition

Definition
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   
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions

Etymology
From the English mud and stone, from low German mudde and stainaz   
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

Formation

Formation
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.   
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.

All about Mudstone and Lherzolite Properties

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