Pyrolite and Evaporite

Pyrolite

Evaporite

Definition

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Formation

Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Pyrolite and Evaporite Properties

Know all about Pyrolite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Pyrolite is Phaneritic whereas that of Evaporite is Earthy. Pyrolite appears Rough and Shiny and Evaporite appears Glassy, Vesicular and Foilated. The luster of Pyrolite is shiny while that of Evaporite is subvitreous to dull. Pyrolite is available in dark greenish - grey colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
