Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
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.

Coal 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. Coal vs Breccia characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Breccia. Learn more about Coal vs Breccia in the next section. The interior uses of Coal include Not yet used 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 Coal and Breccia, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Breccia include As dimension stone, Construction aggregate, Landscaping, Roadstone.
More about Coal and Breccia
Here you can know more about Coal and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Breccia consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon 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 Coal vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Coal vs Breccia. The hardness of Coal is 1-1.5 and that of Breccia is 7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite 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 Coal is black while that of Breccia is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Breccia is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
