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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Jasperoid and Diamictite Properties
Know all about Jasperoid and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid and Diamictite belong to Sedimentary Rocks.Texture of Jasperoid is Earthy whereas that of Diamictite is Clastic. Jasperoid appears Glassy or Pearly and Diamictite appears Banded. The luster of Jasperoid is vitreous and pearly while that of Diamictite is grainy, pearly and vitreous. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
