PhD position on melt-rock interactions in the oceanic lithosphere
Marie-Curie Initial Training Network ABYSS (ESR2)
Training network on reactive geological systems from the mantle to the abyssal sub-seafloor
Host institution : Dipartimento di Scienze della Terra, dell’Ambiente e della Vita, Università degli Studi di Genova (Italy) / Secondment institutions: Géosciences Montpellier (CNRS, France), National Oceanographic Centre, University of Southampton (UK).
The Department of Earth, Environment and Life Sciences at the University of Genova seeks to appoint a PhD student for a research project in igneous petrology and rock-forming processes in the lower oceanic crust. Field objects will be fossil oceanic lithosphere records in the Alpine-Apennine ophiolites (Liguria, Alpine Corse). The ESR will work in a multidisciplinary environment, in collaboration with E. Rampone, L. Crispini (Università degli Studi di Genova), M. Godard, B. Ildefonse (Geosciences Montpellier) and D. Teagle (University of Southampton).
Methods: Field mapping, Microstructural analysis (EBSD), Imaging (SEM), In-situ mineral chemistry (EMPA, LA-ICP-MS), Elemental mapping, Geochemical modelling.
Goals: Define field relations of crustal rocks and host mantle peridotites, to constrain styles and mechanisms of magma intrusion. Provide geochemical and microstructural tools to constrain the origin (mantle vs. magmatic) of olivine in the lower oceanic crust, and determine the role of fractional crystallization and reactive porous melt flow. Understand the effect of melt-rock reaction in the lower oceanic crust on the evolution of MORBs.
Requirements: Candidates must hold an MSc in Earth Sciences or a closely related discipline. Background in mapping and structural analysis, petrology, geochemistry is advantageous. Solid grounds in physical sciences are welcome.
This fellowship is for a period of 36 months starting no later than November 1, 2014.
