Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
  
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
  
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

Diorite vs Marble 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. Diorite vs Marble characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diorite and Properties of Marble. Learn more about Diorite vs Marble in the next section. The interior uses of Diorite include Decorative aggregates and Interior decoration whereas the interior uses of Marble include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Diorite and Marble, they have various applications in construction industry. The uses of Diorite in construction industry include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate and that of Marble include As dimension stone.
More about Diorite and Marble
Here you can know more about Diorite and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Marble consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Diorite vs Marble, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Diorite is Shiny and that of Marble is Veined and Shiny. Properties of rock is another aspect for Diorite vs Marble. The hardness of Diorite is 6-7 and that of Marble is 3-4. The types of Diorite are Not Available whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diorite is bluish black while that of Marble is white. The specific heat capacity of Diorite is Not Available and that of Marble is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diorite is heat resistant, pressure resistant, wear resistant whereas Marble is heat resistant.
