Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Talc carbonate vs Limestone 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 Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Limestone. Learn more about Talc carbonate vs Limestone in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Talc carbonate and Limestone, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.
More about Talc carbonate and Limestone
Here you can know more about Talc carbonate and Limestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Limestone consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all . When we have to compare Talc carbonate vs Limestone, 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, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Talc carbonate is Soft and that of Limestone is Rough and Banded. Properties of rock is another aspect for Talc carbonate vs Limestone. The hardness of Talc carbonate is 1-2 and that of Limestone is 3-4. The types of Talc carbonate are Not Available whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Limestone is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Limestone is 0.91 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 Limestone is pressure resistant.
