The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association, we are part of the largest German scientific organization. With around 1,300 employees (including our guests) we develop a sound understanding of the systems and processes of the solid Earth as well as strategies and options for action to face global change and its regional impacts, to understand natural hazards and reduce associated risks, and to assess the influence of humans on the Earth's system.

As a partner in Geo.X, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities.

For section 3.1 "Inorganic and Isotope Geochemistry" (department 3 "Geochemistry") we are looking for a:

PhD Student (m/f/x) – Boron Isotopes Job Vacancy No. 4329

on the topic "Experimental boron isotope fractionation between silicate melts and aqueous fluids with application to magmatic-hydrothermal ore genesis".

This is a team project of the GFZ with the universities of Potsdam and Köln. It will address a critical aspect of ore deposits related to granites and pegmatites: the magmatic-hydrothermal transition. The candidate will use a range of modern experimental and analytical techniques in stable isotope geochemistry and apply the results to real-world problems of ore genesis. The DOME priority program
(Dynamics of Ore Enrichment) is a multidisciplinary research platform with special training offers for young scientists.

Your responsibilities:

  • prepare sets of boron-doped, hydrated silicate glass as granite analogues
  • collaborate with team members determining B-speciation and B-diffusion
  • conduct high-temperature exchange experiments between glasses and aqueous fluid
  • characterize solid and fluid experimental products with SIMS and TIMS techniques
  • evaluate results to derive B-isotope fractionation factors and apply these to real-world data sets from ore deposit
  • participate in English in internal meetings and workshops of the DOME program
  • present in English the project results in professional meetings
  • prepare peer-reviewed publications in collaboration with the project team
  • complete requirements for a doctoral degree at the University of Potsdam

Your qualifications:

  • M.Sc. degree (or equivalent) at the time of appointment in geoscience or physical chemistry
  • good knowledge of mineralogy and geology; economic geology would be an advantage
  • experience or strong interest in laboratory-based research
  • strong command of written and spoken English; German language skills would be an advantage
  • enthusiasm and scientific curiosity, ability to work independently and in a team
Starting date: 1st October 2020
