Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
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 Limestone and Jasperoid Properties
Know all about Limestone and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Jasperoid belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Jasperoid is Earthy. Limestone appears Rough and Banded and Jasperoid appears Glassy or Pearly. The luster of Limestone is dull to pearly while that of Jasperoid is vitreous and pearly. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses 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 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).
