Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Basanite 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. Basanite vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Dolomite. Learn more about Basanite vs Dolomite in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Basanite and Dolomite, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points 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 Basanite and Dolomite
Here you can know more about Basanite and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Dolomite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase 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 Basanite vs Dolomite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Basanite is Glassy or Pearly and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Basanite vs Dolomite. The hardness of Basanite is 7 and that of Dolomite is 3.5-4. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite 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 Basanite and Dolomite is white. The specific heat capacity of Basanite is 0.74 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Dolomite is heat resistant, pressure resistant, wear resistant.
