Differentiation of Sahelian aquifers from chemical and isotopic composition using linear statistics and machine learning
Abdoul-Azize Barry, Suzanne Yameogo, Meryem Touzani, Samuel Nakolendoussé, Meryem Jabrane, Abdessamad Touiouine, Ismail Mohsine, Laurent Barbiero & Vincent Valles
In Sahelian Africa, the characteristics of boreholes are often lost and, when several aquifers are present on
the same site, it is difficult to know which one is being tapped or is likely to be contaminated, which
hinders good management of the resource. In this study conducted on 153 wells distributed in the four
major aquifers of Burki(...)

Alteration Typology and Geochemical Signatures of the Napélépéra Gold-Bearing Granodiorite in South-West Burkina Faso (West Africa) Alteration Typology and Geochemical Signatures of the Napélépéra Gold-Bearing Granodiorite in South-West Burkina Faso (West Africa)
OUEDRAOGO Théophile, SAWADOGO Sâga, ILBOUDO Hermann, NABA Séta
The characterization of the relationships between mineralization and hydrothermal alteration is an essential element in understanding gold deposits. In south-west Burkina Faso, the Napélépéra mineralisation, the mobility of chemical elements and alteration-mineralization relationships were studied by means of selected core drilling and geochem(...)

Geochemical Mobility Associated to Gold and Base Metal Occurrences of Mangodara Sector, in Southern Burkina Faso, Banfora Greenstone Belts (West African Craton)
Bernadin Gnamou, Hermann Ilboudo, Wilfried Antoine Bassou Toé, Sâga Sawadogo
In the Mangodara area within the Banfora greenstone belts (Baoulé-Mossi domain of the West African Craton), our study focused on geochemical assessment of the mobility of major and trace elements. Gold and base metal occurrences are hosted in highly metamorphic felsic (metarhyolite) and intermediate (metadacite and metaandesite) formations. Co(...)

The reconstitution of the geodynamic processes of the Eburnean orogeny in the time span around 2.1 Ga in Dori area is here carried out through the examination of the internal structures and microstructures of the Dori, Gorom-Gorom and Touka Bayèl granitic plutons. The radiometric ages of these plutons vary between 2164 Ma and 2148 Ma. The inte(...)

Sorghum and cowpea productivity as influenced by tillage, cropping system with soil amendment in Centre-West Region of Burkina Faso
KOUMBEM Mahamoudou, PALE Siébou, HIEN Edmond, YONLI Djibril, TRAORE Hamidou, PALE Grégoire, PRASAD Vara PV Middendorf 3
Improving crop productivity requires integrated management of soil fertility. This study aimed to assess the effects of tillage and the cropping system with soil amendment on the productivity of sorghum and cowpea. The experimental design was a completely randomized block with the treatments arranged in a split plot and three repetitions. Four(...)

Disk Galaxies Are Self-similar: The Universality of the HI- to-Halo Mass Ratio for Isolated Disks
Marie Korsaga, Benoit Famaey, Jonathan Freundlich, Lorenzo Posti, Rodrigo Ibata, Christian Boily, Katarina Kraljic, E. Esparza-Arredondo, C. Ramos Almeida, Jean Koulidiati
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter. Here, we study the scaling relation between the neutral hydrogen (HI) and dark matter mass in isolated rotationally supported disk galaxies at low redshift. We first(...)

The 17O-excess, d-excess and d18O composition of precipitation in Northern Benin
Christine Vallet-Coulomb, Christophe Peugeot, Anne Alexandre, Diego Chavez-Espinoza, Claudia Voigt, David Au-Yang , Théodore Ouani , Simon Afouda , Maxime Wubda
The intraseasonal and interannual variability of the West African monsoon greatly
impacts water resource security and flood risks in the intertropical regions of Africa. The stable
isotope composition of precipitation may help to understand and monitor the processes
controlling the monsoon cycle. It is controlled by the different steps of t(...)

Impacts of climate change and pumping on groundwater resources in the Kou River basin, Burkina Faso
Justine Tirogo, Anne Jost, Angelbert Biaou, Youssouf Koussoubé, PierreRibstein and Denis Dakouré
West Africa is subject to climatic variability with a long period of drought during the 1970s–1990s whose impact on groundwater remains poorly studied. This work focuses on the Kou basinin Burkina Faso, which holds a large groundwater resource resulting in exceptional springs. Thisresource shows signs of depletion that raise a critical questio(...)

Bambara groundnut (Vigna subterranea [L.] Verdc.) is a seed legume native to West Africa with significant
agronomic, nutritional, economic and socio-cultural potential. In Burkina Faso, its cropping faces enormous
constraints from poor soil fertility and poor nutrient management practices. This study aimed to evaluate the
effects of differe(...)

The salinity of estuarine areas in arid or semi-arid environments can reach high values, conditioning the distribution of vegetation and soil surface characteristics. While many studies focused on the prediction of soil salinity as a function of numerous parameters, few attempted to explain the role of salinity and its distribution within the(...)
