Structure, Tectonics, and Geodynamics

Structural Geology

  • Structural evolution of the Black Hills Precambrian
  • Investigation of structural controls on gold mineralization (Nevada and Black Hills region of South Dakota)
  • Regional structure of the Niobrara Formation South Dakota, Wyoming, and Nebraska
  • Structural geology of the Slim Butte area, Pine Ridge Indian Reservation, South Dakota
  • Structural evolution of metamorphic core complexes and detachment faults (Western Turkey and Basin and Range - USA)

Tectonics

  • Laramide tectonics
  • Geotectonic evolution of supradetachment basins (Western Turkey and Basin and Range - USA)
  • Kinematics of extensional and extension-parallel faulting
  • Computational thermodynamic/phase equilibria modeling research in convergent plate margins
  • Role of volatiles (Cl, F, S, H2O) in silicate melts during crustal formation and differentiation (fractionation, degassing, high-T metamorphism, and fluid/rock interaction)

Geodynamics

Geodynamics (Geo: Earth and Dyamics: Forces) uses numerical models to quantitatively link our geophysical observations to the inaccessible processes at depth. The Geophysics Research Team conducts geodynamics investigations that significantly impact global natural hazards assessments and bring international attention to the South Dakota School of Mines. These investigations use Finite Element Models (FEMs) for:

  • Megathrust (M9) quakes and Tsunami Genesis
  • Poroelastic deformation, viscoelastic creep, and triggered aftershocks
  • Reservoir impoundment and induced seismicity
  • Magma flux of active volcanoes
  • Inverse models of InSAR and GPS data 
  • Optimization and uncertainty
