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.
  
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Rhomb Porphyry vs Granodiorite 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. Rhomb Porphyry vs Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhomb Porphyry and Properties of Granodiorite. Learn more about Rhomb Porphyry vs Granodiorite in the next section. The interior uses of Rhomb Porphyry include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Granodiorite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration and Stair treads. Due to some exceptional properties of Rhomb Porphyry and Granodiorite, they have various applications in construction industry. The uses of Rhomb Porphyry in construction industry 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 and that of Granodiorite include As dimension stone.
More about Rhomb Porphyry and Granodiorite
Here you can know more about Rhomb Porphyry and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhomb Porphyry and Granodiorite consists of mineral content and compound content. The mineral content of Rhomb Porphyry includes Alkali feldspar, Biotite, Plagioclase, Pyroxene and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Rhomb Porphyry vs Granodiorite, 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, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Rhomb Porphyry is Rough and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Rhomb Porphyry vs Granodiorite. The hardness of Rhomb Porphyry is 5-5.5 and that of Granodiorite is 6. The types of Rhomb Porphyry are Not Available whereas types of Granodiorite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhomb Porphyry and Granodiorite is white. The specific heat capacity of Rhomb Porphyry is 0.92 kJ/Kg K and that of Granodiorite is 0.79 kJ/Kg K.
