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.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Talc carbonate and Anorthosite Properties
Know all about Talc carbonate and Anorthosite 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 Anorthosite belongs to Igneous Rocks.Texture of Talc carbonate is Very Soft whereas that of Anorthosite is Foliated, Glassy. Talc carbonate appears Soft and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Talc carbonate is pearly while that of Anorthosite is pearly to subvitreous. Talc carbonate is available in colourless, grey, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Anorthosite are creating artwork, curling.
