Formation

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

Felsite vs Evaporite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Felsite and Evaporite Reserves. 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. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Felsite vs Evaporite information and Felsite vs Evaporite characteristics in the upcoming sections.

Felsite vs Evaporite 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 Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Evaporite. Learn more about Felsite vs Evaporite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Felsite and Evaporite, 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 Evaporite 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.

More about Felsite and Evaporite

Here you can know more about Felsite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Evaporite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Evaporite, 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, Evaporite is available in green, grey, silver, white colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Felsite vs Evaporite. The hardness of Felsite is 5-5.5 and that of Evaporite is 2-3. The types of Felsite are Igneous rock whereas types of Evaporite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite and Evaporite is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Evaporite 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 Evaporite is heat resistant, pressure resistant.
