Definition

Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

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

Formation

Troctolite 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 Troctolite and Evaporite Properties

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