Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.
Felsite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Talc carbonate vs Felsite 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 Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Talc carbonate and Properties of Felsite. Learn more about Talc carbonate vs Felsite in the next section. The interior uses of Talc carbonate include Decorative aggregates and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Talc carbonate and Felsite, they have various applications in construction industry. The uses of Talc carbonate in construction industry include Source of calcium and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Talc carbonate and Felsite
Here you can know more about Talc carbonate and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Felsite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Metamorphic Rocks. When we have to compare Talc carbonate vs Felsite, 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, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Talc carbonate is Soft and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Talc carbonate vs Felsite. The hardness of Talc carbonate is 1-2 and that of Felsite is 5-5.5. The types of Talc carbonate are Not Available whereas types of Felsite 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 Felsite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Felsite is 0.92 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 Felsite is heat resistant, impact resistant.
