Picrite vs Dunite

Picrite 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 Picrite and Dunite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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.
