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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Talc carbonate vs Chalk 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 Chalk characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Chalk. Learn more about Talc carbonate vs Chalk in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Chalk include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Chalk, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Chalk include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for manufacture of quicklime and slaked lime, Source of calcium.
More about Talc carbonate and Chalk
Here you can know more about Talc carbonate and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Chalk consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Chalk, 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, Chalk is available in grey, white, yellow colors. Appearance of Talc carbonate is Soft and that of Chalk is Soft. Properties of rock is another aspect for Talc carbonate vs Chalk. The hardness of Talc carbonate is 1-2 and that of Chalk is 1. The types of Talc carbonate are Not Available whereas types of Chalk 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 and Chalk is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
