Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Lherzolite and Talc carbonate Properties
Know all about Lherzolite and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Lherzolite is Grenue whereas that of Talc carbonate is Very Soft. Lherzolite appears Glassy, Vesicular and Foilated and Talc carbonate appears Soft. The luster of Lherzolite is subvitreous to dull while that of Talc carbonate is pearly. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Talc carbonate is available in colourless, grey, white colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Talc carbonate are manufacturing of baby powder.
