Formation

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

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

All about Phyllite and Evaporite Properties

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