Micro-XRF-Based Quantitative Mineralogy of the Beauvoir Li Granite: A Tool for Facies Characterization and Ore Processing Optimization
Zia Steven Kahou , Michel Cathelineau], Wilédio Marc-Emile Bonzi , Lise Salsi,Patrick Fullenwarth
Quantitative mineralogy plays a vital role in exploration geology by defining mineral assemblages, identifying metal-bearing phases, and providing clues to optimize ore processing. In peraluminous rare-metal granites such as those at Beauvoir (France), mineral quantification is challenging, especially in altered facies where partial replacemen(...)

Contamination status and toxicity risk assessment of selected potentially toxic elements in surface soils under the influence of different land uses in Midwestern Burkina Faso, West Africa
Michel Bembamba et Aboubakar Sako
Background: As land use transitions from rain-fed farming to market gardening and artisanal gold mining in
Burkina Faso, soil contamination with potentially toxic elements (PTEs) has become a major environmental
concern.
Objective: This study investigates the PTE pollution status of highly anthropized soil in Midwestern Burkina Faso.

Geochemical characterization of potentially toxic elements in topsoil under different land‑use patterns in the village of Guido (Midwestern Burkina Faso) using multivariate geostatistical techniques
Michel Bembamba and Aboubakar Sako
Burkina Faso faces a major challenge of environmental degradation due to a booming of gold mining. To date, there is no available information regarding soil geochemical status of this rapidly transitioning land use from merely subsistence agriculture to market gardening and artisanal gold mining. Therefore, this case study investigates distrib(...)

Hydrochemical assessment of groundwater quality from fractured basement aquifers in the South-central of Burkina Faso, West Africa
Césard Millogo, Aboubakar Sako, Blehiman Sagnon, Samuel Nakolendoussé
In central southern Burkina Faso, as elsewhere in the country, groundwater resources are the reliable source of drinking water. During its residence time in the rocks, the groundwater interacts with them and its chemical composition is considerably modified. Methods like major ions geochemistry, the assessment of water quality indices, and the(...)

Geochemical Modeling and Quality Assessment of the Surface Waters from the Mouhoun River System, Burkina Faso: Implications of Water–Rock Interactions and Anthropogenic Activities
Pélagie Wend Bénedo Korsaga, Aboubakar Sako and Césard Millogo
Major ion and heavy metal geochemistry was used to investigate the factors that control the Mouhoun River water quality in western Burkina Faso. Major cation concentrations was in the following decreasing order: Ca2+> Na+> K+> Mg2+, reflecting silicate weathering. However, relatively high HCO3- and SO42- concentrations could be related to diss(...)

Hydrogeochemical Characterization and Multivariate Analysis of Groundwater in Pala, Burkina Faso: Implications for Sustainable Water Management
Césard Millogo, Corneille Bakouan, Aboubakar Sako and Samuel Nakolendoussé
The quality of groundwater and spring water in the Pala locality, influenced by both natural processes and human activities, is a major issue in the supply of drinking water to the city of Bobo Dioulasso. The geological context is mainly composed of Sotouba sandstone. This influences the chemical composition of the aquifers through water-rock(...)

Comprehensive assessment of heavy metal pollution of agricultural soils impacted by the Kalsaka abandoned gold mine and artisanal gold mining in northern Burkina Faso
Baonipouo Anselme Metoman Dabiré and Aboubakar Sako
In this study, the environmental quality of agricultural soils around the Kalsaka abandoned gold mine was evaluated. A total of 117 samples including industrial mine wastes, topsoil, and control soil were collected in and around the mine, and their heavy metal concentrations were determined using ICP-MS after aqua regia digestion. Except for Z(...)

Cartographie du massif bauxitique de Foulou par photo-interprétation en 3D (Centre-Nord du Burkina Faso)
Benjamin SAWADOGO, Wilédio Marc-Emile BONZI, Kalidou TRAORE
Dans cette étude, nous proposons une méthode de cartographie géologique et minière basée sur la photo-interprétation en 3D avec des images satellitaires de haute résolution spatiale. Cette méthode se révèle être une approche résiliente pour la cartographie dans les pays sahéliens où les observations de terrain sont limitées à cause de l'insécu(...)

Hydrothermal Alteration Associated with the Kiaka World-Class Gold Deposit (Burkina Faso, West Africa)
Benjamin Sawadogo, Gounwendmanaghré Hubert Zongo, Wilédio Marc-Emile Bonzi, Kalidou Traore, Sâga Sawadogo, Ousseni Yameogo, Ousmane Bamba, Guy Franceschi
This paper aims to show the relationships between hydrothermal alteration, deformation and gold mineralization in the main area of the Kiaka deposit. The Kiaka gold deposit is located in the South-central of Burkina Faso in the Tenkodogo volcano-sedimentary belt. Mineralization is primarily hosted by amphibolite, mylonitized quartz microdiorit(...)

Geostatistical modelling of physico-chemical properties of soils impacted by artisanal gold mining and farming: implications for soil environmental quality assessment
Kadidiatou Coulibaly & Aboubakar Sako
In this study, geostatistical techniques were used to investigate spatial variability of physicochemical properties of soil samples from farming- and artisanal gold mining-affected areas. Based on coefficients of variation, chemical properties, except pH, had high variability compared to physical properties. This could be attributed to the loc(...)

Environmental Geochemistry and Human Health Risk Assessment of Potentially Toxic Elements in Urban Soils in the Vicinity of a Pb Fire‑Assay Laboratory in Ouagadougou, Burkina Faso
Kadidiatou Coulibaly & Aboubakar Sako
A total of 30 topsoil, subsoil samples, and 11 new and used cupels were collected around a Pb fusion fire-assay laboratory in Ouagadougou, Burkina Faso, and their physico-chemical parameters and major and potentially toxic (PTE) element concentrations were determined. The results showed that the soil samples in the immediate vicinity of the us(...)

Hydrogeochemical characterization and natural background level determination of selected inorganic substances in groundwater from a semi‑confined aquifer in Midwestern Burkina Faso, West Africa
Aboubakar Sako and Cheik Abba Cissé Ouangaré
Hydrogeochemical processes that govern selected inorganic substances distribution in a
semi-confined aquifer were characterized using traditional hydrogeochemical approaches and natural background levels (NBLs). Saturation indices and bivariate plots were used to investigate the effects of water–rock interactions on natural evolution of the g(...)

Wilédio Marc-Emile Bonzi, Marieke Van Lichtervelde, Olivier Vanderhaeghe, Anne-Sylvie André-Mayer, Stefano Salvi & Urbain Wenmenga
The Mangodara district (southwestern of Burkina Faso, West African Craton) consists of a regional-scale Eburnean dome cored by granitoid-gneisses comprising rafts of migmatitic paragneisses and amphibolites of the Paleoproterozoic Birimian series. The occurrence of rare metal-bearing pegmatites in diffuse contact with these migmatitic and gran(...)

We describe the geological context of rare metal-bearing pegmatites from the Mangodara district (South-West Burkina Faso, Paleoproterozoic West African Craton) and discuss their petrogenesis and links with the host rocks. The Mangodara district exposes a gneiss-granitoid complex structured in a regional-scale dome, mantled by granodioritic gne(...)
