Mantle xenolith

  • Exhibition Text

    • Fragments from the upper mantle are sometimes transported to the surface by erupting lava. This sample of basalt lava contains two types of mantle rocks. The green one is a lherzolite, a rock made up of olivine (pale green) and the pyroxene minerals enstatite (black) and diopside (bottle green). The black fragments are pyroxenites, composed mostly of of enstatite. These fragments probably originate from about 60 kilometers in depth.
