The
Institute of Mineralogy and Economic Geology at RWTH Aachen University invites
applications for a DFG-funded PhD position within a research project focussing
on the pressure-temperature-time-deformation evolution of high-pressure
metamorphic rocks in the Palaeoproterozoic Nagssugtoqidian Orogen in South-East
Greenland. The salary will be 75%TVL13.
The
Nagssugtoqidian Orogen is one of a few Palaeoproterozoic collisional orogens,
in which high-pressure metamorphic rocks have been preserved. Relict eclogites
and/or high-P granulites occur within mafic dykes in the orthogneiss-dominated
core of the orogen. Mineral assemblages of garnet and clinopyroxene as well as
clinopyroxene-plagioclase symplectites indicate PT-conditions outside the
plagioclase stability field. Preliminary work to this project indicates that
the rocks underwent retrogression at medium-to high-pressure granulite facies
grades, but it is currently unknown from which depth these rocks were exhumed.
In collaboration with the Geological Survey of Denmark and Greenland (GEUS),
the research will combine pressure-temperature-time paths obtained from
pseudosection modelling and U-Pb dating of minerals such as zircon, rutile, and
titanite with detailed kinematic investigations of shear zones to the north and
south of the high-P domain.
The
position will be for three years. Applicants should have a Master or equivalent
degree in Earth Sciences, a strong interest in phase diagram modelling and
geochronology, and the ability to conduct field work in the Arctic. The
appointment will start on the 1st of July 2013 or soon thereafter.
Applications,
including a curriculum vitae, a letter describing the research interests and
background, as well as the names and email addresses of two referees, should be
emailed as a single pdf-file by May 22 to:
Annika
Dziggel (adziggel@iml.rwth-aachen.de). Information about the Institute of
