Abstract Glasses quenched from relatively undegassed ocean island magmas erupted from volcanoes at Iceland, Hawaii, the Canary Islands, and Erebus have elevated Fe 3+ /∑Fe ratios compared to glasses quenched from mid-ocean ridge basalts. This has been ascribed to elevated f O 2 of their mantle sourc...
