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.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

All about Talc carbonate and Anthracite Properties
Know all about Talc carbonate and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Talc carbonate and Anthracite belong to Metamorphic Rocks.Texture of Talc carbonate is Very Soft whereas that of Anthracite is Amorphous, Glassy. Talc carbonate appears Soft and Anthracite appears Veined or Pebbled. The luster of Talc carbonate is pearly while that of Anthracite is shiny. Talc carbonate is available in grey, white colors whereas Anthracite 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 Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
