Although much attention has been given to mechanisms that drive variations in mantle fO2 between tectonic settings and to comparisons of fO2 between modern rocks and ancient-mantle-derived rocks, comparatively little has been done to understand the origins of the high variability in fO2 recorded by peridotites from modern mid-ocean ridge settings. Here we report the petrography and geochemistry of peridotites from the Gakkel Ridge and East Pacific Rise (EPR), including 16 new high-precision determinations of fO2. Refractory peridotites from the Gakkel Ridge record fO2 more than four orders of magnitude below the mantle average. With thermodynamic and mineral partitioning modelling, we show that excursions to ultralow fO2 can be produced by large degrees of melting at high potential temperature (Tp), beginning in the garnet field and continuing into the spinel field—conditions met during the generation of ancient komatiites but not modern basalts. This does not mean that ambient convecting upper mantle had a lower ferric to ferrous ratio in Archaean times than today nor that modern melting in the garnet field at hotspots produce reduced magmas. Instead, it implies that rafts of ancient, refractory, ultrareduced mantle continue to circulate in the modern mantle while contributing little to modern ridge volcanism.心里美滋滋不只是蔡婆婆的个人感受而是住进照料中心大部分老人的感受她们需要被人关怀、被人照顾需要更多交流和互动在这里会尽可能被满足——一声声暖意洋洋的阿嬷足够他们在自己的情感簿上给照料中心划出一个又一个钩
