Rick is field geologist who dreams of winning a hill stage in the Tour de France. When not riding or sleeping, Rick enjoys investigating the structural stratigraphic and tectonic controls on generation of world-class Au deposits. To compliment the results from detailed field mapping, he uses a variety of geochemical and geochronological techniques to assess the timing and tectonic importance of major shifts in provenance of volcano-sedimentary successions. Of particular interest, is the application of U–Pb age dating of detrital zircons using the laser ablation ICP-MS, which represents a rapid (up to 10x faster) and considerably cheaper alternative to U–Pb age dating than using the SHRIMP. Recently, these pursuits have led Rick to consider broader issues in Earth’s history, such as possible tectonic triggers for the sudden appearance and explosive radiation of animals on Earth (i.e., the ‘Cambrian explosion’). Rick is currently working on the architecture and evolution the Archean 'late basins' in Western Australia that host numerous very big Au deposits. The principal aim of this research is to assist exploration geologists to find several more world-class and highly profitable Au deposits. Vive le Tour.
