Definition
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.
  
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.
  
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Luxullianite vs Dolomite 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. Luxullianite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Luxullianite and Properties of Dolomite. Learn more about Luxullianite vs Dolomite in the next section. The interior uses of Luxullianite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Luxullianite and Dolomite, they have various applications in construction industry. The uses of Luxullianite in construction industry include As dimension stone and that of Dolomite 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.
More about Luxullianite and Dolomite
Here you can know more about Luxullianite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Luxullianite and Dolomite consists of mineral content and compound content. The mineral content of Luxullianite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Luxullianite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Luxullianite is available in black, grey, orange, pink, white colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Luxullianite is Veined or Pebbled and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Luxullianite vs Dolomite. The hardness of Luxullianite is 6-7 and that of Dolomite is 3.5-4. The types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite whereas types of Dolomite are Boninite and Jasperoid. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Luxullianite and Dolomite is white. The specific heat capacity of Luxullianite is 0.79 kJ/Kg K and that of Dolomite 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.Luxullianite is heat resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
