Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Tachylite 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 Tachylite 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 Tachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Tachylite. Learn more about Evaporite vs Tachylite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Tachylite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Evaporite and Tachylite, 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 Tachylite include Cutting tool, Knives, Landscaping, Scrapers.
More about Evaporite and Tachylite
Here you can know more about Evaporite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Tachylite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Tachylite, 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, Tachylite is available in black, dark brown colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Tachylite is Glassy. Properties of rock is another aspect for Evaporite vs Tachylite. The hardness of Evaporite is 2-3 and that of Tachylite is 5.5. The types of Evaporite are Not Available whereas types of Tachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite is white while that of Tachylite is vermilion. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Tachylite is 0.56 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 Tachylite is heat resistant, impact resistant, wear resistant.
