Oxygen isotope (δ(18)O, Δ′(17)O) insights into continental mantle evolution since the Archean
Oxygen isotopic ratios are largely homogenous in the bulk of Earth’s mantle but are strongly fractionated near the Earth’s surface, thus these are robust indicators of recycling of surface materials to the mantle. Here we document a subtle but significant ~0.2‰ temporal decrease in δ(18)O in the sha...
