Dunite vs Basanite  Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Dunite and Basanite  Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Dunite vs Basanite  information and Dunite vs Basanite  characteristics in the upcoming sections.

Dunite 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. Dunite vs Basanite  characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Basanite . Learn more about Dunite vs Basanite  in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Basanite  include Decorative aggregates and Homes.
