Definition
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Rhomb Porphyry and Serpentinite
Here you can know more about Rhomb Porphyry and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhomb Porphyry and Serpentinite consists of mineral content and compound content. The mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Rhomb Porphyry vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Rhomb Porphyry is available in black, brown, colourless, green, grey, pink, white colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Rhomb Porphyry is Rough and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Rhomb Porphyry vs Serpentinite. The hardness of Rhomb Porphyry is 5-5.5 and that of Serpentinite is 3-5. The types of Rhomb Porphyry are Not Available whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhomb Porphyry is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Rhomb Porphyry is 0.92 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Rhomb Porphyry is heat resistant, pressure resistant whereas Serpentinite is heat resistant.
