Oxygen thermobarometry of abyssal spinel peridotites:the redox state and C-O-H volatile composition of the Earth's sub-oceanic upper mantle

We have applied the spinel peridotite oxygen barometer to abyssal spinel peridotites from the mid-Atlantic, central Indian, southwest Indian and American-Antarctic ocean ridge systems. The results indicate that the oxygen fugacity (f O2 ) of the suboceanic mantle is on average 0.9 ± 0.7 (n = 33; ± 1...
