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
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Origin
Swiss Alps, Europe

Etymology
From the Italian word cataclasi
From 17th century, because of its greasy feel and use like a soap

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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

All about Cataclasite and Soapstone Properties
Know all about Cataclasite and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite and Soapstone belong to Metamorphic Rocks.Texture of Cataclasite is Clastic whereas that of Soapstone is Polished. Cataclasite appears Dull and Banded and Soapstone appears Dull, Banded and Foilated. The luster of Cataclasite is vitreous while that of Soapstone is greasy. Cataclasite is available in brown, green, white, yellow colors whereas Soapstone is available in black, black to grey, green, grey colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Soapstone are cemetery markers, creating artwork, gemstone, jewelry, manufacture of soap, solvents, dyes, plastics and fibres, production of lime, source of magnesia (mgo).
