Rhomb Porphyry and Cataclasite


Cataclasite and Rhomb Porphyry


Definition

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

Formation
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.   
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 Rhomb Porphyry and Cataclasite Properties

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