|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 NE Africa (Egypt), Sevier FTB and foreland basin, and the Colombian Llanos and Magdalena Basins.

|Exhumation of the Central Alps, Switzerland (Graduate)|
Being Swiss, I have had a long-standing interest in the Alps and over the past few yearsI have had two students working on the exhumation of the eastern Alps (Engadin) and the Molasse foreland basin. Over the past decade different models have explored the role of climate (incl. Messinian salinity crisis) vs tectonics (out-of-sequence thrusting etc.). The exhumation of the northern Alpine external massives (esp. central Aar Massif) in Switzerland is key in solving this problem. We have a detailed study in the western Aar Massif and it has really questioned a lot of the thinking in terms of the late-stage structural and tectonic reconstruction of the Alps and the evolution of the Alpine critical taper. This is also a project a lot of people would be very interested in in terms of the results. I have collected some samples, but a lot more work needs to be done in the field and the laboratory. Some of the sampling might require good fitness etc. or more. In addition to surface sampling, there are also a lot of tunnels and the potential of 3D modeling to really understand and solve this problem.

|Fault and fracture processes, structural diagenesis (Graduate)|
Graduate student projects combine the fields of fault and fracture mechanics and low-temperature geochemistry addressing deformation mechanisms of the upper crust, structural control of mass and heat transfer in sedimentary basins, the effects of chemical mass transfer on the mechanical and hydraulic behavior of fractures and faults, and the chemical interaction between fluids and minerals. Projects usually require the integration of field and laboratory analytical or numerical work and preference goes to applicants that are equally comfortable in the field and in the lab. Research topics include field- and core-based structural geology, geomechanics, geofluids, geochemistry, and natural resources including CO2 sequestration. A current research emphasis lies in Structural Diagenesis which combines the traditionally separate fields of brittle structural geology and diagenesis/geochemistry. Preference goes to PhD applicants with a prior MS degree and MS applicants with undergraduate research experience, preferentially through completion of a senior's thesis. Applications for Fall 2014 should be submitted to the MS or PhD program in Geological Sciences (GEO). Please contact Peter Eichhubl (email@example.com for further details.

|Academic Seismic Portal at UTIG|
The portal is the gateway to the Marine Seismic Data Center (MSDC). MSDC's goal is to support education and research with access to and preservation of academic active-source seismic data. Our partner, the Academic Seismic Portal at LDEO, has a complementary seismic inventory primarily of field data. These cooperating data centers, part of the Marine Geoscience Data System, are supported by the National Science Foundation.
The desktop cathodoluminescence system provides valuable visual information from rocks and minerals not seen using regular light petrography or other electron beam equipment. Here, electrons bombard a regular rock thin section and the sample glows in visible light. A high-resolution digital camera captures the images. Applications include examining carbonate textures, quartz overgrowths and filled fractures in sedimentary rocks and understanding mineral zoning and fluid interactions in intrusive igneous rocks.

|Ocean-Bottom Seismometer (OBS)|
An Ocean-Bottom Seismometer (OBS) is a seismometer that can be deployed on the seafloor for weeks or months, recording either earthquakes or man-made seismic signals. To withstand pressures at large depth (up to 5500 m) in the oceans, all electronics of this instrument are kept inside a glass sphere which can withstand such pressures. The sensors of all instruments (discussed below) include a 3-component accelerometer and a hydrophone, all designed for seismic data with a dominant frequency near 10 Hz. The seismic data are recorded on flash memory. Correct timing of the seismic recording is provided by an accurate clock, which also resides inside the sphere. After a seismic study on the seafloor is complete, the instrument is brought back to the sea surface using an acoustic release mechanism. UTIG has long been involved in marine seismology. The development of a UTIG OBS instrument program began in 1978.
There are several aspects to our laboratory that make it different from others. One is our automatic handler system created at California Institute of Technology and adapted for our needs. Scientists and students can keep up with changes to our system by keeping in touch with the other 6 similar systems in the world and RAPID Consortium at http://rapid.gps.caltech.edu/. It also includes a cryogenic magnetometer and portable magnetic susceptibility meter (TerraPlus KT-10 Plus).

The 24-channel system is designed to be transported worldwide and to be installed on vessels of opportunity. Survey design, navigation, data acquisition, and near real-time MCS processing can be performed on non-dedicated laptops in the field. Deployment and recovery of gear is done by hand, requiring as few as 3 persons. The only constraints on the system are weight limits of the vessel and electrical requirements of the dedicated air compressors. For platforms with insufficient electrical capabilities, a fuel-powered generator or air compressor can be rented as a substitute.
