• Quantitatively Tracking the Elevation of the Tibetan Plateau Since the Cretaceous: Insights From Whole‐Rock Sr/Y and La/Yb Ratios

  Geophysical Research Letters · 2020 · 108 citations

  Abstract Crustal thickness, elevation, and Sr/Y and (La/Yb) N of magmatic rocks are strongly correlated for subduction‐related and collision‐related mountain belts. We quantitatively constrain the paleo‐elevation of the Tibetan Plateau since the Cretaceous using empirically derived equations. The results are broadly consistent with previous estimates based on stable isotope and structural analyses, supporting a complex uplift history. Our data suggest that a protoplateau formed in central Tibet…

  Geology · 2022 · 32 citations

  1st authorCorresponding

  Abstract Subduction of lithospheric plates at convergent margins leads to transport of materials once close to or at the surface of Earth to great depths. Some of them later return to the surface by magmatism or degassing, whereas others end up being stored in the mantle for long periods of time. The fate of carbon-bearing minerals in subduction is of particular interest because they can arbitrate the long-term availability of CO2 at the surface. However, there are major gaps in the understandin…

• Latitude-dependent oxygen fugacity in arc magmas

  Nature Communications · 2024-07-18 · 15 citations

  articleOpen access

  Abstract The redox state of arc mantle has been considered to be more oxidized and diverse than that of the mid-ocean ridge, but the cause of the variation is debated. We examine the redox state of the Cenozoic global arc mantle by compiling measured/calculated f O 2 of olivine-hosted melt inclusions from arc magma and modeled f O 2 based on V/Sc and Cu/Zr ratios of arc basaltic rocks. The results indicate that the redox state of Cenozoic arc mantle is latitude dependent, with less oxidized arc…
