Due to the limited reach of the drinking-water delivery network, Yaoundé’s surrounding communities (such as Nkoabang) rely on well water, boreholes, and springs. This study conducted a Thornthwaite water-balance analysis in the watershed in order

Mineralogical, geochemical, and geotechnical features of lateritic soils from termite mounds in two contrasting savannah areas (central Cameroon) as raw materials for brick making

Autor: Jean-Marc Kessoum Adamou, Roger Firmin Donald Ntouala, Estelle Ndome Effoudou, Marie Thérèse Nanga Bineli, Arnaud Ngo'o Ze, Gouban Hamadjida, Vincent Laurent Onana

Publikováno v: Heliyon, Vol 9, Iss 6, Pp e17257- (2023)

Termite mound soils (TMS) from humid savannah (HS) and dry savannah (DS) were evaluated as raw materials for compressed earth bricks (CEB) and fired bricks. Mineralogy and major elements geochemistry were performed by X-Ray Diffraction and X-Ray Fluo

Major, trace and REE geochemistry in contrasted chlorite schist weathering profiles from southern Cameroon: Influence of the Nyong and Dja Rivers water table fluctuations in geochemical evolution processes

Autor: Estelle Ndome Effoudou, Georges Emmanuel Ekodeck, Vincent Laurent Onana, Roger Firmin Donald Ntouala, Veronique Kabeyene Kamgang, Sylvie Noa Tang

Publikováno v: Journal of African Earth Sciences. 124:371-382

Three weathering profiles developed on chlorite schists, formations on which little studies have been conducted, were chosen to understand the weathering processes prevailing downslope in Southern Cameroon. The materials nearest to Nyong River at Ayo

Relationships between major and trace elements during weathering processes in a sedimentary context: Implications for the nature of source rocks in Douala, Littoral Cameroon

Autor: Likiby Boubakar, Estelle Ndome Effoudou-Priso, Véronique Kamgang Kabeyene Beyala, Georges Emmanuel Ekodeck, Vincent Laurent Onana

Publikováno v: Geochemistry. 74:765-781

In Douala (Littoral Cameroon), the Cretaceous to Quaternary formation composed of marine to continental sediments are covered by ferrallitic soils. These sediments and soils have high contents of SiO 2 (≥70.0 wt%), intermediate contents of Al 2 O 3

Behaviour of REE and mass balance calculations in a lateritic profile over chlorite schists in South Cameroon

Autor: Vincent Laurent Onana, Véronique Kamgang Kabeyene Beyala, Estelle Ndome Effoudou Priso, Georges Emmanuel Ekodeck, Jean-Claude Parisot

Publikováno v: Geochemistry. 69:61-73

An in situ weathering profile overlying chlorite schists in the Mbalmayo–Bengbis formations (South Cameroon) was chosen for the study of the behaviour of REE and the evaluation of geochemical mass balance. After physical and mineralogical studies,
