Current Research Interests

1) Tracing fluids through fault zones with carbonate clumped isotope paleothermometry.

With the development of a new clumped isotope facility here in ESS (by Kate Huntington), we have the opportunity to exploit this new tool for the study of fluid migration and heat advection in the upper crust. Initial work by MS student Sara Bergman illustrates how clumped isotopes capture the spatial distribution of fluids with different origins around fault zones. I a new funded project through the Petroleum Research Fund to expand the initial proof of concept to encompass a broader perspective of the fault zone.

2) New tools for measuring 3D deformation: structure-from-motion photogrammetry for structural geology

What if we could generate a high-resolution digital surface model for any outcrop? Structure-from-motion (SfM) photogrammetry holds the potential to offer "LiDAR in your pocket", using simple digital photos and sophisticated image processing to produce DEMs. I am experimenting with this tool to produce quantitative measures of structural features, beginning with a collaborative project in review at NSF. With graduate student Keith Hodson, we will build a 3D model and quantitative description of an excavated fold in Pennsylvania, to test predictions that relate fold curvature (tightness) to secondary faults and fractures around the fold.

3) Viscous remanent magnetism as a geochronologic tool.

A rock acquires its primary magnetization at the time of formation. If the rock is subsequently disturbed by a geomorphic event such that it becomes misaligned to the magnetic field, it may begin to acquire a viscous remanent magnetic (VRM) overprint. Rock magnetics theory predicts a relationship between the time a magnetite-bearing rock has spent in a magnetic field and the temperature of demagnetization of the overprint. The longer a single-domain magnetite grain remains misaligned to the magnetic field, the higher the temperature required to remove its VRM overprint. In principle, this relationship can be exploited to determine the age of a geomorphic disturbance, such as landsliding, transport by glaciers, or fault-scarp degradation. From the theory, we expect to distinguish among historical (<1ka), Holocene (~10ka), late Pleistocene (~100ka), and earlier Quaternary events. An initial test (presented at GSA 2010) met this expectation, distinguishing between a 500 yr old rock fall and a 14ka outburst flood event. MS student Danika Globokar is completing a study to test this technique in granodiorites and for older geomorphic events.

4) Pacific Northwest neotectonics.

Cascadia is a "world class" laboratory for investigating orogenesis, subduction zone processes and arc volcanism at a variety of timescales. There is also a compelling case for local research that illuminates seismic and volcanic hazard. New techniques and observation of the last decade (high-resolution topography from LiDAR, densification of the geodetic and seismic networks, low temperature thermochronology) have driven a rapid evolution of understanding in Neogene-to-recent tectonism in the region. My recent work on Mount Baker volcano (c.f. recent publications) and on-going analysis of thermochronologic data from the North Cascades address questions at opposite ends of the time line. I have initiated a new project to revisit the structural geometries of the Yakima Fold and Thrust Belt: new LiDAR and aeromagnetic data, combined with careful geologic mapping will test competing models of the depth of faulting there. This has application to on-going seismic hazard assessment for critical facilities on the Columbia Plateau. Student Brendan Miller is a collaborator in this work, supported by USGS NEHRP funding.

5) The kinematics and mechanics of kink bands in foliated rock.

Kink bands are small folds with straight limbs and angular hinges (like a "z"). These structures have the characteristics of ductile deformation (folding) but behave in laboratory experiments and geometric relationships similar to brittle fractures. The kinematics of these structures have been long-debated and the mechanics are not well described. Exploiting an unusually-well exposed array of kink bands in a re-claimed quarry on Samish Island (WA), collaborators and I have applied classical structural geology techniques (field mapping, thin sections) and new approaches (magnetic fabrics, laser-scanning microtopography, analytical geometry) to describe and understand these enigmatic features. Former student Rachael Dunham and I have two recent papers on this work.
