Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Evaporite and Lamprophyre Properties
Know all about Evaporite and Lamprophyre properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Lamprophyre belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Lamprophyre is Porphyritic. Evaporite appears Glassy, Vesicular and Foilated and Lamprophyre appears Dull, Banded and Foilated. The luster of Evaporite and Lamprophyre is subvitreous to dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, 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 Lamprophyre are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
