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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Rhomb Porphyry and Laterite Properties
Know all about Rhomb Porphyry and Laterite 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 Laterite belongs to Sedimentary Rocks.Texture of Rhomb Porphyry is Aphanitic to Porphyritic whereas that of Laterite is Earthy, Massive, Porphyritic. Rhomb Porphyry appears Rough and Laterite appears Rough and Banded. The luster of Rhomb Porphyry is subvitreous to dull while that of Laterite is dull. Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors whereas Laterite is available in brown, buff, red 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 Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
