Evaporite and Cataclasite


Cataclasite and Evaporite


Definition

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

Formation

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

All about Evaporite and Cataclasite Properties

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