Definition

Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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

Shoshonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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 Shoshonite and Cataclasite Properties

Know all about Shoshonite and Cataclasite properties here. All properties of rocks are important as they define the type of rock and its application. Shoshonite belongs to Igneous Rocks while Cataclasite belongs to Metamorphic Rocks.Texture of Shoshonite is Porphyritic whereas that of Cataclasite is Clastic. Shoshonite appears Dull and Cataclasite appears Dull and Banded. The luster of Shoshonite is dull while that of Cataclasite is vitreous. Shoshonite is available in brown- black, dark brown colors whereas Cataclasite is available in brown, green, white, yellow colors. The commercial uses of Shoshonite are cemetery markers, creating artwork and that of Cataclasite are commemorative tablets, creating artwork.
