Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Etymology
From a sediment left after the evaporation
From Late Latin Basaltes (variant of basanites ), very hard stone, which was imported from Ancient Greek Basanites

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Evaporite and Basalt Properties
Know all about Evaporite and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Basalt belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Evaporite appears Glassy, Vesicular and Foilated and Basalt appears Dull and Soft. The luster of Evaporite is subvitreous to dull while that of Basalt is . Evaporite is available in green, grey, silver, white colors whereas Basalt is available in black, brown, light to dark grey 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 Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
