Cataclasite and Suevite
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
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Cataclasite and Suevite Properties
Know all about Cataclasite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite and Suevite belong to Metamorphic Rocks.Texture of Cataclasite is Clastic whereas that of Suevite is Earthy. Cataclasite appears Dull and Banded and Suevite appears Banded. The luster of Cataclasite is vitreous while that of Suevite is earthy. Cataclasite is available in brown, green, white, yellow colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
