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.
  
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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