This position may be of interest to post-doctoral level researchers or more senior researchers as an exchange or sabbatical position. Such researchers would be appointed as "visiting scholars" and would work with one of our nearby universities as well as in our laboratory.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>The successful candidate would join scientists in the Noble Gas Lab to develop and refine the capability for Ar-Ar geochronology on our multicollector instruments. The candidate would work with the PI and other lab scientists to use the Ar-Ar system to address questions about solar system materials, for example, the origin of meteorites, the age of aqueous alteration, or other research of mutual interest. The MNGRL facility comprises two multicollector magnetic sector mass spectrometers (Nu Noblesse and Thermo Helix) with various modes of gas extraction (laser and furnace), two <i>in situ</i> geochronology development projects, and sample examination and preparation capabilities.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>Applicants should hold a Ph.D. in geosciences or a related field and have experience in noble gas analysis of geologic samples, either terrestrial or extraterrestrial.
