Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

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.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

All about Talc carbonate and Slate Properties
Know all about Talc carbonate and Slate properties here. All properties of rocks are important as they define the type of rock and its application. Talc carbonate and Slate belong to Metamorphic Rocks.Texture of Talc carbonate is Very Soft whereas that of Slate is Foliated. Talc carbonate appears Soft and Slate appears Dull. The luster of Talc carbonate is pearly while that of Slate is dull. Talc carbonate is available in grey, white colors whereas Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue colors. The commercial uses of Talc carbonate are manufacturing of baby powder and that of Slate are blackboards, commemorative tablets, laboratory bench tops, standard material for the bed of billiard table, standard material for the beds of pool and snooker table, tombstones, used in aquariums, writing slates.
