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
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Cataclasite and Boninite Properties
Know all about Cataclasite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Boninite belongs to Igneous Rocks.Texture of Cataclasite is Clastic whereas that of Boninite is Aphanitic to Porphyritic. Cataclasite appears Dull and Banded and Boninite appears Dull and Soft. The luster of Cataclasite and Boninite is vitreous. Cataclasite is available in brown, green, white, yellow colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
