Sediment provenance, paleoclimate

 

My research applies geochronology and radiogenic isotopes in minerals and bulk sediments to constrain the subglacial geology of Antarctica and to apply this geological information to tagging paleo-iceberg discharges from the Antarctic Ice Sheet.  My primary approach is to use the 40Ar/39Ar age of detrital hornblende grains.  Hornblende is a relatively abundant, rock-forming mineral that records the last major tectono-thermal event in a region.  It has been previously demonstrated that hornblende ages provide a robust division of Antarctica that conforms to the natural glacial divides around the continent.  My work is a combination of more precise documentation of the geological history, and the application of the approach to the paleo-climate related changes in the Antarctic Ice sheet.
