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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

Talc carbonate vs Soapstone 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 Soapstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Soapstone. Learn more about Talc carbonate vs Soapstone in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Soapstone, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Soapstone include Manufacture of magnesium and dolomite refractories.
More about Talc carbonate and Soapstone
Here you can know more about Talc carbonate and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Soapstone consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Soapstone, 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, Soapstone is available in black, black to grey, green, grey colors. Appearance of Talc carbonate is Soft and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Talc carbonate vs Soapstone. The hardness of Talc carbonate is 1-2 and that of Soapstone is 1. The types of Talc carbonate are Not Available whereas types of Soapstone 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 Soapstone is black. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Soapstone is 0.88 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 Soapstone is heat resistant, pressure resistant.
