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

Dolomite vs Basanite 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 Basanite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Basanite . Learn more about Dolomite vs Basanite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Basanite include Decorative aggregates and Homes. Due to some exceptional properties of Dolomite and Basanite , 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 Basanite include Arrowheads, Construction aggregate, Cutting tool, Spear points.
More about Dolomite and Basanite
Here you can know more about Dolomite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Basanite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Dolomite is Glassy or Pearly and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Dolomite vs Basanite . The hardness of Dolomite is 3.5-4 and that of Basanite is 7. The types of Dolomite are Boninite and Jasperoid whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Basanite is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
