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

All about Lamprophyre and Evaporite Properties
Know all about Lamprophyre and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Lamprophyre is Porphyritic whereas that of Evaporite is Earthy. Lamprophyre appears Dull, Banded and Foilated and Evaporite appears Glassy, Vesicular and Foilated. The luster of Lamprophyre and Evaporite is subvitreous to dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses 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) and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
