Definition
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'.
Rhomb-porphyry is a porphyritic igneous rock with abundant wedge or lens shaped anorthoclase or feldspar phenocrysts

Archaeological Significance
Formation
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.
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.

Serpentinite vs Rhomb Porphyry Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Serpentinite vs Rhomb Porphyry characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Rhomb Porphyry. Learn more about Serpentinite vs Rhomb Porphyry in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Rhomb Porphyry include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Rhomb Porphyry, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Rhomb Porphyry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Serpentinite and Rhomb Porphyry
Here you can know more about Serpentinite and Rhomb Porphyry. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Rhomb Porphyry consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Rhomb Porphyry, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Rhomb Porphyry is available in black, brown, green, grey, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Rhomb Porphyry is Rough. Properties of rock is another aspect for Serpentinite vs Rhomb Porphyry. The hardness of Serpentinite is 3-5 and that of Rhomb Porphyry is 5-5.5. The types of Serpentinite are Jadeitite whereas types of Rhomb Porphyry are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Rhomb Porphyry is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Rhomb Porphyry is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Rhomb Porphyry is heat resistant, pressure resistant.
