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.

All about Evaporite and Diabase Properties

Know all about Evaporite and Diabase properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Diabase belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Diabase is Aphanitic, Granular. Evaporite appears Glassy, Vesicular and Foilated and Diabase appears Vesicular. The luster of Evaporite is subvitreous to dull while that of Diabase is . Evaporite is available in green, grey, silver, white colors whereas Diabase is available in dark grey to black colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
