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
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Felsite vs Whiteschist 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 Whiteschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Whiteschist. Learn more about Felsite vs Whiteschist in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Whiteschist include Decorative aggregates and Interior decoration. Due to some exceptional properties of Felsite and Whiteschist, 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 Whiteschist include For road aggregate.
More about Felsite and Whiteschist
Here you can know more about Felsite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Whiteschist consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Whiteschist, 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, Whiteschist is available in colourless, green, grey, white colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Felsite vs Whiteschist. The hardness of Felsite is 5-5.5 and that of Whiteschist is 1.5. The types of Felsite are Not Available whereas types of Whiteschist 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 Whiteschist is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Whiteschist 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 Whiteschist is heat resistant.
