The association of ultrapotassic rocks and shoshonites is common in the Alpine-Mediterranean region, with the exception of the Maghrebide Chain of Northern Africa, where only two small outcrops of ultrapotassic rocks have been documented. This study reports detailed field observations and new data on the petrology, mineral chemistry, whole-rock geo...
The western Mediterranean basin opened progressively from the Oligocene onwards, resulting in the partial inversion, subduction, and incorporation of the Tethyan margins into the Alpine Tell and Rif orogenic belts in North Morocco and Algeria. While proximal segments of these margins are accessible, the distal portions and the nature of the North A...
The utilization of optical satellite images has become instrumental in lithological and alteration assessments, enabling the differentiation of diverse circular structures. This study specifically focuses on mapping volcanic massifs in the Hoggar region using remote sensing techniques, with a strong emphasis on evaluating alteration degrees based o...
This richly illustrated book reviews the geology, tectonics, sedimentary basins and strategic resources of North Africa in 21 chapters. Chapter 1 is a regional synthesis. Chapter 2 examines the deep crustal and upper mantle structure. Chapter 3 compares the West African Craton. Chapters 4,5,6,7 deal with Pan-African-, Variscan (Hercynian)- and Alpi...
Circular structures are increasingly attracting attention as a fascinating research topic in Algeria. Studies have examined these features from different perspectives (Lamali et al., 2016, 2022; Hassani et al., 2016, 2024; Sahoui, 2024; Chabou, 2024), as their occurrence often indicates hypervelocity impact events (Lambert et al., 1981) or signific...
La Province Magmatique de l’Atlantique Central (CAMP), mise en place à la limite Trias/Jurassique, est la plus vaste province magmatique au Monde. Les témoins de cette province affleurent aujourd’hui en Afrique de l’Ouest, Amérique du Nord, Amérique du Sud et Europe. En Algérie, le magmatisme CAMP affleure dans les bassins du Sud-Ouest (Tindouf, Re...
The Azzel-Matti circular structure (25°51’ N, 0°35’ E) is located on the Tanezrouft plateau at the boundary between the West African Craton and the Bled El Mass compartment. Its morphology exhibits a diameter of about 6.5 km, with a raised rim that stands above the surrounding terrain. This study is based on a combination of remote sensing data (La...
A seismic section across the Talemzane crater (Algeria) reveals the presence of a narrow, disturbed zone just below the structure. The presence of this deep seismic anomaly seems to favour an endogenous origin (rising salt or gas) for this crater.
Along NW Africa, scarce relics of the Alpine Tethys crust are associated with the Maghrebian Flyschs. In the Rif belt, a string of potential relics extends as tectonic slivers within the stacked external nappes from the Beni Malek serpentinite massif to the Bou Adel gabbro massif. These relics define the transported “Mesorif Suture Zone” (MSZ), who...
The evolution of the Alpine Tethys margins during the beginning of the African-Eurasian convergence (Upper Cretaceous) was little studied compared to their evolution during the post-Pangea rifting and oceanic expansion, i.e., from the Early Jurassic to the Early Cretaceous. The aim of the present work is first to make up for this shortcoming in the...
From southern Senegal to northern Morocco, NW-Africa exhibits several poly-orogenic segments that registered the successive opening and closure of the Iapetus and Rheic (Proto-Atlantic) palaeooceans prior the breakoff of Pangea and the formation of the current Central Atlantic Ocean. This evolution was the founding example chosen by T. Wilson (1966...
The concept of cyclic closure and opening of oceans along the same crustal scar was introduced by J.T. Wilson (1966) based on the example of the Atlantic Ocean and its continental borders. At that time, the only Variscan orogen cited south of Europe along the Atlantic coast of Africa was the Mauritanides of Mauritania. Here we report on the recent...

On January 24, 2020, a Mw 5.0 earthquake occurred in the El Aouana region, northeastern Algeria. This region is located at the western end of the Lesser Kabylian Block (LKB), a rigid body that was weakly deformed during the late Cenozoic tectonic phase, and it is characterized by a lower seismic activity than that in its bounding regions. The mains...
Le bassin de Tindouf en Algérie a connu une intense activité magmatique datée de la limite Trias/Jurassique et appartenant à la grande province magmatique de l'Atlantique central (CAMP). Ce magmatisme s'est manifesté dans la région par la mise en place d'immense sills doléritiques au sein de la couverture paléozoïque du bassin et de longs dykes qui...

Primitive mafic rocks are of primary importance to constraint mantle source compositions and to modeling magma evolution processes. These rocks are thought to be generated by partial melting of a mantle source without modification by crystal fractionation, contamination or accumulation. Primitive mafic rocks are characterized by high MgO (or Mg#),...
Along NW Africa, scarce relics of the Alpine Tethys crust are associated with the Maghrebian Flyschs. In the Rif belt, a string of potential relics extend as tectonic slivers within the stacked external nappes from the Beni Malek massif (serpentinite, metabasalts and Jurassic-Cretaceous marbles) to the Kef-el-Ghar massif (gabbro, magmatic breccia,...
Exposed parts of the Central Atlantic Magmatic Province (CAMP) plumbing system, including huge doleritic sills and numerous dykes, are widespread in the northern flank of the Tindouf basin (Algeria). Doleritic pipes, that have never been studied so far, are spatially associated with these sills and dykes and thus supposed of CAMP origin. We present...

The Central Atlantic Magmatic Province (CAMP) is a major Large Igneous Province. Its formation coincides with the breakup of Pangea and the first opening stages of the central Atlantic Ocean. The CAMP consists of mafic rocks, often in the form of sills, dikes, and lava flows, which are spread across four continents (Africa, North America, South Ame...
Key Points
The main Mesorif gabbros emplaced in a Liassic oceanic domain and do not belong to the Central Atlantic Magmatic Province (CAMP)
CAMP dolerites may occur separately next to the oceanic gabbros in the structurally complex Mesorif zone
The prerift/synrift cover of the distal margin could have emplaced by gravity sliding onto the Mesorif oc...
Numerous mafic dykes, sills and laccoliths crop out in the southern part of the Tafilalt basin (Eastern Anti-Atlas, Morocco). These rocks intrude the mildly folded Ordovician to Early Carboniferous formations, consisting mainly of lamprophyric dolerites and camptonites with minor gabbros and syenodiorites. Previous geochemical studies have shown th...
The occurrence of serpentinites in the Oued Madagh area has long been known, but very few studies have been devoted to these rocks. The serpentinite massif crop out as tectonic lenses pinched in Paleozoic formations. Petrographical and mineralogical studies reveal the existence of a mineralogical assemblages of high-grade metamorphism (Chrysotile -...

Gara Djebilet iron ore, located in Southwestern Algeria near the border with Mauritania, is one of the most important iron ore deposit in Africa. The oolitic iron ore is interbedded within the Early Devonian (Pragian) sediments of the southern flank of the Tindouf basin. Remote sensing using the Landsat multispectral images provides an excellent to...
Introduction: According to the the Meteoritical Bulletin Da-tabase of the Meteoritical Society (June 2014), 739 classified me-teorites have been found in Algeria. Most of them were found in the Sahara, considered as one of the best areas in the world for recovering meteorites. We present here the discovery, classifica-tion and mineralogy of a new o...
It is generally believed that the first diamonds ever found in Africa were discovered in South Africa in 1867. Actually, three diamonds had already been found in 1833 near Constantine (Algeria). One of these, still preserved, shows radiohalos that suggest an old age. It could be a Sahara diamond reworked in more recent sediments, possibly the Oligo...
The aim of this study was to develop an index of water surfaces (IWS) for separating the water surfaces from other types of land use, by using the images of Landsat 7 ETM+. The index was applied on four areas characterized by different types of land use from different regions in Algeria. The first is from the center of Algeria (Landsat ETM+ scene:...
In 1833, Paolo Francesco Peloso, consul of Piedmont-Sardinia at Algiers, sold to the French three diamonds reportedly found by a "native" in the auriferous gravels of Oued Ghoumel, near Constantine. The find was presented at the Académie des Sciences and Société géologique de France, and the diamonds were purchased for three Parisian collections (É...
Algeria is the largest country in the African continent and contains a large number of sites
with geological and geomorphological interest. But till now, the Algerian geoheritage is poorly known
and these sites need to be inventoried, protected and enhanced for education, tourism and scientific
purposes.
We initiated a project named “GeoAl” whose m...
La création et la gestion de bases de données est devenue une nécessité aussi bien pour la recherche fondamentale que pour la recherche appliquée, particulièrement la géologie minière ou la gestion des risques naturels. Par ailleurs, l’Algérie dispose actuellement d’une importante quantité d'informations géologiques (cartes géologiques, analyses gé...
In south-western Algeria, dolerite sills and dykes and scarce basalt lava flows occur in the Tindouf, Reggane, Hank basins and Bechar area, and are part of the large Central Atlantic Magmatic Province (CAMP). They represent the north-easternmost witnesses of this province into the African continent. Here, we report the first geochemical data (major...
40Ar/39Ar step-heating analyses performed on plagioclase separates from seven doleritic basalts (four sills, one dyke and two lava flows) from southwestern Algeria display disturbed age spectra, reflecting various contributions of alteration by sericite and/or excess argon. Weighted mean ages corresponding to the less altered plagioclase fractions...
