Definition
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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.

All about Rhomb Porphyry and Wehrlite Properties
Know all about Rhomb Porphyry and Wehrlite properties here. All properties of rocks are important as they define the type of rock and its application. Rhomb Porphyry and Wehrlite belong to Igneous Rocks.Texture of Rhomb Porphyry is Aphanitic to Porphyritic whereas that of Wehrlite is Banded. Rhomb Porphyry appears Rough and Wehrlite appears Rough and Banded. The luster of Rhomb Porphyry is subvitreous to dull while that of Wehrlite is metallic. Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors whereas Wehrlite is available in dark greenish - grey, green 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 Wehrlite are cemetery markers, creating artwork, gemstone, jewelry.
