Climate, Oceans and Biogeochemical Cycles

Climate, Oceans and Biogeochemical Cycles

  • Marine biogeochemical cycles of Pb, Nd, Hf, and Cd in the context of the international GEOTRACES program
  • Glacial-interglacial ocean circulation and ocean ventilation
  • Long-term ocean circulation patterns & climate change
  • Monsoon dynamics in Central Asia during the Holocene
  • Stability and dynamics of the Antarctic Ice Sheet
  • Global atmospheric dust cycle - Geochemistry and Modelling
  • Thallium isotope fractionations in the oceans - origin and applications
Magmatic Processes & Silicate Earth

Magmatic Processes & Silicate Earth

  • Constraints from Tl and Tl isotopes on global sub-seafloor hydrothermal fluxes
  • Insights on crustal evolution from sediment provenance - evidence from Ar-Ar, Rb-Sr, Sm-Nd, Lu-Hf and U-Pb isotope studies
  • Tl and Cd isotope studies of volcanic emissions
  • Tl, Zn and V isotope studies of oceanic basalts
  • Zn, Fe and Cu isotopes to study ore formation
  • Vanadium isotopes of oceanic and subduction-related basalts for constraints on mantle fO2
Cosmochemistry and Early Earth

Cosmochemistry and Early Earth

  • Investigation of planetary volatile depletion with non-traditional stable isotope systems
  • Combined 205Pb-205Tl & Cd-Zn isotope studies of chondrites and achondrites - the initial abundance of 205Pb, origin of volatile depletion and chronology of parent body metamorphism
  • The early Earth - chronology and mechanisms of accretion and differentiation
Environment & Health

Environment & Health

  • Bioinorganic chemistry of Zn and Fe isotopes in biological systems
