Faculty and students of the Tectonics and Sedimentation Research Group are conducting research that are both areally and topically diverse. Cathy Hanks, Andrea Strauch (M.S. student) and Alec Duncan (M.S. student) students continue to explore the relationship between fractures, stucture and stratigraphy in the rangefront of the Brooks Range. Al Kleck (M.S. student with Cathy Hanks) hopes to be able to extraplolate the observed surficial fracture patterns into the subsurface by mapping the in situ stress distribution in the Colville basin. Meanwhile, Wes Wallace is working with the ADGGS on the evolution of the rangefront of the central Brooks Range while his student, Rebecca Bailey (M.S. student) is developing geometric and kinematic models of thrust truncated detachment (?) folds.
On the sedimentary side of things, Paul McCarthy and his students Peter Flaig (Ph.D.) and Erik Brandlen (M.S.) continue to explore paleosols in the North Slope and Canada. Paul and Cheryl Hartbauer (M.S.) are also working with the ADGGS to develop a stratigraphic framework for potential hydrocarbon reservoirs on the Alaska Peninsula.

Dinosaurs in Denali!
This past summer, Paul McCarthy and UAF field camp undergraduate students Susi Tomisch and Jeremiah Drewel discovered dinosaur footprints in the Cretaceous Cantwell Formation in Denali National Park. The therapod footprint is the first evidence that dinosaurs roamed Interior Alaska. |
Mike Whalen will be on sabbatical during the 2006 Spring semester.
