Missions

General context of the project
The Gondwana breakup between South America and Africa still bears many open questions related to the tectonic, magmatic, sedimentary and palaeoceanographic/climatic evolution that led to the formation of the South Atlantic Ocean. Unravelling the interaction between these different processes during the Gondwana breakup and the way these processes were recorded in the syn-breakup sedimentary sequence is of key importance to understand the formation of oceanic gateways, which had a major impact on the paleo-oceanographic/climatic evolution. However, how climate, depositional environments and the thermohaline circulation are linked to the tectono-volcanic activity during breakup remains to be investigated. In this project we study the Early Cretaceous Gondwana breakup by focusing on the Austral segment of the South Atlantic. This mega event has become increasingly discussed in the last decade, not only in the academic community, but also in industry, due to the hydrocarbon richness of the syn-rift sedimentary sequences.

Activities

Research project:
The origin and evolution of the South Atlantic still bears many open questions in terms of rift evolution, compartmentalization, as well as palaeo-oceanographic/climatic evolution during volcanic breakup leading to the formation of new oceanic gateways. Our project aims to investigate the Lower Cretaceous syn-breakup phase along the Austral segment of the South Atlantic through a correlation of the syn-breakup sedimentary sequence across the conjugate margins. The main question addressed in our project focuses on how depositional environments are linked to the paleo-climatic and tectono-volcanic activity during breakup. To answer to this question, three main tasks are proposed:
1. describe and discuss possible causes for the asymmetry evolution between the syn-breakup sediments from the conjugate margins
2. describe and characterize the nature and architecture of the sedimentary deposits just above the seaward dipping reflectors (SDR) on the two conjugate margins
3. recognize and discuss paleogeographic and paleoclimatic events (regional vs global) and how they affected the sedimentary record.

Skills

This work will be based on the study of seismic sections and well data using petrophysical and micropaleontological approaches and a seismic interpretation software. The results will be published in peer-reviewed international journals.

Work Context

The successful candidate will work in the “Institut Terre et Environnement de Strasbourg” (ITES) and integrate the Geology team, well known for its work on rifted margins. The project includes collaborations with researchers in France and abroad. The project will be supervised by Gianreto Manatschal.
