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

Archaeological Significance
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.

All about Talc carbonate and Coal Properties
Know all about Talc carbonate and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Talc carbonate belongs to Metamorphic Rocks while Coal belongs to Sedimentary Rocks.Texture of Talc carbonate is Very Soft whereas that of Coal is Amorphous, Glassy. Talc carbonate appears Soft and Coal appears Veined or Pebbled. The luster of Talc carbonate is pearly while that of Coal is dull to vitreous to submetallic. Talc carbonate is available in grey, white colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
