Formation

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

Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Evaporite and Phyllite Properties

Know all about Evaporite and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Phyllite belongs to Metamorphic Rocks.Texture of Evaporite is Earthy whereas that of Phyllite is Phyllitic Sheen, Slaty. Evaporite appears Glassy, Vesicular and Foilated and Phyllite appears Crinkled or Wavy. The luster of Evaporite is subvitreous to dull while that of Phyllite is phyllitic. Evaporite is available in green, grey, silver, white colors whereas Phyllite is available in black to grey, light greenish grey 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 Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates.
