Geophysics and Tectonics

Global earth science problems are as diverse as the techniques we use to tackle them.  Geophysics and Tectonic studies combine field-based data acquisition and simplification of earth processes through understanding physical principles, and comprehensive mathematical and experimental methods.


Active Research Programs

  • Tectonism of Archean greenstone belts
  • Effects of large meteorite impacts
  • Temporal and kinematic evolution of orogenic belts
  • Tectonometamorphism of high grade metamorphic terranes
Climate Change and Quantitative Geomorphology
  • Global climate patterns: Multichannel seismic images of Antarctica
  • Sediment and climate interaction --Gulf Coast Offshore Sequence Stratigraphy from single-channel seismic images
  • Quaternary paleoclimate studies from geophysical characterization of sedimentary sequences
  • Quantitative geomorphological modeling of uplift/erosion in a variety of geological settings
