Formation

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

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

All about Evaporite and Anorthosite Properties

Know all about Evaporite and Anorthosite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Anorthosite belongs to Igneous Rocks.Texture of Evaporite is Earthy whereas that of Anorthosite is Foliated, Glassy. Evaporite appears Glassy, Vesicular and Foilated and Anorthosite appears Layered, Banded, Veined and Shiny. The luster of Evaporite is subvitreous to dull while that of Anorthosite is pearly to subvitreous. Evaporite is available in green, grey, silver, white colors whereas Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white 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 Anorthosite are creating artwork, curling.
