Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Evaporite vs Diabase 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 Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Diabase. Learn more about Evaporite vs Diabase in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Evaporite and Diabase, 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 Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Evaporite and Diabase
Here you can know more about Evaporite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Diabase consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Diabase is Vesicular. Properties of rock is another aspect for Evaporite vs Diabase. The hardness of Evaporite is 2-3 and that of Diabase is 7. The types of Evaporite are Not Available whereas types of Diabase 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 Diabase is black. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Diabase 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
