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.
Harzburgite 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 Harzburgite Properties
Know all about Talc carbonate and Harzburgite 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 Harzburgite belongs to Igneous Rocks.Texture of Talc carbonate is Very Soft whereas that of Harzburgite is Phaneritic. Talc carbonate appears Soft and Harzburgite appears Rough and Shiny. The luster of Talc carbonate is pearly while that of Harzburgite is shiny. Talc carbonate is available in colourless, grey, white colors whereas Harzburgite is available in dark greenish - grey colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Harzburgite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
