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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Talc carbonate vs Dunite 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 Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Dunite. Learn more about Talc carbonate vs Dunite in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Talc carbonate and Dunite, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Dunite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Talc carbonate and Dunite
Here you can know more about Talc carbonate and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Dunite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Talc carbonate is Soft and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Talc carbonate vs Dunite. The hardness of Talc carbonate is 1-2 and that of Dunite is 3.5-4. The types of Talc carbonate are Not Available whereas types of Dunite 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 Dunite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Dunite is 1.25 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 Dunite is heat resistant, pressure resistant, wear resistant.
