SOURCE TO SINK – S2S

Investigating the sediment routing from mountain belts to passive margins
A Sediment-routing-system-scale vision to quantify and predict sediment transfers and deposition

Introduction

In the  S2S  project, we use a combination of methodologies to bring quantifications on erosional, transfer and depositional processes such as seismic stratigraphy analysis, geomorphology, low-temperature thermochronology, geochronology, datation methods of weathering products, facies sedimentology and numerical modeling.

Presentation

The project addresses several thematics:

  1. S2S peri-Pyrenees: Sediment routing system in an orogenic context, including the Pyrenees and its two forelands as well as the Bay of Biscay area;
  2. S2S Far-field: the geologic record of the stress transmission across the European plate linked to the orogenic wedge dynamics;
  3. S2S Guiana shield: Sediment routing system in the Guyana shield and its Atlantic margin;
  4. S2S new methodologies: New methodological constraints on weathering development.

These research axis aim at qualifying and quantifying the processes responsible of sediment transfers, whether they are of tectonic or climatic origin, in the framework of the Pyrenees-Aquitaine and the Guyana shield Source-to-Sink system.  With this approach, we bring keys to identify the causes of sediment transfers as well as elements of predictions on qualities and quantities of sediment exported from the Source to the Sink.

Our organisation

The S2S research project is a partnership between the BRGM (French geological survey) and Total S.A. R&D department with the strong involvement of academic institutes.

The Project is divided into 2 research blocks powered by 3 Academic scientific leaders:

S2S “compressive context” team deals with sediment routing system in the Pyrenean and West-european framework. Scientific lead is carried by Pr. Sebastien Castelltort (Univ. Genève), Eric Lasseur (BRGM) and Charlotte Fillon (Total). It implies 3 Phd students and 5 post-docs, located in Rennes, Paris-Saclay, Genève and Namur universities.

S2S Compressive context

S2S “Guyane” team is developing a qualitative and quantitative S2S study of the Guiana shield and its Atlantic margin in the geodynamic framework of the South American plate. The scientific leaders are Delphine Rouby (GET Toulouse), Cécile Gautheron (Univ. Paris Saclay), Jean Yves Roig (BRGM) and Massimo D’all Asta (Total). 1 PhDs and 2 post-docs were involved in this project in Toulouse and Paris-Saclay universities.
