Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
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
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
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.

Evaporite 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. Evaporite vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Felsite. Learn more about Evaporite vs Felsite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Evaporite and Felsite, they have various applications in construction industry. The uses of Evaporite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Evaporite and Felsite
Here you can know more about Evaporite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Felsite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in colourless, green, grey, silver, white colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Evaporite vs Felsite. The hardness of Evaporite is 2-3 and that of Felsite is 5-5.5. The types of Evaporite 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 Evaporite and Felsite is white. The specific heat capacity of Evaporite 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.Evaporite is heat resistant, pressure resistant whereas Felsite is heat resistant, impact resistant.
