Current Research Interest |
|
|
| |
- Basin analysis in fold-thrust belts and continental plateaus.
- Tectonic applications of sedimentology, stratigraphy, and provenance analysis.
- Quantitative modeling of modern and ancient sedimentary basins.
- Physical sedimentology of nonmarine depositional systems.
My research focuses on the erosional history of mountain belts as preserved in sedimentary basin fill. The principal goal is to understand the timing and spatial history of deformation and associated basin development.
Current research includes projects in Asia, the Middle East, South America, and North America. Studies in Asia are aimed at quantifying the timing of surface uplift and amount of contractional and strike-slip deformation associated with Mesozoic-Cenozoic basin development in the Tibetan plateau prior to and during the India-Asia collision. In the Middle East, research on the Zagros mountains will help determine the sedimentary and structural record of recent continent-continent collision. In South America, separate projects on Cretaceous-Tertiary foreland basin system exposed in the Bolivian thrust belt, mid-Tertiary strata in the Altiplano hinterland plateau, and late Tertiary extensional-basin fill in the Cordillera Blanca of Peru help define the kinematic history of shortening and extension in the Andes. In the North American Cordillera, analyses of the Cretaceous-early Tertiary foreland basin in north-central Utah involve reconstruction of the tectonic development of the Charleston-Nebo salient and associated deposition of stratigraphic sequences in the Book Cliffs region. These varied projects involve field work, quantitative basin modeling, sandstone petrographic analysis, structural mapping, Ar/Ar and (U-Th)/He thermochronology, magnetostratigraphy, and stable isotope geochemistry.
