I am interested in applying isotope geochemistry to terrigenous sediments as a means to studying past climate change, espeically ice sheet dynamics. My current research is focused on sedimentary provenance work around East Antarctica. To study this I am using 40Ar/39Ar dating of detrital hornblendes, biotites and feldspars and Nd isotope analysis of terrigenous (ice rafted) material in sediment cores around the perimeter of East Antarctica between the Ross Sea and Prydz Bay. Identifying the characteristics of the sediment being shed from the continent around the perimeter allows for characterizations not only of the geology of East Anatarctica, which is mostly obscured by thick ice, but also for identifying shifts in the provenance of ice rafted detritus in down-core records.
