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.
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 vs Coal 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. Breccia vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Breccia and Properties of Coal. Learn more about Breccia vs Coal in the next section. The interior uses of Breccia include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Breccia and Coal, they have various applications in construction industry. The uses of Breccia in construction industry include As dimension stone, Construction aggregate, Landscaping, Roadstone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Breccia and Coal
Here you can know more about Breccia and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Breccia and Coal consists of mineral content and compound content. The mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica and 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. You can also check out the list of all Sedimentary Rocks. When we have to compare Breccia vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Breccia is Layered, Banded, Veined and Shiny and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Breccia vs Coal. The hardness of Breccia is 7 and that of Coal is 1-1.5. The types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Breccia is white while that of Coal is black. The specific heat capacity of Breccia is Not Available and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Breccia is heat resistant, impact resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
