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(...)

Petrographic and Geochemical Characters of Granites of the Banfora Belt, Burkina Faso (West Africa)
Abdoulaye Ouedraogo, Seta Naba, Hermann Ilboudo
The Banfora’s birimian greenstones belt is located in the western part of Burkina Faso (west Africa). Recent petrographic and lithogeochemical studies have highlighted plutons intruding the metasedimentary and metavolcanic series. These plutonic rocks are composed of leucogranites belonging to the so called Ferkessedougou’s or Ferke’s batholit(...)

Structural Pattern Related to Gold Mineralization in the Essakane Area (Northern Burkina Faso, West African Craton)
Marc Desire Valea, Benjamin Sawadogo, Kalidou Traoré, Urbain Wenmenga, Naba Seta, Benjamin Allou
The finite deformation structures recorded in the Essakane area, located in the northeast corner of Burkina Faso, highlight three major compressive deformation phases, successively named D1, D2, and D3. The D1 event phase, trending NESW, is characterised by P1 folds and S1 axial plane schistosity. The D2 phase trending NW-SE is characterised b(...)

Effects of Organic Compost and Trichoderma harzianum Spores on Soil Fertility and Agronomic Performance of Soybean (Glycine max (L.) Merr.)
Koulibi Fidèle, Kounbo Dabiré, Sibiry Albert Kaboré, Moussa Tondé, Daouda Guébré, Abdramane Sanon, and Edmond Hien.
The food supply has grown steadily over the years, while production has been hampered by the increased use of synthetic fertilizers, leading to pollution and degradation of soil physico-chemical properties. It is imperative to advocate for the promotion of sustainable farming techniques that can enhance crop yields while improving soil fertili(...)

Integrating geospatial data and multi‑criteria analysis for mapping and evaluating the mineralization potential of the Dschang pluton (Western Cameroon)
Fozing Eric Martial, Tcheumenak Kouémo Jules, Sawadogo Sâga, Chako Tchamabé Boris, Ousmanou Safianou, Foka Koagne Staelle, Nguimezap Marie Madeleine, Kwékam, Maurice
The Dschang area has substantial mineral and geological exploration potentialities. However, its basement is unclear due to lack of studies on mineral and lithology mapping, and other mineralization indices. The lithological units and potential hydrothermal alteration zones in the Dschang area are investigated here using remote sensing; geogra(...)

Geographical distribution of enteric pathogenic viruses in Burkina Faso: a systematic review and meta-analysis
TRAORE Kuan Abdoulaye, AKAPOVI M. Marius, OUEDRAOGO Nafissatou, OUOBOA Jen Bienvenu, ROQUES Pierre and BARRO Nicolas
Background
Viruses, which are transmitted mainly via the digestive tract, are responsible for the high morbidity
and mortality of diseases, particularly in low-income countries. Although several studies have established the prevalence and characterization of various enteric viruses in Burkina Faso, to date, no aggregate data have been rele(...)

Geology and metal anomalies of the Kampti-Loropeni greenstone, Burkina Faso (West African Craton)
Mathieu Nanema , Hermann Ilboudo, Justin Winhyel Some , Ignace Dabone
Stream sediment geochemistry is a method of regional exploration to screen wide areas, of difficult access or high rainfall marked by significant forestry development. This method, combined with remote sensing, petrographic, analytical studies and field work, has enabled us to highlight areas of metal anomalies in the Kampti-Loropeni greenston(...)

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

Geochemical feature of the Mangodara metavolcanic rocks within the Banfora Paleoproterozoic greenstone belts, southern Burkina Faso (West African Craton)
Bernadin Gnamou, Hermann Ilboudo, Wilfried Antoine Bassou Toe, Sâga Sawadogo
We present new geochemical data on the volcanic rocks of the Mangodara sector (southeastern edge of the Banfora Paleoproterozoic belt) in the West African Craton and discuss their petrology and geodynamic context. Three main volcanic units are described, notably andesites, dacites, and rhyolites. These lithologies are dominated by volcanoclast(...)

Caractères pétrographiques et géochimiques des granitoïdes Paléoprotérozoïques de Godé au Nord du degré carré de Léo, Centre-Ouest du Burkina Faso (Afrique de l’Ouest)
Adama Ouédraogo Yaméogo, Hubert Gounwendmanaghré Zongo, Pascal Ouiya, Omar Akonyiré , Abraham Seydoux Traoré , Saga Sawadogo, Séta Naba
Dans le domaine Baoulé-Mossi de la dorsale de Man/Léo, les granitoïdes sont d’âge Paléoprotérozoïque et constituent des volumes importants de roches qui recoupent les ceintures de roches vertes. Ainsi, les granitoïdes sont de bons marqueurs de la déformation crustale et leur étude contribue à élucider les processus géodynamiques qui s(...)

Sorghum and cowpea intercropping response to woody residue amendments in Sahelian agro-ecosystems of Burkina Faso
Daouda Guébré, Salifou Traoré, Koulibi Fidèle Zongo, Edmond Hien
In West African agro-ecosystems, soils are inherently low in soil organic carbon decreasing the capacity of soils to sustain crop productivity. Woody Residues instead of being burnt or exported out of the cropping systems, can be managed to optimize soil organic carbon build-up, nutrient cycling and crop productivity. The aim of this study was(...)

Influence of agroforestry systems on earthworm diversity and soil properties in a Sudano-Sahelian landscape
Adama Zoungrana , Mohamed Cissé, Mamoudou Traoré, Charles De Cannière , Babou André Bationo , Marjolein Visser, Salifou Traoré
Agroforestry systems promote a range of ecological base management to support sustainable agriculture. However, the influence of agroforestry management on soil biodiversity is still poorly investigated in SudanoSahelian landscapes. This study aims to guide sustainable management for soil biodiversity conservation in agroforestry systems by(...)
