Definition

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

Formation

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

Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

All about Evaporite and Mudstone Properties

Know all about Evaporite and Mudstone properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Mudstone belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Mudstone is Clastic. Evaporite appears Glassy, Vesicular and Foilated and Mudstone appears Rough and Dull. The luster of Evaporite is subvitreous to dull while that of Mudstone is dull. Evaporite is available in green, grey, silver, white colors whereas Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow 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 Mudstone are creating artwork, pottery.
