Definition
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.

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