Definition
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
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.

All about Ganister and Breccia Properties
Know all about Ganister and Breccia properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Breccia belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Breccia is Brecciated, Clastic. Ganister appears Rough and Breccia appears Layered, Banded, Veined and Shiny. The luster of Ganister is dull while that of Breccia is dull to pearly. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Breccia are creating artwork, gemstone, jewelry.
