Definition
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
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.

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