Definition

Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

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

Formation

Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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

All about Cataclasite and Evaporite Properties

Know all about Cataclasite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Cataclasite is Clastic whereas that of Evaporite is Earthy. Cataclasite appears Dull and Banded and Evaporite appears Glassy, Vesicular and Foilated. The luster of Cataclasite is vitreous while that of Evaporite is subvitreous to dull. Cataclasite is available in brown, green, white, yellow colors whereas Evaporite is available in green, grey, silver, white colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
