The Tibesti massif, one of the most prominent features of the Sahara desert, covers an area of some 100,000 km2. Though largely absent from scientific inquiry for several decades, it is one of the world’s major volcanic provinces, and a key example of continental hot spot volcanism. The intense activity of the TVP began as early as the Oligocene, though the major products that mark its surface date from Lower Miocene to Quaternary (Furon (Geology of Africa.

Central volcanoes and caldera collapses in the late Miocene – Late Pleistocene Tibesti Volcanic Province, northwest Chad
Abstract The Tibesti Volcanic Province (TVP) in northwest Chad represents the second largest of the five Gharyan–Tibesti volcanic provinces and covers an area around 29,000 km2. The other fourExpand
The Cenozoic volcanic province of Tibesti (Sahara of Chad): major units, chronology, and structural features
Using both field relationships and some absolute ages, the sequence of volcanic units in the Cenozoic Tibesti Volcanic Province (TVP) (Chad) is established as follows: (1) plateau volcanism, betweenExpand
Relationships between structural lineaments and Cenozoic volcanism, Tibesti swell, Saharan metacraton
Abstract This work reports an analysis of the relationships existing between the structural lineaments and the Cenozoic volcanism of the Tibesti area (northern Chad). Shield volcanoes, cinder cones,Expand
Quantifying Asthenospheric and Lithospheric Controls on Mafic
19 African basin-and-swell morphology is often attributed to the planform of sub-plate 20 mantle convection. Across North Africa, the coincidence of Neogene and Quaternary (i.e. 21 < 23 Ma)Expand
The African Landscape Through Space and Time
It is generally accepted that Cenozoic epeirogeny of the African continent is moderated by convective circulation of the mantle. Nevertheless, the spatial and temporal evolution of Africa'sExpand
Quantifying Asthenospheric and Lithospheric Controls on Mafic Magmatism Across North Africa
African basin-and-swell morphology is often attributed to the planform of subplate mantle convection. Across North Africa, the coincidence of Neogene and Quaternary (i.e., <23Ma) magmatism,Expand
Sedimentary provenance and maximum depositional age analysis of the Cretaceous? Lapur and Muruanachok sandstones (Turkana Grits), Turkana Basin, Kenya
Abstract The Turkana Basin of northwestern Kenya is well known for its rich Neogene–Quaternary vertebrate fossil record; however, it also represents one of the few locations in sub-Saharan AfricaExpand
The Jebel Hadid structure (Al Kufrah Basin, SE Libya)—A possible impact structure and potential hydrocarbon trap?
Abstract The Jebel Hadid structure that formed in the Nubian Sandstone of the southern Al Kufrah Basin is a ∼4.7 km circular feature with a set of multiple concentric annular ridges. The age of theExpand
Primary Volcanic Landforms
Abstract Volcanic landforms on the Earth range are shapes and sizes from tiny scoria cones to enormous flood basalt or ignimbrite plateaux. Controls on the final volcanic landform include magmaExpand
Plate kinematics and geodynamics in the central Mediterranean.
Abstract We argue that seismotectonic activity in the Central Mediterranean area and the Aegean–Balkan zone is driven by the NNE-ward motion of Africa and westward motion of Anatolia with respect toExpand
