Archaeological Significance
Formation
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.
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.

All about Jasperoid and Talc carbonate Properties
Know all about Jasperoid and Talc carbonate properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Talc carbonate belongs to Metamorphic Rocks.Texture of Jasperoid is Earthy whereas that of Talc carbonate is Very Soft. Jasperoid appears Glassy or Pearly and Talc carbonate appears Soft. The luster of Jasperoid is vitreous and pearly while that of Talc carbonate is pearly. Jasperoid and Talc carbonate are available in black, brown, green, grey, pink, white colors. The commercial uses 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) and that of Talc carbonate are manufacturing of baby powder.
