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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

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