Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Breccia Properties
Know all about Conglomerate and Breccia properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate and Breccia belong to Sedimentary Rocks.Texture of Conglomerate is Clastic whereas that of Breccia is Brecciated, Clastic. Conglomerate appears Shiny and Rounded and Breccia appears Layered, Banded, Veined and Shiny. The luster of Conglomerate is dull while that of Breccia is dull to pearly. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, 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 Conglomerate are cemetery markers, in aquifers, tombstones and that of Breccia are creating artwork, gemstone, jewelry.
