Current Research Projects

Opportunities are available for motivated graduate students (M.S. and Ph.D.) to be involved in research projects in tectonics, economic geology, geochronology, and structural geology. Please e-mail me for more information.


Application of U-Pb geochronology to the solution of tectonic problems is the cornerstone of my research program.  These analytical studies are equally balanced with the fieldwork that provides their context. There are presently several dating methods required to cover the spectrum of tectonic problems being addressed. Conventional U-Pb analyses (ID-TIMS), whereby single crystals or groups of zircon grains are dissolved and analyzed, provide high precision ages for zircons with demonstrably simple systematics. Collaborations are available for completing CA-TIMS high resolution geochronology. Many dating projects require in situ analysis of parts of zircon grains by ion probe (SIMS) or Sensitive High Resolution Ion Microprobe (SHRIMP) techniques. These analyses are completed at the USGS/Stanford SHRIMP facility. Finally, the laser ablation ICPMS method for routine analysis of detrital grains and magmatic ages have utilized the facility at Washington State University and the University of Arizona LaserChron facility.  All of my currently funded projects utilize a range of SIMS and LA-ICPMS U-Pb geochronology.
