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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

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