Project Progress

Our group has been involved in several new projects this past year: (1) Geochronological studies of Archean rocks of southern West Greenland (with Harrison and Manning) and southern India (with Newton and Devaraju); (2) Nitrogen isotope and spectroscopic studies of Archean metasedimentary minerals (with Papineau and Marty); (3) Mass-independent sulfur isotope anomalies in Archean and Proterozoic sediments (with Karhu, Papineau, Coath, Greenwood, McKeegan and Harrison); (4) geochemistry of the oldest known zircons and the nature of the Hadean (pre-4 Ga) crust (with Harrison, Humayun, McKeegan, Sharma and Trail); (5) A mission to Really Early Earth drilling project (Harrison). We have manuscripts recently published, in press or submitted for the above projects. Laboratory development is also on going as we create an Astrobiology Materials Research Center at University of Colorado.
