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.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Jasperoid and Limestone Properties

Know all about Jasperoid and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid and Limestone belong to Sedimentary Rocks.Texture of Jasperoid is Earthy whereas that of Limestone is Clastic or Non-Clastic. Jasperoid appears Glassy or Pearly and Limestone appears Rough and Banded. The luster of Jasperoid is vitreous and pearly while that of Limestone is dull to pearly. Jasperoid is available in black, brown, green, grey, pink, white colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow 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 Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
