I grew in the sub-Alpine Molasse next to the external Helvetic Thrust sheets outside of Lucerne, Switzerland. I attended ETH Zurich as an undergraduate and worked in the Eastern Alps on orogen-parallel extension (Brenner Fault) for my M.S, before moving the USA in 1995 for my Ph.D. at Stanford University investigating the timing of Basin and Range extension. After a 2-year postdoc at Caltech during the early years of (U-Th)/He dating, I taught at the University of Kansas for a decade as an Assistant and Associate Professor and move to the University of Texas in 2011 as a Full Professor. I am currently the Chevron (Gulf) Centennial Professor in Geology, the Director of the UTChron laboratory, and the incoming DGS Dept. Chair (2021). During my time at KU and UT, I established cutting-edge (U-Th)/He, 4He/3He, and LA-ICP-MS laboratories (UTChron).

My research focuses on 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 ge0- and thermochronology to elucidate the spatial and temporal distribution of deformation in intra-continental rifting, orogen-parallel extension, and continental break-up leading (Basin and Range, Red Sea, Alps-Pyrenees, and the Aegean,) as well as collisional tectonics, timing of thrusting, and coupling of fold-and-thrust sheet and foreland basin dynamics (e.g., Sevier, Zagros, Verkhoyansk FTBs).

In addition to the application of geo- and thermochronometry to tectonics, my research group also focuses on both the developement and calibration, and bench marking of novel geochronology, thermochronology, and petrological tools. This includes a special emphasis on development of new He noble thermochronmeters (e.g., monazite, rutile, spinel, magnetite, spinel etc.) and LA-ICP-MS U-Pb and REE methods (e.g., U-Pb depth profiling, U-Pb-He double dating, U-Pb and REE split-stream analysis and 2D mapping, garnet U-Pb dating, etc.).

With the acquisition of a SFT Helix sector-noble gas machine coupled to an extraction line with diode laser and light-bulb furnace for fractional-loss step heating experiments and a dedicated Excimer Analyte G2 Laser for He laser ablation, our research foci also include thermal history recovery from single apatite and zircon grains and cosmogenic 3He dating.

Innovative Detrital Provenance Studies - Double Dating PLUS
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
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
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.

 

Ph.D. Project Greece - Petrochronology and tectonic evolution of the Cycladic Blueschist Complex (University of Texas at Austin) (4-5 years)
Ph.D. project available in the Stockli Research Group and UTChron Laboratory of the Dept of Earth and Planetary Sciences (https://eps.jsg.utexas.edu/) at the Jackson School of Geosciences (https://www.jsg.utexas.edu/) of The University of Texas at Austin. The project focuses on the tectonic and metamorphic evolution of the Cycladic Blueschist Complex in central and northern Greece to constrain the tectonic and metamorphic evolution of one of the world's best-exposed subduction complexes. The project entails field mapping and structural analysis with strong emphasis on accessory mineral (zircon, apatite, titanite) LA-ICP-MS petrochronology, microanalytical mineral imaging and elemental and isotopic mapping, and low-temperature (U-Th)/He thermochronometry of the Cycladic Blueschist Complex in central and north-eastern Greece with the goal of constraining the pre-subduction, subduction, and exhumation history of Cycladic blueschists and understanding subduction underplating within the Hellenic subduction complex. The project is a collaboration with the University of Athens (Prof. Soukis) and we are seek an outstanding, motivated, and independent PhD student with interested in combining field and cutting-edge laboratory work.

Interested candidates should contact Dr. Daniel Stockli with any inquiries and questions regarding the project or application procedures.
