Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Basanite and Evaporite Properties
Know all about Basanite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Evaporite is Earthy. Basanite appears Glassy or Pearly and Evaporite appears Glassy, Vesicular and Foilated. The luster of Basanite is waxy and dull while that of Evaporite is subvitreous to dull. Basanite is available in black, brown, green, grey, red, white colors whereas Evaporite is available in green, grey, silver, white colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
