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.

Using Big Climate Data to Plan for Water Stress in the Western U.S.

Undergraduate - 10 hrs/wk through Fall 2020, eligible for renewal for up to two years
Many communities and industries across the United States, particularly in the Western U.S., already struggle to meet their water needs. State-of-the-art climate projections suggest that climate change will only intensify these problems, but water decision-makers often struggle to apply the available climate projection data to their management needs. The student working on this project will use high-resolution climate model projections of future water cycle conditions in the Western U.S. to analyze how the metrics that matter most for regional water management may change in the future. Opportunities available to present within the University community and in external venues and to engage with decision-makers. Helpful skills: Basic experience navigating a Linux-based system using the command line Familiarity with opening and plotting gridded data files in a programming language like Matlab or Python Eagerness to self-teach any new programming skills necessary Thoroughness with documenting code and research activities.

Major instrumentation includes: (1) Gas chromatograph-single quadrupole mass spectrometer (GC-IRMS) for quantification and identification of organic compounds, and (2) HPLC-signgle quadrupole mass spectrometer (HPLC-MS) equipped with intelligent fraction collection for identification, quantification and isolation of high molecular weight compounds.

Paleolimnology Laboratory

Revolving Environmental Lab

The REL includes a geoprobe for drilling, an Ion Chromatograph for analyzing anions and cations, and a stratified aquifer sampler for analyzing varying groundwater flow and quality with depth.

Stable Isotope Lab for Critical Zone Gases

This lab is designed for the study of caves, soils and vegetative canopies. The GasBench II and Thermo Electron 253 in the High Temp. Stable Isotope lab are currently being used to measure the carbon isotope composition of soil and cave CO2, CO2 respired in soil respiration experiments, and dissolved inorganic carbon and calcium carbonates from multiple environments.
Superconducting Gravimeter Lab

Superconducting Gravimeter Lab

A GWR superconducting gravimeter (precision ~0.01 micrGals) configured to be transportable, used in hydrologic and other studies. This is usually deployed in the field for campaigns of months and longer.
UT Experimental Deep Water Basin

UT Experimental Deep Water Basin

The UTDW Basin is an experimental tank designed to physically model morphodynamic and stratigraphic evolution of continental margins and other subaqueous sediment transport systems. It is 4 m wide, 8 m long, and 2 m deep. The tank has 5 observation windows, underwater lighting and an array of synced overhead cameras. The facility is designed to map underwater deposit surfaces in space through time and measure fluid dynamic and sediment transport properties of formative density flows.
UT Sediment Transport and Earth-surface Processes (STEP) Basin

UT Sediment Transport and Earth-surface Processes (STEP) Basin

The STEP Basin is an experimental flume designed to physically model morphodynamic and stratigraphic evolution of the fluviodeltaic system. It is 4 m wide, 5 m long, and 1.5 m tall. This facility is one of only three in the world with a computer-controlled basement motion, which can mimic 1) fore-hinge (passive margin), 2) back-hinge (foreland basin), and 3) lateral tilting subsidence patterns.
Walter Geology Library

Walter Geology Library

The primary research collections of the library presently include more than 100,000 book and journal volumes and 46,000 geologic maps, among them the publications of the U.S. Geological Survey, most state geological surveys, and those of many foreign countries. Regional emphasis of the collection is on the Southwestern United States, Texas, and Mexico. The Institute and Bureau also have extensive libraries related to their specific research areas.

Wind Tunnel/Flume Lab

The Department of Geological Sciences maintains two wind tunnels for experiments in aeolian transport. One tunnel (0.5 m2 X 10 m) features a long transport section that ends in a slipface. The second tunnel features a rotating table (1 m in diameter) that can be used to simulate any range of wind directions.

Center for Integrated Earth System Science

The Center for Integrated Earth System Science (CIESS) is a cooperative effort between the Jackson School of Geosciences and the Cockrell School of Engineering. The center fosters collaborative study of Earth as a coupled system with focus on land, atmosphere, water, environment, and society.

Land, Environment & Atmospheric Dynamics

The LEAD group consists of graduate research assistants, postdoctoral fellows, research scientists and visiting scholars. We view the earth system in a holistic way, linking the atmosphere, ocean, biosphere, cryosphere, and solid earth as an integrated system. We use powerful methodologies such as satellite remote sensing and supercomputing simulations which are now profoundly changing research in earth system sciences. We place a strong emphasis on the societal impact of the research in earth system sciences.

Center for Space Research

The University of Texas at Austin, Center for Space Research was established in 1981 under the direction of Dr. Byron D. Tapley. The mission of the Center is to conduct research in orbit determination, space geodesy, the Earth and its environment, exploration of the solar system, as well as expanding the scientific applications of space systems data.
