Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

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.

More about Talc carbonate and Metapelite
Here you can know more about Talc carbonate and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Metapelite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Metapelite, 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, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Talc carbonate is Soft and that of Metapelite is Banded. Properties of rock is another aspect for Talc carbonate vs Metapelite. The hardness of Talc carbonate is 1-2 and that of Metapelite is 5-6. The types of Talc carbonate are Not Available whereas types of Metapelite are Not Available. 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 Metapelite is unknown. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
