Host institution

The “COMUE Bourgogne Franche-Comté” (UBFC) is a community of universities and higher education institutions (“COMUE”) federating six higher education and research institutions operating in the Bourgogne Franche-Comté region. UBFC gathers around 8740 personals among which 2066 assistant professors/professors and 264 permanent researchers, and welcomes around 56000 students every year. Within UBFC, the Université de Bourgogne (“UB”) will be responsible for hosting and training the PhD student, at the Biogéosciences research unit. The Biogéosciences research unit is a research community currently comprising more than 100 members, including full-time researchers from the CNRS (French national centre for scientific research), assistant professors and professors from the Université de Bourgogne and from the EPHE (École pratique des hautes études), technical staff, post-doctoral fellows, PhD students and invited researchers. Biogéosciences is built around five interacting research teams whose scientific activities are deeply anchored into the fields of sedimentology, geochemistry, climatology and paleoclimatology, palaeontology, environmental sciences, and evolutionary ecology/biology, helped by a multitude of analytical, administrative and logistical services. The Sedimentary Systems, Environments and Dynamics (SEDS) group of Emmanuelle Pucéat, Pierre Pellenard, and Emmanuelle Vennin is highly recognized for its expertise in Cretaceous and Jurassic paleoclimate evolution and interaction with sedimentary systems. This group hosted several projects funded by the French national research agency (ANR) along with European H2020 projects centered on the long-term evolution of the climate system based on a combination of geochemical and sedimentological approaches, and has strong connections with Energy companies (EDF/GDF, TOTAL).

Research objectives

The major uplift phase encountered by South Africa during the late Cretaceous leaded to a drastic increase in the denudation rates of the south African margin, associated to large sediment accumulation rates offshore. This event provides a unique opportunity to explore the long-term response of chemical weathering and of erosion to intense tectonic uplift within a greenhouse climate. The respective importance of these two processes in the evolution and distribution of detrital fluxes and in the formation of reservoirs is a key question that still remains to be elucidated, especially in such active tectonic context where denudation rates and weathering rates can become decoupled. The PhD student will apply here a novel geochemical approach, combining clay mineralogical analyses with clay Nd and Hf isotope composition (ΔεHf), to (1) decipher the respective evolution of chemical weathering and erosion during the late Cretaceous uplift of South Africa, (2) tackle the links between these two processes and the evolution and distribution of detrital fluxes in this tectonic setting, and (3) explore the potential impact of this uplift on late Cretaceous climate evolution, through CO2 consumption by silicate weathering reactions.

Presentation of the research project (cooperative aspect)

This PhD position is within the framework of a European ITN project named S2S-FUTURE: SIGNAL PROPAGATION IN SOURCE TO SINK for the FUTUre of earth Resources and Energies involving 15 PhD positions.

To meet the challenging objectives of this project, both ODP/DSDP cores (360, 361) offshore and cores onshore from the Geological Survey in the Cape Basin/Orange Basin region have been targeted, with sediment accumulation rates already available, that will be used to capture the respective role of weathering and erosion changes in the evolution and distribution of sediments offshore. Under the supervision of Emmanuelle Pucéat (Assistant Professor, Université Bourgogne Franche-Comté, UMR CNRS Biogéosciences) and Pierre Pellenard (Ass. Prof., Université Bourgogne Franche-Comté, UMR CNRS Biogéosciences ), the PhD student will determine mineral assemblages and analyze the neodymium and hafnium isotope composition of sediment clay fractions to reconstruct the evolution of chemical weathering and mechanical erosion during the late Cretaceous at the different targeted sites, located in the vicinity of an uplifted margin of Africa. The novel data acquired will bridge a gap in our understanding of the links between tectonic and climate.

The PhD student will actively collaborate with other French and European institutions, including required research stays (secondments ) at the Université de Rennes 1, France (Prof. François Guillocheau ; 8 months), GFZ-Potsdam,Germany, (Prof. Jean Braun, 1 month) and TOTAL S.A., France (Dr. Charlotte Fillon ; 1 month).

The PhD student will be also involved in scientific/soft-skills meetings and in research activities conducted in other laboratories/companies from Europe and associated countries.

An important component of the training will be the participation to 3 main major “Summer Institutes”:

Summer 2020 (postponed to 2021 due to sanitary crisis): “Dragonstone” – South-Pyrenees Spain and France: an innovative combination of field excursion and computer modeling of surface processes from source to sink.

Summer 2021: “The Factory” – Norway, Great Britain and Switzerland: field visit of modern S2S systems and course intensive program program of technical and soft skills to accelerate the students’ research, write and present their results, consolidate their profiles and develop concrete plans for their future.

Summer 2022: “Inside Africa” – South-Africa: an immersion of ESRs in the modern source-to-sink system of a continental-scale large river, the Orange in Southern Africa, with high economic implications for mining industries.

In addition to these major milestones of the program, the PhD students will 1) continuously develop their core research skills via their own research project locally and within the network while at secondments and conferences, 2) receive a mandatory amount of hard and soft-skills training specific to their own doctoral school, along with mentoring by joint supervising bodies, 3) use EGU conferences both as dissemination events for ESRs results and network events for progress reports and evaluations, and 4) collaborate into practical activities aimed at network-structuring legacy deliverables.

The goal of S2S-FUTURE is to understand, quantify and model the sediment routing system from the sediment production (source) to the sediment deposition (sink); its tectonic and climatic controls; and to establish generic rules for a full understanding of signals propagation in S2S systems for building predictive models of sediment location and characteristics. These studies of S2S systems require interdisciplinary approaches combining geomorphology, sedimentology and stratigraphy, geochemistry, tectonic and paleoclimatology coupling observations, quantifications and process modelling. All these skills are integrated in the S2S-FUTURE project.

The objectives of S2S-FUTURE have been designed with primary societal implications in the domains of water, carbon-derived energy, sustainable geological energy and geological storage of non-geological energy, waste geological storage, mineral resources, and building materials. These points have become crucial for sustainable investment and development according to several of the United Nations Sustainable Development Goals such as SDG#6 (Clean water and sanitation), SDG#7 (Affordable and clean energy) and SDG#13 (Climate action) among others.
