Project title: The light element in Earth's core: constraints from S isotopes
Project description: Every continent has a package of extremely old Archean (>2.5 billion years) rocks at its core. These 'cratons' contain a record of Earth's earliest surface environments, and understanding their growth and destruction is a necessary condition for unraveling the early history of life on Earth. Lead isotopes monitor of the gross evolution of Archean cratons through their sensitivity to large-scale melting events and their general durability in the face of weathering under an anoxic Archean atmosphere. In the Superior geological Province of Canada, for example, a pair of late Archean 'blooms' of continental material has been inferred from lead isotopes in galena that occurs in sub-seafloor volcanic massive sulfide ore deposits. The same integrative nature that allows galena to concentrate lead isotopic information about Archean crustal growth enables it to sample the bulk sulfur isotopic character of Archean crust and upper mantle. This is a particularly useful tool in the Archean Eon, when the presence of S isotope anomalies enables one to ‘fingerprint’ S that has cycled through Earth’s atmosphere and exclude it from the dataset.

The objectives of this project are to determine the mean sulfur isotopic composition of the Archean crust and upper mantle. By comparing the bulk sulfur isotopic composition of Archean crust and upper mantle to the sulfur isotopic record in meteoritical sulfides, we will be able to determine whether Earth contains a 'missing' sulfur reservoir (e.g., in the core). If an such an imbalance is found, the S isotopic fractionation factor between ‘core’ and ‘silicate mantle’ in planetary environments will be determined from Pallasite meteorites. Such a fractionation factor will enable quantitative evaluation of the percentage of S that makes up the light element in Earth’s core.
