Description
The low Re abundance in arc-type volcanic rocks characterized by high 187Os/188Os ratios is an unsolved puzzle of the 187Re-187OS isotope system, leaving a significant gap in our understanding of the evolution of the upper mantle-continental crust system. Here we report new observations of high Re concentrations in fresh, submarine-erupted-i.e., relatively undegassed-island arc-like volcanic glasses dredged from the eastern Manus Basin, offshore Papua New Guinea. These observations, together...[Show more]
