The Institute of Mineralogy at the Leibniz Universitšt Hannover (Germany) invites applications for a 3-year PhD position in igneous petrology starting in Spring 2017. In the frame of a DFG-funded Emmy Noether project to Olivier Namur, we seek a highly motivated doctoral student who is interested in pursuing fundamental research in earth sciences. The candidate should have basic knowledge in the areas of igneous petrology and thermodynamics. Required qualifications are an interest in experimental work and a degree in earth sciences or an associated discipline.
The project aims to: understand the magmatic processes and mechanisms of differentiation recorded in arc magmas and the relationships between crystal, melt and bulk rock compositions. We will specifically investigate the distribution of crystal populations across a range of lava compositions to better understand how intermediate magmas are formed by crystal mush formation, disaggregation and crystal entrainment. Results of the projects will contribute to better understand the mechanisms of continental crust formation and to bridge the gap between plutonic and volcanic rocks. This study will combine petrological observation and high resolution geochemical data with modelling.
Tasks will include:
- Bulk rock analysis of lavas by X-ray fluorescence
- Measurement of concentration profiles of major and trace elements in different minerals using electron microprobe and laser-ablation ICP MS techniques
- Diffusion modelling of the measured concentration profiles to obtain cooling rates
- Textural analysis of lavas
- Data interpretation and presentation of results in form of scientific publications
- A MSc degree or equivalent in earth sciences (or associated discipline)
- A strong interest in igneous petrology and analytical techniques
- Experience in electron microprobe analyses and/or laser-ablation ICP MS techniques are desired
- Good written and spoken English skills, and the motivation to work in an international team
- An interest in technical optimization of equipment and participation in development of analytical procedures
The position is funded for 3 years and will start on 01.03.2017 or later. Salary and benefits will be according to German Public Service Sector salary group TV-L 13, 75%. The PhD student will work on the project with Olivier Namur, David Neave and FranÁois Holtz. As an equal opportunity employer, the Leibniz Universitšt Hannover strongly encourages women to apply. Equally qualified disabled applicants will be given preference.
Application: Please send your application as a single pdf document (including motivation, CV, certificates, names of 1-2 referees) by email to Olivier Namur (firstname.lastname@example.org) before 20.02.2017. The review process will proceed until the position is filled.
