Shear zone and fault kinematics and dynamics. Research focuses on the interaction between brittle earthquake faulting and slow plastic creep near the mid-crustal rheologic transition from brittle to ductile deformation. Recent work has also included processes of strain localization in debris-rick glacial ice. To understand these processes I employ a diverse range of research methods including detailed field mapping, optical petrography and orientation analysis, Electron Backscatter Diffraction (EBSD), metamorphic petrography, fluid inclusion microthermometry, and thermochronology.
Large-scale architecture and evolution of the continental lithosphere. Research is aimed at understanding the origin and evolution of persistent structures in the continental lithosphere and the influence that such structures have on later evolution of the continents. I have worked for years to understand structural trends that originated during Archean to Proterozoic assembly of the North American Lithosphere and have been repeatedly reactivated during subsequent tectonic episodes.
Fluid-rock interactions in fractured CO2 reservoirs. Experimental investigation of chemical reactions between supercritical CO2, brine and reservoir rocks during injection of CO2 for geological carbon capture and storage (CCS) or enhanced oil recovery (EOR). Research employs a unique flow-through rock core reactor and advanced imaging of fracture networks using optical petrography, magnetic resonance imaging (MR), Computed X-Ray Tomography (mCT), laser confocal fluorescence microscopy and other methods.
Structure and rheology of geologic materials. I use Electron Backscatter Diffraction, optical orientation imaging and other laboratory methods to investigate the crystalline structure of natural materials including rock, ice dinosaur eggshell and (potentially) bone.
Homestake Shear Zone, Colorado. The HSZ is a Proterozoic shear zone system in the Sawatch Range of central Colorado that formed approzimately 10-15 km beneath the surface. More than a billion years of erosion brought the tectonites of the shear zone allowing us to use these rocks to study processes of faulting that occur deep in the middle crust. The HSZ preserves a record of contemporaenous brittle and ductile deformation and encompasses one of the largest pseudotachylyte-bearing seismiogenic fault systems that has been described to date.
