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

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