Geochemistry/Thermo- & Geo-chronology

Researchers in this area use geochemical tracers to reconstruct the thermal history of rocks; characterize ancient environments and climates; reveal the interactions between climate, soils, and carbon dioxide (CO2) levels; and decipher fluid-rock interactions and mestasomatism at high temperature, relationships between metamorphic processes and deformation, and volatile transport in subduction zones to aid in quantifying geochemical cycles.


Our major research areas & groups in geochemistry include:

  • Major & Trace Element Geochemistry
  • Stable Isotope Geochemistry

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.
