Formation
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
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 Breccia and Jasperoid Properties
Know all about Breccia and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Breccia and Jasperoid belong to Sedimentary Rocks.Texture of Breccia is Brecciated, Clastic whereas that of Jasperoid is Earthy. Breccia appears Layered, Banded, Veined and Shiny and Jasperoid appears Glassy or Pearly. The luster of Breccia is dull to pearly while that of Jasperoid is vitreous and pearly. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Breccia are creating artwork, gemstone, jewelry 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).
