Monsoonal imprint on late Quaternary landscapes of the Rub’ al Khali Desert Open
Abundant geomorphological, biological, and isotopic records show that Arabia repeatedly underwent significant climate-driven environmental changes during late Quaternary humid periods. Precisely mapping how the enhancement and expansion of…

Evolution of carbonate platforms in the northeast Red Sea during the last 23 million years Open
The Midyan Peninsula between the northern Red Sea and Gulf of Aqaba is the only place along the Red Sea where Lower to Middle Miocene syn-rift sedimentary strata (Aquitanian to Langhian) are continuously exposed, including exceptionally pr…

Evolution of the Eastern Red Sea Rifted margin: morphology, uplift processes and source-to-sink dynamics Open
This paper explores the formation and evolution of high-elevation passive margins, focusing on the morphology and uplift processes of the eastern Red Sea region and its relationship to the stratigraphy of the Red Sea (source-to-sink approa…

The tectonostratigraphic latitudinal record of the eastern Red Sea margin Open
We characterize the eastern Red Sea necking crustal domain through its north-south structural and stratigraphic record. Along-strike margin segmentation occurred during rifting (∼28-14 Ma), with tilted blocks filled by siliciclastic sedime…

Structure and fracture characterization of the Jizan group: Implications for subsurface CO2 basalt mineralization Open
The coastal region of southwest Saudi Arabia contains a thick sequence of Late Oligocene basalts in the Jizan Group, which accumulated along the continental rift that preceded the opening of the Red Sea. These basalts are targeted for the …

Linking uplift, erosion, and sedimentation using landscape evolution models: Madagascar since the Late Cretaceous Open
Summary We present a study to estimate the large‐scale landscape history of a continental margin, by establishing a source‐to‐sink volume balance between the eroding onshore areas and the offshore basins. Assuming erosion as the primary pr…

Tectonic control on the reef evolution in the Red Sea syn-rift basin Open
<p>Fossil carbonate reefs are common along rifts and rifted passive margins. They provide valuable paleoecological and paleogeographical information. Moreover, porous reef buildups are targeted as potential oil and gas reservoirs and…

Structure and Morphology of the Mid-Ocean-Ridge in the Red Sea Open
<p>This presentation describes the structure and morphologies associated with seafloor spreading in the Red Sea inferred from bathymetric, gravity, magnetic and seismic data. We show that the orientation of the structures is consiste…

Tectonic, magmatic and sedimentary evolution of the strike-slip margins of eastern Austral Africa (Mozambique Channel): palaeogeographic constrains Open
<p>The geological evolution of the Mozambique Channel sensu largowas controlled by three major transfer zones (Davie, Mozambique and Agulhas/Falklands), (1) related to the migration of four continents (Africa, Madagascar, Antarctica,…
