Tracing trajectories and geochemical evolution of subducted oceanic lithosphere

PhD position in petrology and geochemistry of high-ultrahigh pressure rocks and fluids

Main host institution: Dipartimento di Scienze della Terra, Ambiente e Vita, Università di Genova, Italy
Secondment Institutions: University of Bern; Deutsches GeoForschungs Zentrum, Potsdam

The Department of Earth, Environmental and Life Sciences at the University of Genova seeks to appoint a PhD student for a research project in petrology and geochemistry of high-pressure rocks and fluids. The successful applicant will work in a multi-disciplinary environment in close collaboration with Profs. Marco Scambelluri, Klaus Mezger and Sonia Tonarini.

The ESRs will work on plate interface examples exposed in high- and ultrahigh-pressure mountain belts and determine the petrological/geochemical features of rocks and of fluid-related structures. Main objects are oceanic crust, serpentinized upper plate mantle and continental materials of the Alps evolved along a fossil plate interface. These will be compared with occurrences from other settings.

Methods: Field mapping; petrology/geochemistry of rocks/minerals; stable (O, H, Li, B) and radiogenic (Sr, Pb) isotope analyses coupled with new geochemical tracers (As, Sb); modelling of fluid/rock exchange.

Goals: Defining petrological and geochemical identity of plate interface settings, assessing rock diversity and paths, fluid-rock interactions and mass transfer from micro- to mega-scales along the plate interface.

Candidates must hold an MSc in Earth Sciences or a closely related discipline. Experience in petrology, geochemistry, structural geology is highly advantageous

Genova is a livable city on the NW coast of Italy. During the PhD, the candidate will collaborate with M. Scambelluri (Genova) for the petrology and structure of high-P rocks, will work with S. Tonarini (isotope laboratories in Pisa), and will collaborate with K. Mezger, S. Angiboust, A. Garcia Casco in the secondment Institutions.

Expected starting date: between January and May 2014.

Deadline for application: November 13th, 2013.
