Bruce Wilkinson

Research Professor of Earth Sciences

Research and Teaching Interests


My research interests are now a bit broad, and include sedimentary geology, broad-scale manifestations of global rock cycling, the crustal inventory of precious metals, and the importance of humans as geomorphic agents.

Current Projects:

*Discrimination of “metallogenic epochs” with Steve Kesler at the University of Michigan. Which intervals of geologic time, if any, have witnessed greater and/or lesser rates of epithermal gold mineralization?

*Determination of rates of rock cycling from age frequency distributions of lithotope areas on global geologic maps with Brandon McElroy at the University of Texas, Steve Kesler at the University of Michigan, and Shanan Peters at the University of Wisconsin. Everyone knows there is more exposure of young rock and less of old rock. Can this constrain rates of rock cycling?
Rock Recycling

* Tectonic uplift and erosion of orogenic belts have long been the most important processes that shape continental surfaces, but the rate of geomorphic change resulting from these natural phenomena has now been outstripped by human activities associated with agriculture, construction, and mining. What exactly are long-term and short-term rates of sediment transfer in response to glacio-fluvial and anthropogenic processes?

Students


Students - Because I am a retired Research Professor, I no longer directly supervise graduate students. However, I do serve on the committees of several of the graduate students, and manage to provide (solicited and unsolicited) advice to most of the others.
