Structural Geology/Lithospheric Geodynamics

Structural Geology and Tectonics draws on all geoscience disciplines to address fundamental questions about plate tectonic and deformation processes. In recent years, there has been an explosion of new technologies which allow scientists to answer questions that were once beyond their reach. This research not only leads to advances in basic research, but is also relevant to society, through the exploration for natural resources and understanding of natural hazards.


Structural Geology and Tectonics research at the Jackson School spans the entire spectrum from continental to oceanic and upper crustal to mantle tectonics. Only a handful of programs in the country cover such a wide range. Researchers investigate processes at all scales using field and marine geophysical-based observations; laboratory-based petrologic, geochronological, structural and geochemical analyses; and theoretical and physical modeling.

Tectonically-focused research addresses processes at active and ancient plate boundaries. At convergent margins, research topics range from subduction zone processes to continental collision, mountain uplift, and basin evolution. Extensional tectonic processes under investigation range from continental extension in the deep to shallow crust to evolution of passive margins, spreading ridges, and oceanic crust. Other research concentrates on the evolution of transitional plate boundaries as well as transform boundaries.

Other major research areas focus on deformation processes including thin-skinned fold and thrust belt processes and associated fluid flow; formation of salients; salt tectonics; and strain partitioning in extensional and contractional shear zones. Another major research focus is on understanding fracturing, fracture processes, fractured reservoirs, and relationships to diagenesis and fluid flow.

Innovative Detrital Provenance Studies - Double Dating PLUS

Graduate
A major thrust of my current research the development and application of more comprehensive isotopic detrital provenance tools. U-Pb on zircon is clearly the big work horse, but only goes so far and sometimes yields "no" useful info, e.g., if the source of the sediment is mostly recycled sediment. We have extensively pursued double dating of zircons by U-Pb and He, as zircon He ages yield very interesting insights into the thermal and tectonic history of the source terrane; often yielding very different insights than crystallization ages. The combination is powerful, but I think we can take things so much farther by combining double dating with other constrains. People have tried fission track (not precise enough), Hf/Hf (to get mantle separation model ages), etc., but what we want to do and are working on is really Double Dating ++, combining zircon U-Pb-He dating with a variety of other geochemical aspects to more comprehensive understand detrital provenance and improve paleo-tectonic reconstructions. For example, trace-element thermometry (Ti in zirc), REE on zircon (met vs mag origin), Hf/Hf (see above), oxygen isotopes, etc. and also to develop rutile in an analogous manner (e.g., Zr in rut thermometry, Cr/Nb ratio (mafic vs granulitic), REE, etc.). The sky is the limit and what can learn so much. The issue in part it, how much can a single grain tell us before it's gone? The project sounds very laboratory oriented, but it's really a combination of field and lab work. We have identified a few possible case study areas, e.g., Morocco; great exposures, long-lived and preserved record of basin deposition since the Precambrian. My group is already working on some case studies in NW Himalayas, the N & S Pyrenees, the Sevier FTB, Permian Basin and other foreland basin. New projects include provenance studies along rifted and passive continental margins such the Gulf of Mexico, the central Atlantic Margins in Canada, USA, Portugal, and Morocco.

We want to help inform Texas citizens so that they can keep their property safe from the impact of earthquakes.

Center for Frontiers of Subsurface Energy Security

CFSES is one of only two centers out of 46 EFRCs with focus on subsurface energy. Our goal is a scientific understanding of the physical, chemical, and biological subsurface processes from the very small scale to the very large scale so that we can predict the behavior of CO2 and other byproducts of the energy production that may need to be stored in the subsurface. At this aim, we need to integrate and expand our knowledge of subsurface phenomena across scientific disciplines using both experimental and modeling methodologies to better understand and quantify the behavior at conditions far from equilibrium. The unique aspect of our research is the approach of the uncertainty and of the complexity of the fluids in the geologic media from the molecular scale to the basin scale and their integration in computational tools to better predict the long term behavior of subsurface energy byproduct storage.
