As global energy demands continue to increase, the construction industry,
known for its high energy consumption, is in greater need of materials that
are both lightweight and thermally efficient. Porous bricks were elaborated
using organic waste additives to explore the relationship between compressive strength (CS) and thermal performance. To dete...
The Oued Guir watershed in southeast Morocco stretches widely from the High Atlas in the north to the Hamadas in the south. This basin is characterized by an arid climate strongly influenced by continental conditions. The Lower Guir has become a focal point for the development of modern agriculture following the launch of the Green Morocco Plan. Th...
The Wadi Guir Watershed, located in the eastern basins of Morocco, spans approximately 4,231 km². One of the major challenges both globally and in Morocco, particularly in oasis regions such as the Guir River watershed, is ensuring water availability while preserving ecosystems in arid zones affected by climate change. This challenge is further com...
The Rheris oases in Southeastern Morocco are an essential ecosystem. It presents enormous ecological and natural values. Water scarcity coupled with agricultural intensification results in soil salinization and its degradation. This work aims to propose a spatiotemporal monitoring method of soil salinization in the Rheris oasis using spectral indic...
The development of impoverished and marginalized communities is being increasingly jeopardized by the risks associated with climate change. Extreme weather events, like floods, can impact infrastructure, ecosystems, agriculture, water, and other vital sectors. Our study focuses on the flood risk in Aït Athmane, located 28 kilometres north of Errach...
The risks associated with climate change are increasingly threatening the development of poor and marginalized populations. Extreme climatic events like floods can affect vital sectors such as water, agriculture, infrastructure, and ecosystems. Our study focuses on the risk of flooding in Aït Athmane, located 28 km north of Errachidia, Morocco. Thi...
Erosion represents a significant environmental challenge in southeastern Morocco. This arid and semiarid region experiences notably heavy rainfall, followed by prolonged periods of drought. This alternation of climate events creates an accelerated erosion cycle that affects fragile soils. The present work aims to apply existing models and analysis...
This study presents a comprehensive groundwater vulnerability assessment conducted in the Goulmima palm grove of southeastern Morocco, a region facing potential risks of groundwater pollution due to natural and anthropogenic factors. In this study, the DRASTIC and GOD methods were used to identify areas highly, moderately, and weakly vulnerable to...
The Ferkla Oasis is situated in the Rheris watershed in the southeast of Morocco, between the eastern Anti-Atlas in the south (Ougnat inlier) and the Central High Atlas in the north. This oasis is characterized by a semi-desert climate with strong continental influence, marked by low and irregular rainfall and high temperatures. This oasis has expe...
In the Ferkla Oasis, much like in numerous other oases across the southeastern region of Morocco, a range of socio-economic and environmental challenges are intricately linked to the inadequate management of water resources. One proposed remedy to address these concerns is the implementation of artificial aquifer recharge, which stands as an altern...
Six lithostratigraphic sections distributed in different parts of the Errachidia-Boudenib-Erfoud basin (SE Morocco) were surveyed bed by bed and sampled in order to study stratigraphy, analyzed the facies, and characterized the depositional environment of the Senonian series. This study shows that this series is mainly constituted of three lithostr...

This oasis is characterized by a semi-desert climate with strong continental influence, marked by low and irregular rainfall as well as high temperatures. This oasis h...
Ce travail présente une létude lithostratigraphique, sédimentologique et structuro-géodynamique des "couches rouges" jurassico–crétacées du Haut Atlas Central. Dix coupes détaillées levées dans différentes régions du domaine montrent des dépôts de plus en plus grossiers en allant du centre vers les bordures du bassin. Les épaisseurs totales de la s...
In the southeast of Morocco, water erosion constitutes the origin of many geo-environmental and socio-economic problems that stress the ecosystem and negatively impact the water harvesting structures. The goal of this work is to apply a new model for assessing water erosion vulnerability and choosing possible locations for erosion control implement...
La coupe d'Aït Athmane est située dans la partie sud-est du Haut Atlas central, à environ 20 km au nord d'Er-rachidia. Sa série toarcienne, formée de marnes silteuses et de marno-calcaires, est riche en Brachiopodes (rhyn-chonellidés et térébratulidés) dans sa partie inférieure, Toarcien inférieur (Zone à Levisoni ?) et moyen (Zones à Bifrons et Gr...
In the Amellago area (central High Atlas), the widely distributed Toarcian succession consists of marl and marly limestones of the Tagoudite and Agoudim formations. We here describe, for the first time, the ammonites of the Polymorphum Zone from the Tagoudite Formation, including Canavaria cf. rosenbergi Fucini, C. aff. zancleana (Fucini), Dactylio...
Ten detailed sections have been logged and studied from the “Infra-Cenomanian’’ to the Cenomanian–Turonian deposits in the Errachidia–Boudnib–Erfoud Basin between Tazzouguerte and Anounizme(SE Morocco). They show variations in their lithology and microfacies that reflect changes in the depositional environment from the base to the top of the sedime...
Résumé
Dans le Haut Atlas central, l’étage Toarcien est représenté par une série marneuse et marno-calcaire d’épaisseur variable. Deux coupes ont été étudiées : Amellago (500 m) et Aït Athmane (100 m). Les ammonites récoltées dans les deux coupes ont permis de caractériser les zones à Polymorphum, Levisoni, Bifrons, Gradata et Speciosum. La zone à...
The red detrital formations of the Central and Eastern High Atlas of Morocco continue to spark a large scientific debate around their age varying from the middle Jurassic to the upper Cretaceous period. Through this paper, we present the results of lithological correlations of five detailed geological sections, covering the Jurassic–Cretaceous “red...
Les granulites de Béni Bousera forment un massif exceptionnel affleurant au sein du
domaine interne du Rif. Ses spécificités particulières et complexes ont souvent intrigué la
curiosité des géologues sur ses origines et sur le contexte géodynamique responsable de sa
formation et de son exhumation. En effet, les données structurales, microstructural...

La compréhension des processus orogéniques nécessite l'acquisition de données permettant de suivre les variations de pression (P), température (T) et déformation (D) au cours du temps (t). La construction de trajets P-T-D-t devrait impliquer une approche pluridisciplinaire, qui combine une analyse pétrologique et structurale à l'acquisition de donn...
Les granulites du massif de Béni Bousera appartiennent au domaine interne de la chaîne alpine du Rif.
L’approche pluridisciplinaire de la géologie structurale, microstructurale et pétrographique de celles-ci permettent de mettre en évidence différentes phases de déformation.
Les granulites de Béni Bousera montrent un excellent registre géologique q...
Le bassin crétacé d'Errachidia (Sud-Est marocain) est connu par sa puissante série d'épaisseur variable et sa richesse paléontologique qui reflète une biodiversité et un paléoenvironnement assez variés. La série crétacée est classiquement subdivisée en trois Formations : la Formation d'Ifezouane attribuée à l'Albien ; la Formation d'Aoufous rapport...
Seven sections, covering the upper Albian to lowermost Turonian, have been correlated from full-marine to continental-dominated deposits across a passive margin, along a transect 425 km long, from the present-day Atlantic coast to the “Pre-African Trough” between the Anti-Atlas and the High-Atlas. The thickness of the Cenomanian succession changes...

Sur l'ensemble du segment Ifni-Tarfaya de la côte atlantique marocaine (Fig. 1), des dépôts fluviatiles se mettent en place sur la plate-forme carbonatée marginale jurassique. Ces dépôts atteignent une épaisseur de l'ordre de 1300 mètres (forage de Puerto-Cansado). Ils passent en offshore (forage Tan-Tan), à une série marine à caractère peu profond...
