Provenance and Geotectonic Setting of the Ourika Gneissic Rocks (High-Atlas, Morocco)

Ahmed Barakat Mohamed El Baghdadi Jamila Rais

ii) The GBA and GAA protoliths that have until now been regarded as the PI terranes by many previous works, belong to a Pan-African orogeny. The GBA protholith seem to be generated by the melting of the crustal or immature sedimentary rocks after crustal thinning during the earlier Pan- African orogenic events, at c. 780 to 750 Ma. GAA protolith were formed in Panafrican island arc/fore-arc basin environments, at c. 743 Ma, from an anatexie related to the mantellic injection in the juvenile continental crust. iii) The two gneissic protoliths have been affected by an amphibolite to granulite-facies metamorphism (700±50°C) during the earlier Pan-African orogenic event and by a greenschist-facies metamorphism (570±30°C), very developed in GBA protolith, during the late Pan-African orogeny. iv) The strong N-S gradient of Pan-African deformation would be thus responsible for the overlapping of the GBA on the GAA protolith as well as for the dome shape of the Ourika gneisses. The dome core corresponding to the GBA gneisses which has been srongly affected by this deformation, would have intruded, by ascending movements convectifs, in the heavy cover formed by the GAA gneiss.

Assessment of spatial and seasonal water quality variation of Oum Er Rbia River (Morocco) using multivariate statistical techniques

International Soil and Water Conservation Research (2016)

Ahmed Barakat Mohamed El Baghdadi Jamila Rais Brahim Aghezzaf Mohamed Slassi

The aim of this study is to assess the spatial and temporal water quality variation and to determine the main contamination sources in the Oum Er Rbia River and its main tributary, El Abid River. The water quality data were collected during 2000–2012 from fourteen sampling stations distributed along the river. The water quality indicators used were TEMP, pH, EC, turbidity, TSS, DO, NH4+, NH3–, TP, BOD5, COD and F. coli. The water quality data was analyzed using multivariate statistical methods including Pearson's correlation, PCA, and CA. The results showed that in some stations the water quality parameters were over Moroccan water standards. PCA applied to compare the compositional patterns among the analyzed water samples, identified and four factors accounting for almost 63% of the total variation in the data. This suggests that the variations in water compounds’ concentration are mainly related to point source contamination (domestic and industrial wastewater), non-point source contamination (agriculture activities), as well as natural processes (weathering of soil and rock). CA showed relatively spatial and seasonal changes in surface water quality, which are usually indicators of contamination with rainfalls or other sources. Overall, this study showed that the water was potentially hazardous to health of the consumers and highlighted the need to treat industrial and municipal wastewater and to encourage sustainable agricultural practices to prevent adverse health effects. We therefore suggest wise management of anthropogenic activities in the catchment of Oum Er Bia River and their tributaries.

Magnetic Susceptibility of Jurassic Mafic Rocks in Beni Mellal High Atlas

Mohamed El Baghdadi Ahmed Barakat Jamila Rais

The mafic intrusions in the High-Atlas of Beni Mellal occur as dykes, sills and flows which are interbedded with, or intruded into, middle Jurassic sedimentary rocks. In Idemran, they have gabbroic nature and are installed as a sill ithin Dogger limestone. Mafic dykes that crosscut Guettioua continental red series are mainly represented in Tagleft. Basaltic flows are largely widespread and overcome the greso-argillaceous formations in Naour, Sgat and Tabarouch. The sills with average thickness of 60m are intercalated into Bin-ElOuidane blue limestones. With a coarse grained texture and a green light colored rock, the sill of Idemran contains plagioclase, k-feldspar, amphibole, clinopyroxene and biotite with scarcely small olivine crystals. The Tagleft and Ichichi dolerites contain plagioclase, clinopyroxene and orthopyroxene. In addition to the latest minerals, euhedral olivine occurs predominately in gabbronorite small intrusion of Ait-Ouchen. Naour and Sgat basalts show a fluidal microlitic texture and contain plagioclase, olivine and clinopyroxene. All rocks contain magnetite, ilmenite, hematite and sulfide, but their abundances vary widely.

Petrology and Geochemistry of Ourika Gneissic Rocks (High-Atlas, Morocco): Implications for Provenance and Geotectonic Setting

Journal of environment and earth science (2013)

Ahmed Barakat Jamila Rais Mohamed El Baghdadi

Gneissic terranes under studied are one of the various formations constituting the Ourika Old massif. They underwent a metamorphic evolution characterized by a first amphibole facies event and a second greenschist facies metamorphism. The high-grade metamorphism is related to a Pan-African orogenesis that produced subduction-related granitoids preserved as GAA and GBA gneisses. These two gneissic groups have different geochemical compositions which were likely linked to the protolith nature. Petrology and geochemical investigations reveal that the protolith of GBA gneisses is calc-alkali peraluminous S-type granodiorite and thus of GAA gneisses is calc-alkali metaluminous diorite. The GBA protolith showed a continental active margin characteristic that may belong to the earlier Pan-African event, at ~780 to 750 Ma, whereas the GAA protolith could be formed in the island arc/fore-arc event, at ~753 Ma. Both groups were ordered in two lines suggesting two different sources where the crustal intervention is more or less marked, by juvenile upper continental crust for GBA protolith, and by young lower continental crust for GAA protolith. Correlated to the anti-atlasic formations of the same age, the geochemical similarities suggest a comparable geodynamic evolution that is closely linked to a Neoproterozoic continental convergent margin in the north of West-African Craton (WAC), collided at late Pan-African orogenesis. This collision induced the strongly N-S deformation that was materialized by the overthrusting of the GAA protolith onto the GBA protolith, and by the forming of the Ourika gneissic massif as a submeridian dome.

An integrated methodology for surface soil moisture estimating using remote sensing data approach

Geocarto International (2019)

Rida Khellouk Ahmed Barakat Aafaf El Jazouli Abdelghani Boudhar Hayat Lionboui

The present study aimed to propose an operational approach for estimating surface soil moisture from Moderate Resolution Imaging Spectroradiometer (MODIS) data by considering diverse environmental variables such as Normalized Difference Vegetation Index (NDVI), land surface temperature (Ts), evapotranspiration, topographic parameters (elevation and aspect) and soil texture (clay, loam and silt). A soil moisture index (SMI) derived from NDVI-Ts space is combined to all other variables, based on stepwise multiple regression, to develop a new SSMC model. Performance of this model was assessed using field-measured data of SSM. Accuracy was performed by the k-fold cross validation method, it showed a R2 (coefficients of determination) of 0.70, RMSE of 1.58% and unRMSE of 0.5%. In addition, the results of the developed model were compared with another soil moisture model SMM proposed in the irrigated perimeter of Tadla (Morocco), and revealed that the established model provided effectiveness results in the study areas.

The Karst Landscapes of Beni Mellal Atlas (Central Morocco): Identification for Promoting Geoconservation and Tourism

Quaestiones Geographicae (2022)

Abdellah Ait Barka Jamila Rais Ahmed Barakat Elhassan Louz Samir Nadem

Abstract The Atlas of Beni Mellal is located in the Moroccan central High Atlas, characterized by an important geo-diversity that attracts tourists every year. However, the number of visitors remains limited due to the lack of the promotion means, enhancement and mediation of this heritage. The obtained data indicate that the studied area preserves a great number of karst geosites, such as ruiniform landscapes, caves, poljes, sinkholes, Karren, shaft cave and many remarkable reliefs such as canyons and cliffs. This work concerns the inventory, the quantitative evaluation and the enhancement of the remarkable geomorphosites. The results reveal the presence of 21 sites, including six karst forms; five ruiniform landscapes and one karren form, one enviable panoramic viewpoint and five karst springs, four caves, two travertines, two waterfalls, and one structural relief geosite; canyon, and one tepee structures. However, these sites are not protected against all types of degradation, because the general public does not recognize them. These karst forms are very vulnerable, they cannot reproduce quickly, and their deterioration leads to their permanent disappearance. That is why this heritage must be the object of a particular attention of the whole community. The valorisation of these geomorphologic assets is the proposal of a number of circuits and geo-tourist routes from the perspective of local and integrated development.

Geological heritage of the Taguelft syncline (M'Goun Geopark): Inventory, assessment, and promotion for geotourism development (Central High Atlas, Morocco)

International Journal of Geoheritage and Parks (2022)

Elhassan Louz Jamila Rais Abdellah Ait Barka Samir Nadem Ahmed Barakat

The Taguelft syncline, located south of the Béni Mellal city, is one of the synclinal basins of the central High Atlas. It contains significant geological heritage that should be inventoried, valorized, and protected. The present study aimed to inventory and evaluate the syncline's geological heritage and then propose geotourism and geodidactic promotion allowing their sustainable geoconservation. This is done by applying the University of Lausanne methodology, based on the quantitative and qualitative assessment of the scientific (considered central) and additional values. Results highlight geodiversity elements with high scientific (≃0.84) and aesthetic (≃0.85) values related to the strong representativeness of the regional geological phenomena (genesis modes of magmatic bodied, tabular structure of Jbel Sgat, gabbroic intrusion of the Ait Boulmane wrinkle). The assessment also shows that the study area hosts a valuable palaeontological heritage enclosing fossil wood, ammonites, and dinosaur remains (bones and footprints). Moreover, it has underlined an important cultural and architectural interest of the tribe of Ait Sokhmane. Taken together, the diverse geological and cultural heritage identified can constitute a valuable tool for geoconservation and geotourism purposes. Due to their high touristic and educational potential, the geosites of the syncline are a preferred tourist destination for many visitors and can serve as valuable educational excursion sites for the dissemination of geosciences through different tools such as interpretation panels, digital media, leaflets, and guided tours. This exceptional geodiversity, and the rich cultural heritage, constitute a support for the development of geotourism and a tool for reinforcing local socio-cultural development. The knowledge and understanding of the different facets of the geological and cultural heritage as well as the management and planning of these resources all contribute to sustainable and developed tourism.

Spatiotemporal monitoring of surface soil moisture using optical remote sensing data: a case study in a semi-arid area

Journal of Spatial Science (2018)

Rida Khellouk Ahmed Barakat Abdelghani Boudhar Rachid Hadria Hayat Lionboui

Surface soil moisture content (SSMC) monitoring constitutes an important parameter to estimate crop water requirements, especially in arid and semi-arid areas. Remote sensing became a useful tool for estimating SSMC. Two approaches were applied for monitoring the SSMC during the 2013/14 cropping season in the irrigated perimeter of Tadla (Morocco) using multispectral bands of Landsat-8 OLI images. The first approach examined the potential of visible and short-wave infrared drought index (VSDI), normalized multi-band drought index (NMDI) and short-wave infrared water stress index (SIWSI), to retrieve SSMC. The second approach attempted to develop a new SSMC model based on evaluation of the correlations between multispectral bands and measured SSMC using a stepwise multiple regression analysis. Results showed that the established model is highly correlated with the measured SSMC at all crop growth stages with R2 of 0.87, 0.85 and 0.89, for bare soil, partially covered and entirely covered by vegetation, respectively.
