    Mendenhall Research Fellowship - Research Opportunity # S45. Applying radiogenic isotope geochemistry to enhance geologic framework models

    The National Cooperative Geologic Mapping Program (NCGMP) of the USGS has the primary goal of producing detailed geologic framework models for the Nation. This mandate includes creation of appropriate geologic maps and other datasets needed to address national issues of land-use management, natural resources assessment/utilization/conservation, groundwater management, hazard assessment, and environmental protection using an unbiased, science-informed approach. Reliable geologic framework models require characterization of the map units involved as well as an understanding of their petrogenic origins and evolution through time. This requires collection and integration of data that better define the spatial and temporal distributions of sedimentary, igneous, and metamorphic lithologies and the processes that created the surface and subsurface geology of the Nation. Geochronology and isotope geochemistry provide invaluable information for geologic framework development by placing absolute ages on mappable rock and sediment units, tracing fluid flow paths, and identifying processes of tectonics, volcanism, paleoenvironmental change, and economically-important mineralization, among others.

    Proposed Duty Station:  Lakewood, Colorado

    Areas of Ph.D.: Isotope geology, geochemistry, petrology, mass spectrometry (candidates holding a Ph.D. in other disciplines but with knowledge and skills relevant to the Research Opportunity may be considered).

    Qualifications: Applicants must meet one of the following qualifications: Research Geologist, Research Chemist

    (This type of research is performed by those who have backgrounds for the occupations stated above. However, other titles may be applicable depending on the applicant's background, education, and research proposal. The final classification of the position will be made by the Human Resources Specialist.)

    Physical/Environmental Demands:

    Most of the work is in an office and laboratory, covered by the following:

    • Office settings will include normal everyday risks or discomforts associated with desk and computer work that requires normal safety precautions typical of offices or meeting rooms.
    • Laboratory work involves use of very low-level radioactive materials in a controlled-access, Class-10,000 clean room along with use of corrosive reagents (acids). The work also involves mass spectrometers operating at high voltages which present electrical shock hazards. The incumbent is expected to be able to work at chemistry benchtops and be able to lift and pour up to 5 liters of hazardous liquids. Risks and hazards in lab settings require safety precautions and training.

    Work will involve fieldwork, covered by the following:

    • Field work involves exposure to moderate risks and discomforts due to (1) adverse weather conditions including temperature extremes, wind, and precipitation events, (2) travel in safety-approved small aircraft and watercraft or off-road vehicles, (3) hostile wildlife including poisonous insects, reptiles, or plants (4) physical exertion in mountainous terranes or subterranean settings (caves or mines).

    Travel Required

    Occasional travel - Overnight travel of 1 to 5 nights per month may be required.
