Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Talc carbonate 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. Talc carbonate vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Coal. Learn more about Talc carbonate vs Coal in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Talc carbonate and Coal, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Talc carbonate and Coal
Here you can know more about Talc carbonate and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Coal consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium 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 Metamorphic Rocks. When we have to compare Talc carbonate vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in colourless, grey, white colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Talc carbonate is Soft and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Talc carbonate vs Coal. The hardness of Talc carbonate is 1-2 and that of Coal is 1-1.5. The types of Talc carbonate are Not Available 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 Talc carbonate is white while that of Coal is black. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K 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.Talc carbonate is heat resistant, wear resistant whereas Coal is heat resistant.
