Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
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 Conglomerate and Rhomb Porphyry Properties
Know all about Conglomerate and Rhomb Porphyry properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Rhomb Porphyry belongs to Igneous Rocks.Texture of Conglomerate is Clastic whereas that of Rhomb Porphyry is Aphanitic to Porphyritic. Conglomerate appears Shiny and Rounded and Rhomb Porphyry appears Rough. The luster of Conglomerate is dull while that of Rhomb Porphyry is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Conglomerate are cemetery markers, in aquifers, tombstones 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).
