Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

Evaporite vs Amphibolite 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 Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Amphibolite. Learn more about Evaporite vs Amphibolite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Evaporite and Amphibolite, 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 Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.
More about Evaporite and Amphibolite
Here you can know more about Evaporite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Amphibolite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Amphibolite, 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, Amphibolite is available in black, brown, green, grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Amphibolite is Foliated. Properties of rock is another aspect for Evaporite vs Amphibolite. The hardness of Evaporite is 2-3 and that of Amphibolite is 6-7. The types of Evaporite are Not Available whereas types of Amphibolite are Hornblendite. 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 Amphibolite is white to grey. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Amphibolite is Not Available. 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 Amphibolite is heat resistant, pressure resistant, wear resistant.
