Dear colleagues
I would like to draw your attention to an open PhD position available at the Bayerisches Geoinstitut
in Germany.
We are looking to fill a PhD position in experimental petrology and geochemistry within the
research program "Fractionation of sulfur, copper and gold in two-phase fluids", funded by the
German Science Foundation.
The applicant must have a masters or diploma degree in one of the fields of petrology/
mineralogy/geochemistry/economic geology.
The position is initially for two years, with the possibility for extension to three years. Salary is
according to the German civil service remuneration system E13/2 (i.e., 50% of E13).
The aim of this project is to experimentally investigate a phenomenon observed on natural fluid
inclusions from various ore deposits. Analyses of coexisting vapor and brine inclusions have
shown that copper and gold occur at higher concentrations in the vapor, in marked contrast to
most other ore-forming metals which fractionated into the coexisting brine. The fact that copper
and gold can be efficiently transported by the vapor phase has important implications for the
formation of porphyry Cu-Mo-Au deposits and epithermal gold deposits. In this study we will trap
aliquots of vapor and brine at elevated pressure and temperature in form of synthetic fluid
inclusions in quartz, and subsequently analyze them by Laser-ablation ICP-MS and other
microanalytical techniques.
Applicants should have a solid education in petrology and geochemistry, and demonstrate their
ability to perform laboratory-based research. Basic knowledge in thermodynamics and economic
geology is desirable.
Enquiries and applications should be sent to Dr. Andreas Audétat (andreas.audetat@uni-
bayreuth.de), including a CV and a full list of classes taken (with grades). Information about the
Bayerisches Geoinstitut can be found at http://www.bgi.uni-bayreuth.de/. Evaluation starts
immediately and will continue until the position is filled.
If you know any qualified person that might be interested in this position I would appreciate if you
could forward this message to him/her.
With kind regards,
Andreas Audetat
