Cataclasite and Schist


Schist and Cataclasite


Definition

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   
Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation

Formation

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.   
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

All about Cataclasite and Schist Properties

Know all about Cataclasite and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite and Schist belong to Metamorphic Rocks.Texture of Cataclasite is Clastic whereas that of Schist is Foliated, Platy. Cataclasite appears Dull and Banded and Schist appears Layered and Shiny. The luster of Cataclasite is vitreous while that of Schist is shiny. Cataclasite is available in brown, green, white, yellow colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Schist are used in aquariums, writing slates.
