New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycl ....New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycle, blurring source-sink relationships, b) zircon may be absent in mafic lithologies thus biasing investigations. In this work K-feldspar & apatite provenance investigation will be undertaken on a state wide basis and include case studies in the Yilgarn Craton and Canning & Northern Carnarvon Basins.

Summary
High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality c ....High-resolution ITRAX XRF core scanning facility for global change research. This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less
