Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Coal vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Suevite. Learn more about Coal vs Suevite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Coal and Suevite, 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 Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Coal and Suevite
Here you can know more about Coal and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Suevite 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 Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Suevite, 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, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Coal is Veined or Pebbled and that of Suevite is Banded. Properties of rock is another aspect for Coal vs Suevite. The hardness of Coal is 1-1.5 and that of Suevite is 5.5. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Suevite is 0.92 kJ/Kg K. 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 Suevite is heat resistant.
