The Laboratoire des Fluides Complexes et de leurs Réservoirs (http://lfc.univ-pau.fr/fr/index.html), in the Université de Pau et des Pays de l’Adour, offers a fully funded 3 years PhD position in structural geology, focusing on the use of paleopiezometry to assess temporal and spatial stress compartmentalization in a carbonate fold-and-thrust belt. The position is part of the isite-E2S consortium (http://e2s-uppa.eu/en/index.html) opens from September 2018 and will remain opened until filled. The investigators are seeking for a motivated and talented geologist that will benefit from an enticing research environment that values both academic and industrial, problem-solving research with cutting-edge equipment and methods.
This PhD subject will focus on reconstructing the successive stress tensor in several structures along a transect in a carbonated fold-and-thrust belt, by combining a structural and microstructural approach to paleopiezometer such as the stylolite roughness inversion technique and the calcite stress inversion technique. The target for this study is the Umbria Marches fold-and-thrust belt, in the central Apennines (Italy). This active arcuate belt underwent a complex sequence of compressional deformation (thin- then thick-skinned) that is imprinted in the competent Jurassic-Cretaceous limestones as fractures and stylolites. These limestone host numerous stylolites, both of tectonic and sedimentary origins, allowing to reconstruct the successive stress magnitude and regime experienced by the strata from the hinterland to the foreland. To reconstruct the deformation sequence and related stress evolution will help to unravel questions about (1) the stress compartmentalization at fold and fold-thrust belt scale, (2) the effect of structural style on stress level in the crust, and (3) the share of deformation mechanisms in stress accommodation (brittle fracture vs ductile pressure solution).
The successful candidate is expected to have a MsC, a solid background in structural geology, and a developed interest for signal analysis or physical statistic. An interest in computing techniques (Matlab, image analysis) and/or diagenetic studies for fracture infill analysis are a bonus.
The successful candidate will be part of the research team of the Laboratoire des Fluides Complexes et de leurs Reservoirs, in UPPA, on the campus of Pau. The candidate will potentially specifically interact with ongoing projects within the LFCR, and benefit from the dense international, interdisciplinary network of E2S. The PhD position involves a mandatory teaching in class (32h per year), and a training program to design with the supervisors. Gross salary is 1878€/month before tax.
Applicant must provide, before the deadline, a CV, cover letter, master degree transcript and ranking, reference letter, and contact details for minimum two relevant professional for further reference.
Submission deadline: 10th of May 2018
