Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

Dolomite 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. Dolomite vs Granodiorite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Granodiorite. Learn more about Dolomite vs Granodiorite in the next section. The interior uses of Dolomite 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 Dolomite and Granodiorite, they have various applications in construction industry. The uses of Dolomite 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, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Granodiorite include As dimension stone.
More about Dolomite and Granodiorite
Here you can know more about Dolomite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Granodiorite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Sedimentary Rocks. When we have to compare Dolomite vs Granodiorite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Dolomite is Glassy or Pearly and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Dolomite vs Granodiorite. The hardness of Dolomite is 3.5-4 and that of Granodiorite is 6. The types of Dolomite are Boninite and Jasperoid 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 Dolomite and Granodiorite is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Granodiorite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Granodiorite is heat resistant, wear resistant.
