Definition
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Rhomb Porphyry and Diamictite Properties
Know all about Rhomb Porphyry and Diamictite 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 Diamictite belongs to Sedimentary Rocks.Texture of Rhomb Porphyry is Aphanitic to Porphyritic whereas that of Diamictite is Clastic. Rhomb Porphyry appears Rough and Diamictite appears Banded. The luster of Rhomb Porphyry is subvitreous to dull while that of Diamictite is grainy, pearly and vitreous. Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors whereas Diamictite is available in brown, buff 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 Diamictite are commemorative tablets, creating artwork, production of lime.
