Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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.

Conglomerate vs Breccia Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Conglomerate vs Breccia characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Conglomerate and Properties of Breccia. Learn more about Conglomerate vs Breccia in the next section. The interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes whereas the interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Conglomerate and Breccia, they have various applications in construction industry. The uses of Conglomerate in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone and that of Breccia include As dimension stone, Construction aggregate, Landscaping, Roadstone.
More about Conglomerate and Breccia
Here you can know more about Conglomerate and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Conglomerate and Breccia consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt and mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Conglomerate vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. 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. Appearance of Conglomerate is Shiny and Rounded and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Conglomerate vs Breccia. The hardness of Conglomerate is 2-3 and that of Breccia is 7. The types of Conglomerate are Orthoconglomerate and Paraconglomerate whereas types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Conglomerate and Breccia is white. The specific heat capacity of Conglomerate is 0.92 kJ/Kg K and that of Breccia is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Conglomerate is heat resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
