Image of the Week: Studying Oman’s Samail Ophiolite

Peter Kelemen

In the desert nation of Oman, Lamont-Doherty Earth Observatory geochemist Peter Kelemen (left) and his daughter Sarah investigate a peridotite outcrop in the Samail Ophiolite, a mass of rock from Earth’s mantle thrust to the surface through a glitch in the normal subduction process. Recently, there has been a surge in interest in ophiolites, as scientists have recognized that they naturally take up and store large amounts of carbon dioxide, and thus play a previously unrecognized role in regulating global climate. Kelemen and his colleagues are exploring how this process could be sped up and used to store some of the excess carbon dioxide produced by human activities.
