Jackson School of Geosciences, University of Texas at Austin

The Department of Geological Sciences in the Jackson School of Geosciences at the University of Texas at Austin offers a position for a postdoctoral fellow to conduct research in the areas of groundwater geochemical evolution and paleoclimate reconstructions. These studies are focused on the limestone aquifer and caves in Guam in the tropical western Pacific, in collaboration with the Water and Environmental Research Institute of the Western Pacific at the University of Guam. The research involves groundwater and rainwater geochemistry, including stable and radiogenic isotopes, and paleoclimate, including reconstructions using speleothems and assessments of speleothem proxies in the modern hydrologic system. The postdoctoral fellow will lead the analyses and interpretations of the geochemical time series and manage the project database.

Requirements include a Ph.D. in relevant discipline(s) and one or more of the following areas of expertise: 1) stable and radiogenic isotope geochemistry of groundwater; 2) hydrogeology of karst systems; 3) petrography and geochemistry of speleothem calcite; 4) U-series isotopes analytical methods; and 5) tropical Pacific climate and time-series analysis. The Department and Jackson School have excellent analytical facilities in isotope geochemistry and a wide range of karst and climate science research expertise.

Pending arrival of funding, the position will be available starting in spring 2014 and may be renewed for up to a total appointment of four years. Typical starting salary for a Postdoctoral Fellow in the Department is $50K/annually plus benefits.

The New Mexico Institute of Mining and Technology (NMT) invites applications for two tenure-track assistant professor level positions in Hydrology and one in Geochemistry. For the hydrology positions, we seek candidates with interests in flow and transport in porous media, hyporheic zone studies, karst hydrology, hydrogeomechanics, isotope hydrology, or aqueous geochemistry. For exceptionally well-qualified hydrology candidates an appointment at the Associate Professor level will be considered. For the geochemistry position, we seek candidates with interests in igneous petrochemistry (especially volcanic rocks), metamorphic petrology, sedimentary geochemistry, geochemistry of ore deposits, and radiogenic isotope geochemistry. Potential for excellence in teaching and research are the most important qualifications.
Applicants should submit a letter of interest, resume, a statement of teaching and research interests, one representative publication, and the names of three references to Hydrology Search, Human Resources, New Mexico Institute of Mining and Technology, 801 Leroy Pl., Socorro, New Mexico 87801. College transcripts will be required if selected to interview. Review of application material will begin on October 1, 2014. The search will remain open until the position is filled. Email applications are not accepted. New Mexico Tech is an equal opportunity/affirmative action employer.
Applicants should have a Ph.D. in Earth Science, Civil or Environmental Engineering, or a related field at the time of appointment. Women and underrepresented minorities are encouraged to apply.

3D Modelling (geometry and connections) of carbonate massifs in structurally complex areas : An application to buried karst reservoirs of Languedoc (South France)

More details here. 

Karstic reservoirs offer new opportunities to secure water resources in the populated and arid regions, such as the Mediterranean. Karstified Jurassic carbonate massifs presently buried beneath Cenozoic cover have been studied in the south of France by BRGM, and more recently by Husson (2013)

Objective

The objective is to develop a method to determine the 1) distribution, 2) connectivity and 3) intensity of karstification of the carbonate massifs, including buried karsts. The study area (Languedoc) incorporates the previous (Husson, 2013) study and extends south-westward, i.e. downstream of the watershed. This study area is well suited for developing and validating the method (good data coverage & known geodynamic evolution), which can then be exported, especially in Mediterranean region.

Operations

1- Construction of a 3D geological model of this poly-deformed area; the model will include all geological information concerned with the (paleo)karsts and (paleo) base-level indicators. Surface geology, 2D seismic reflexion, exploration borehole data, gravimetry will be compiled and integrated, within the BRGM-Intrepid “Geomodeller”. While building the geomodel, tests of consistency of 2D restoration of random lines (using Schlumberger-Igeoss “Dynel2D”) will provide a validation of the geomodel. Additionnal validation will be secured by gravity inversion of the geomodel and comparison with available measured gravity data.

2- Sequential 3D restoration of the geomodel, at successive times of documented karstification (Messinian, Late Miocene, Early Paleocene, Mid-Cretaceous), using Schlumberger-Igeoss “Dynel3D”. Restoration will provide for each period : the flow-lines within the massifs from upstream topography towards the outlet, whether it is surficial (over impervious formations) or karstic (through carbonate massif) drainage. Karstified and non-karstified (above and below base-level, respectively) carbonate massifs will be delineated within the restored geomodels, for each karstification periods.

3- These paleo-base levels, obtained at the different stages of karstification will be input in the present day geomodel, in order to determine the distribution of karstified portions of the carbonate massifs (located above paleo base-level). The output will be the volume of potentially karstified massifs and the distribution of superimposed karsts, the later being an indication of increased karstification.

4- Gravity inversion of the 3D geomodel (with BRGM-Intrepid “Geomodeller”) provides density distribution. We suggests that lower density values within the carbonate formations, correlate with karstified areas. The gravity inversion results will be analysed (qualitatively & quantitatively) and correlated with the distribution of karstified massifs derived from the previous stage.

5- The findings will be analysed and tested in the light of regional hydrogeological data.

Applications:

- Exploration of karst reservoirs (water, oil & gas, mining industry)
- Management of karst reservoirs (water supply, hydrothermal resorts, gas storage, geothermy)
