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
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts

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.
Rhomb-porphyry 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.

All about Cataclasite and Rhomb Porphyry Properties
Know all about Cataclasite and Rhomb Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Rhomb Porphyry belongs to Igneous Rocks.Texture of Cataclasite is Clastic whereas that of Rhomb Porphyry is Aphanitic to Porphyritic. Cataclasite appears Dull and Banded and Rhomb Porphyry appears Rough. The luster of Cataclasite is vitreous while that of Rhomb Porphyry is subvitreous to dull. Cataclasite is available in brown, green, white, yellow colors whereas Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Rhomb Porphyry are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
