Formation

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.

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

All about Anorthosite and Evaporite Properties

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