My research focuses on (1) the integrated application of thermochronology and geochronology to tectonic and geological problems to better understand the temporal and thermal aspects of tectonic, petrologic, stratigraphic, and geomorphologic processes. In particular, I am interested in combining structural geology with low-temperature thermochronology to elucidate the spatial and temporal distribution of deformation in intra-continental rifting, orogen-parallel extension, and continental rupture leading to seafloor spreading as well as collisional tectonics (e.g., coupling of fold-and-thrust sheet and foreland basin dynamics). (2) Geo- and Thermochronometry technique development, calibration, and bench marking, with special emphasis on development of new thermochronmeters (e.g., monazite, rutile, and magnetite) and novel applications (e.g., geoarcheology, isotopic provenance, etc.)

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.

 

Laser ablation (U-Th)/He and 4He/3He dating of zircon and apatite (Graduate)
Seeking motivated Ph.D. students interested in noble gas geo-thermochronology and geochemistry to pursue project in method development and application of laser ablation (U-Th)/He dating and depth profile 4He/3He thermochronometry of zircon and apatite. Our laboratory has a dedicated noble gas extraction line with a SFT magnetic sector noble gas mass spectrometer and dedicated Excimer Laser. The lab also houses two Element2 magnetic sector single collector ICP-MS instruments with a second Excimer laser as well as a state-of-the-art Bruker optical interferometric microscope. The project will develop laser ablation methodology to recover detailed thermal histories from apatite and zircon by laser ablation (U-Th)/He and 4He/3He dating as well as comparison to step-heating fractional loss experiments.

 

LA-ICP-MS single-pule U-Pb depth profiling recovery of thermal histories (Graduate)
Seeking motivated Ph.D. students interested in in-situ geochronology to pursue project in method development and application of laser ablation continuous mode or single-pulse U-Pb LA-ICP-MS geo-thermochronology as well as trace element speedometry to constrain thermal history or lower and middle crustal rocks. The UTChron Geo- and Thermochronometry laboratory houses two Element2 magnetic sector single collector ICP-MS instruments with a large-volume cell Excimer laser system, ideally suited for depth profiling and U-Pb and trace element split stream analysis. The laboratory also houses a Bruker optical interferometric microscope to control laser ablation rates as well as a Raman system. The focus of applications is on method development and application to the exhumation of middle and lower crustal rocks in rifted margin settings.

 

Detrital Geo- and Thermochronometry of Atlantic Rift Basins (Graduate)
Seeking motivated Ph.D. students interested in conducting integrated detrital zircon U-Pb and (U-Th)/He work on Triassic and Jurassic rift basins along the Atlantic margin in the NE USA and Canada and the conjugate margin of Morocco. The goal of the project is to understand basin sedimentation, sediment routing, and sediment provenance to shed light on lithospheric rift processes leading to Atlantic rifting and break-up. This project will combine stratigraphy, detrital geo-thermochronometry, and geodynamics to more holistically understand 2D and 3D sediment dispersal and lithospheric-scale controls on sediment dispersal and stratigraphic record during progressive rifting through time.

 

IMPACT: Geo- and thermochronometry of the Chicxulub Crater and KPg ejecta deposits (Graduate)
Seeking motivated Ph.D. student interested in investigating the thermal history of the recently drilled Chicxulub impact crater (IODP 364) in collaboration with Drs. Dan Stockli (DGS) and Sean Gulick (UTIG). The aim of the project is to test different hypotheses for the formation of the peak ring, to investigate the thermal evolution of the impact and the post-impact hydrothermal alteration as well as to explore KPg deposits in the USA and Cuba using U-Pb and (U-Th)/He geo-and thermochronometry. In addition, we envision to use other IODP and industry borehole samples as well as outcrop samples from the USA and potentially Cuba to elucidate the ejecta and tsunami deposits related to the KPg impact in the southern Gulf of Mexico to more holistically understand the impact and its effects on the circum-GOM region.
