The Geologic Oddity in Australia where the Mantle is Exposed; Macquarie Island

In a section of Australia, the mantle is being actively exposed on the surface at this very moment. And no, I am not referring to a volcanic eruption. Rather, I am referring to Macquarie island, which hosts a colorful assortment of primarily green minerals which include olivine (whose gem form is known as peridot), serpentine, and zoisite. This video will explain how a piece of the Earth&mantle ended up above sea level.
