Archaeological Significance
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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Talc carbonate and Jasperoid Properties
Know all about Talc carbonate and Jasperoid 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 Jasperoid belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Jasperoid is Earthy. Talc carbonate appears Soft and Jasperoid appears Glassy or Pearly. The luster of Talc carbonate is pearly while that of Jasperoid is vitreous and pearly. Talc carbonate is available in grey, white colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
