Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Troctolite 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 Troctolite 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 Troctolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Troctolite. Learn more about Evaporite vs Troctolite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Evaporite and Troctolite, 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 Troctolite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Evaporite and Troctolite
Here you can know more about Evaporite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Troctolite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Troctolite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Troctolite is available in dark grey to black colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Evaporite vs Troctolite. The hardness of Evaporite is 2-3 and that of Troctolite is 7. The types of Evaporite are Sedimentary rock whereas types of Troctolite are Ultramafic rock. 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 Troctolite is black. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Troctolite is 0.84 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 Troctolite is impact resistant, pressure resistant, wear resistant.
