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.

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 Talc carbonate and Dolomite Properties

Know all about Talc carbonate and Dolomite 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 Dolomite belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Dolomite is Earthy. Talc carbonate appears Soft and Dolomite appears Glassy or Pearly. The luster of Talc carbonate is pearly while that of Dolomite is vitreous and pearly. Talc carbonate is available in grey, white colors whereas Dolomite is available in black, brown, green, grey, pink, white colors.
