The volcanic rock basalt is formed when magnesium and ironrich lava which is called 'mafic lava' gets cooled off rapidly. As reported by The Print, 90 percent of the Earth's volcanic rock is basaltic in nature. This rock has formed large areas of land in regions like Iceland, Hawaii, and India's Deccan Traps.
