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.   
Wehrlite 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 Wehrlite Properties

Know all about Jasperoid and Wehrlite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Wehrlite belongs to Igneous Rocks.Texture of Jasperoid is Earthy whereas that of Wehrlite is Banded. Jasperoid appears Glassy or Pearly and Wehrlite appears Rough and Banded. The luster of Jasperoid is vitreous and pearly while that of Wehrlite is metallic. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas Wehrlite is available in dark greenish - grey, green 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 Wehrlite are cemetery markers, creating artwork, gemstone, jewelry.
