ESR4

PhD position in experimental petrology

Marie-Curie Initial Training Network ABYSS (ESR4)

Training network on reactive geological systems from the mantle to the abyssal sub-seafloor

Host Institution: Leibniz Universität Hannover (Germany) / Secondment institutions: Università Degli Studi di Milano (Italy), University of Southampton (UK)

The Institute of Mineralogy at the Leibniz University of Hannover seeks to appoint a PhD student for a research project in petrology with the main focus on experimental investigation of the interactions between rock and a fluid strongly enriched in NaCl (brine) derived from hydrothermal fluids at very high temperatures. The experimental work uses state-of-art high-pressure facilities in two different labs at the University of Hannover (J. Koepke) and the University of Milano (P. Fumagalli). This project will also investigate chlorine-rich mineral phases from natural abyssal gabbros which are discussed to be formed by rock/brine interaction in the deep crust under mid-ocean ridges. Isotope analysis of these mineral phases will be performed at the University of Southampton (D. Teagle).

Methods: Experiments in Internally Heated Pressure Vessels (IHPV, P ≤ 0.5 GPa); experiments with piston cylinder techniques (U. of Milano, P ~ 0.5-1 GPa); analysis of the experimental results with in-situ geochemical methods (EPMA; LA-ICP-MS); bulk and in situ geochemical analysis of natural hydro-magmatic minerals from deep oceanic crust and shallow mantle with special focus on fluid-mobile trace elements; stable isotope analysis (U. of Southampton).

Requirements: Candidates must hold a MSc in Earth Sciences or a closely related discipline. Experience in petrology and analytical lab work is absolutely necessary.

This fellowship is for a period of 36 months starting no later than November 1, 2014.
