PhD position at the Department of Geology/University of Erlangen (Germany) The project will investigate the oxygen isotopic composition of biogenic apatites mainly from the Paleozoic. The investigations are part of a larger research project dealing with the geochemical evolution of System Earth within the time period of the Devonian to Permian. The candidate will be involved in field work, separation of biogenic apatites, chemical and basically stable isotope analyses of biogenic apatites. Isotopic analyses will be performed with a infrared laser – GC-IRMS system. The position is financed by the German Science Foundation DFG, and funding is currently available for 20 months (starting 01.01.2000). The maximum funding period will be 36 month. Preference will be given to applicants familiar with laboratory work and experience in stable isotope geochemistry. Further applicants should be fluent in English or German. A master degree or equivalent degree in Earth Sciences is required. Applications should include a CV and the names, addresses as well as E-mail addresses of two referees.
