The diversity and complexity of existing models on the structure of the Red Sea is the result of a mobile sedimentary cover that not only hides most of the basement and oceanic structures but also hamper the geophysical signals. In this study, we combined published with new unpublished geophysical data to propose a revised interpretation of the str...
Passive margin stratigraphy contains time‐integrated records of landscapes that have long since vanished. Quantitatively reading the stratigraphic record using coupled landscape evolution and stratigraphic forward models (SFMs) is a promising approach to extracting information about landscape history. However, there is no consensus about the optima...
Kinematic constraints on the Cenozoic deformation along the northwestern edge of the Tibetan Plateau remain limited. Combining surface geological data and seismic profiles, we document the structural geometry and kinematics of the large‐scale east‐west striking Hotan anticline, along the foothills of the Western Kunlun Range. Four new balanced cros...
Passive margin stratigraphy contains time-integrated records of landscapes that have long since vanished. Quantitatively reading the stratigraphic record using coupled landscape evolution and stratigraphic forward models (SFMs) is a promising approach to extracting information about landscape history. However, the most commonly used SFM, which is b...
Northern Red Sea coastal basins in Saudi Arabia are under favorable background conditions for geological CO2 storage, such as proximity to major CO2 emissions, favorable geothermal regime and seismicity. This study assesses CO2 storage potential in four major basins, including the Midyan, Ummluj, Yanbu and Jeddah basins. We identified major potenti...
The uplift of the southern African Plateau with its average elevations of ∼1,000 m is often attributed to mantle processes, but there are conflicting theories for the timing and drivers of topographic development. Evidence for most proposed plateau development histories is derived from continental erosion histories, marine stratigraphic architectur...
Paleogeographic maps are essential tools for understanding Earth system dynamics. They provide boundary conditions for climate and geodynamic modelling, for analysing surface processes and biotic interactions. However, the temporal and spatial distribution of key features such as seaways and mountain belts that govern climate changes and biotic int...
Les connaissances acquises sur l’exhumation de la chaîne pyrénéenne et l’évolution des bassins d’avant-pays adjacents permettent à présent d’appréhender ce système orogénique complexe dans une démarche intégrative dans l’espace et le temps.
Cette approche, dite « source-to-sink » s’attache à comprendre l’évolution du routage sédimentaire depuis la...
The French Massif Central is a key basement relief. This region experienced an intense period of alkaline volcanism, beginning with the Cantal Stratovolcano at 11 Ma and ending at 3 Ma. To quantify the palaeoelevation of the Cantal Stratovolcano and to replace it in the frame of the uplift history of the Massif Central, we first reconstructed the v...
The Cretaceous and Cenozoic fill of the continental margins of southern Africa (South‐East Atlantic and Agulhas Margins) contains a continuous record of sediment supplied from the South African Plateau for the past 134 million years. Estimates of solid sediment volumes deposited offshore were calculated from isopach maps and extrapolated vertical c...
The evolution and resulting morphology of a Cretaceous
contourite drift in the eastern Central Atlantic oceanic basin is
investigated in unprecedented detail using seismic imaging and agecalibrated
cross-margin sections. The margin, from the shelf, slope to
deep-water and abyssal plain is constructed by a succession of erosive
and depositional moun...
The aim of this study is to constrain the post-rift deformations of the Atlantic passive margin of Namibia and South Africa using an extensive industrial 2D reflection seismic dataset calibrated by wells and onshore outcrops that have been revaluated in age (biostratigraphy) in order to discuss the evolution of the South African Plateau uplift. The...
The south and southeast coast of southern Africa (from 28°S to 33°S) forms a high-elevated transform passive margin bounded to the east by the Agulhas-Falkland Fracture Zone (AFFZ). We analysed the stratigraphic record of the Outeniqua and Durban (Thekwini) Basins, located on the African side of the AFFZ, to determine the evolution of these margins...
There are two types of emerged relief on the Earth: high elevation areas (mountain belts and rift shoulders) in active tectonic settings and low elevation domains (anorogenic plateaus and plains) characteristic of the interior of the continents i.e. 70% of the Earth emerged relief. Both plateaus and plains are characterized by large erosional surfa...
Le plateau sud-africain (ou Kalahari) est le plateau anorogénique le plus grand au monde. Sa très grande longueur d’onde (×1000 km) et son altitude moyenne élevée (1000-1500 m) impliquent des processus mantelliques. La cinétique et l’origine de ce relief sont mal comprises. D’un côté, les études géomorphologiques le considèrent comme un relief mis...
New investigations carried out onshore Nacala in Mozambique prove the occurrence of Oxfordian to Kimmeridgian marine series. This series overlie an older series (Jurassic?) with a marked angular unconformity. These two units demonstrate the occurrence of a proto Mozambique marine channel West of the Davies Ridge and are in line with the results of...
The South African Plateau is formed by marginal bulges clustered around an intracontinental basin (the Kalahari Basin) with a mean elevation between 1000 and 1400 m. On seaward side, marginal bulges form major escarp-ments that can reach an elevation up to 3500 m in the Drakensberg area, boundering the high elevation continent from a dissected coas...
This paper reports observations carried out on Carboniferous to Permian sedimentary rocks in Moatize Basin in Tete Province. The outcrops of Vuzi, Moatize and Matinde Formations ranging in age from Late Carboniferous to Late Permian were logged and sampled along river sections. The Vuzi Formation is made up of diamictites with thin bedded sandstone...
L'évolution du plateau Sud-Africain (ou Kalahari), figure majeure du relief Sud-Africain, est très débattue. Il résulte d'au moins deux phases de surrection, une phase au Crétacé supérieur (Cénomanien terminal à Campanien) et une phase au Cénozoïque. L'âge de la surrection Cénozoïque et la cinétique d'érosion associée sont mal connues. L'objectif d...
Les marges d’Atlantique central en Afrique de l’Ouest sont des marges plates au relief peu marqué. Pourtant des études récentes de thermochronologie montrent d’importantes phases de dénudation (Bertotti et al., Int J Earth Sci, 2012) en amont de certaines de ces marges.
Cette étude est basée sur une analyse stratigraphique des principaux bassins cô...
We present new sedimentary flux data confirming that a large pulse of erosion affected the Southern African Plateau in the late Cretaceous and is likely to be related to a major uplift episode of the plateau. This short phase of erosion (i.e. less than 30 Myr in duration) has commonly been difficult to reconcile with a mantle origin for the plateau...
Present day central Atlantic margins of West Africa are flat margins with no significant reliefs onshore. Neverthe-less, recent thermochronological studies shows denudation, related to major vertical movements (Ghorbal et al., Terra Nova, 2008 ; Bertotti et al., Int J Earth Sci, 2012) along some parts of the margins. Using basin-scale regional sect...
INTRODUCTION
The spate of hydrocarbon discoveries in Rovuma Basin, Mozambique during the recent years have paved way for a framework of numerous petroleum systems. While the role of Tertiary and Mesozoic geological elements is well understood, the stratigraphic and tectonic framework of deeper Karoo sedimentary sequences has not been completely dec...
Middle Miocene remains of giant megatheriine ground sloths (Tardigrada: Megatherioidea) are scarce and generally located in southern South America. The discovery of a well-preserved edentulous dentary of Megathericulus sp. from the Middle Miocene (Laventan South American Land Mammal Age - SALMA; 13.5–11.8 Ma) of the Amazonian Peru increases our kno...
Siliciclastic sediment budget measurements was performed along the
margins and onshore basins of Africa for Cenozoic times. Our objective
was first to quantify the ratio between onshore and offshore sediment
preservation in the case of a relief with mostly no mountain belt and
secondly to understand the factors forcing the sediment supply along the...

Evaluation of geological CO2 storage potential in deep saline aquifer and depleted oil and gas reservoir in Saudi Arabia
This project aims at understanding the timeframe and amplitude of uplift and subsidence periods of the Arabian Plate. We use planation surfaces, weathering profiles, volcanism and stratigraphy as a proxy of these movements.
This work will focus on enhancing our understanding of the relationships between tectonic, climate, erosion and sedimentation of the Arabian Plate margins, impacted amongst other things, by mantellic deformations.
Focus will be made on the Cenozoic period and the opening of the Red Sea.
