Formation

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.   
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Jasperoid and Latite Properties

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