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


Tectonics
  • 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

Sediments, Fluids and Faults
  • Fault networks in aquifers from 3D seismic images and ground penetrating radar
  • Overpressuring in sediments from 3D seismic attributes
  • Tectonic evolution of rift basins
  • Gravity, flexure, and rheology of the lithosphere
  • Heat flow and evolution of sedimentary basins
  • Fluid-flow models in fault zones: X-Ray tomographic characterization of fault zones
  • Global and regional correlation using magnetic susceptibility and biostratigraphic data sets
