Formation

Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.   
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 Appinite and Jasperoid Properties

Know all about Appinite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Appinite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Appinite is Porphyritic whereas that of Jasperoid is Earthy. Appinite appears Dull, Banded and Foilated and Jasperoid appears Glassy or Pearly. The luster of Appinite is subvitreous to dull while that of Jasperoid is vitreous and pearly. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Appinite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner 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).
