5 Formation

5.1 Formation

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

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

5.2 Composition

5.2.1 Mineral Content

All about Evaporite and Blueschist Properties

Know all about Evaporite and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite belongs to Sedimentary Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Evaporite is Earthy whereas that of Blueschist is Foliated. Evaporite appears Glassy, Vesicular and Foilated and Blueschist appears Dull and Banded. The luster of Evaporite is subvitreous to dull while that of Blueschist is dull. Evaporite is available in colourless, green, grey, silver, white colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue 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 Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
