Definition
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

All about Rhomb Porphyry and Marble Properties
Know all about Rhomb Porphyry and Marble 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 Marble belongs to Metamorphic Rocks.Texture of Rhomb Porphyry is Aphanitic to Porphyritic whereas that of Marble is Granular. Rhomb Porphyry appears Rough and Marble appears Veined and Shiny. The luster of Rhomb Porphyry is subvitreous to dull while that of Marble is dull to pearly to subvitreous. Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors whereas Marble is available in black, blue, brown, grey, pink, white 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 Marble are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
