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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Jasperoid and Laterite Properties
Know all about Jasperoid and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid and Laterite belong to Sedimentary Rocks.Texture of Jasperoid is Earthy whereas that of Laterite is Earthy, Massive, Porphyritic. Jasperoid appears Glassy or Pearly and Laterite appears Rough and Banded. The luster of Jasperoid is vitreous and pearly while that of Laterite is dull. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Laterite is available in brown, buff, red 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 Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
