Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
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.

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From the village of Luxulyan in Cornwall, England, where this variety of granite is found

Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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 vs Luxullianite 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 Luxullianite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Luxullianite. Learn more about Dolomite vs Luxullianite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Luxullianite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Dolomite and Luxullianite, 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 Luxullianite include As dimension stone.
More about Dolomite and Luxullianite
Here you can know more about Dolomite and Luxullianite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Luxullianite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Luxullianite 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 Luxullianite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, green, grey, pink, white colors whereas, Luxullianite is available in black, grey, orange, pink, white colors. Appearance of Dolomite is Glassy or Pearly and that of Luxullianite is Veined or Pebbled. Properties of rock is another aspect for Dolomite vs Luxullianite. The hardness of Dolomite is 3.5-4 and that of Luxullianite is 6-7. The types of Dolomite are Boninite and Jasperoid whereas types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Luxullianite is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Luxullianite 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 Luxullianite is heat resistant, wear resistant.
