Glasses quenched from relatively undegassed ocean island magmas erupted from volcanoes at Iceland, Hawaii, the Canary Islands, and Erebus have elevated Fe³âº/∑Fe ratios compared to glasses quenched from mid-ocean ridge basalts. This has been ascribed to elevated fOâ‚‚ of their mantle sources, pla...
