1.1 Definition

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

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

1.3 Etymology

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

From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

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.

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Lherzolite and Dolomite Properties

Know all about Lherzolite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Lherzolite is Grenue whereas that of Dolomite is Earthy. Lherzolite appears Glassy, Vesicular and Foilated and Dolomite appears Glassy or Pearly. The luster of Lherzolite is subvitreous to dull while that of Dolomite is vitreous and pearly. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
