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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

Talc carbonate vs Pumice 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 Pumice characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Pumice. Learn more about Talc carbonate vs Pumice in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Talc carbonate and Pumice, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.
More about Talc carbonate and Pumice
Here you can know more about Talc carbonate and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Pumice consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Talc carbonate is Soft and that of Pumice is Vesicular. Properties of rock is another aspect for Talc carbonate vs Pumice. The hardness of Talc carbonate is 1-2 and that of Pumice is 6. The types of Talc carbonate are Not Available whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
