Granulite vs Dunite 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 Granulite and Dunite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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 Granulite vs Dunite information and Granulite vs Dunite characteristics in the upcoming sections.

Granulite vs Dunite 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. Granulite vs Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Dunite. Learn more about Granulite vs Dunite in the next section.
