  • Using U-series isotopes to look at volatile movement within the magma system (i.e., 210Pb).
  • Using techniques such as SHRIMP SI and FTIR to determine the water content of pyroxenes from mantle and volcanic rocks. This data is used to estimate the volatile budget of the mantle through determining volatile inputs at subduction zones through to volatile loss by volcanism.
  • Constraining factors that fractionate U-series isotopes within the erosional environment of the Earth’s crust.
