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.
Sovites are formed due to low degrees of partial melting of rocks.

Coal vs Sovite 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 Sovite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Sovite. Learn more about Coal vs Sovite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Sovite include Decorative aggregates and Homes. Due to some exceptional properties of Coal and Sovite, 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 Sovite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Unknown, Unknown.
More about Coal and Sovite
Here you can know more about Coal and Sovite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Sovite 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 Sovite includes Ancylite, Apatite, Barite, Fluorite, Magnetite, Natrolite, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Sovite, 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, Sovite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Coal is Veined or Pebbled and that of Sovite is Dull, Banded and Foilated. Properties of rock is another aspect for Coal vs Sovite. The hardness of Coal is 1-1.5 and that of Sovite is 3. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Sovite are Not Available. 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 Sovite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Sovite 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 Sovite is heat resistant, pressure resistant.
