Geochemical dataset of laterites soils in Koubou gold district (Zone A) East Cameroon: Implication for identification of gold pathfinder elements.

The study zone (A) located in the Koubou Gold district is situated between latitudes 4° 36' to 4° 42' N and longitudes 14° 08' to 14° 11' E, composing of mostly Gneiss and Granodiorite bed rocks. To determine the relationship between gold and selected pathfinder elements (As, Mo, Ag, Sn, Sb, Te, W, Bi, Ni, Cu, Sb, Nb, Ta, Fe, Mn, Cu, Zn, Ni, and Pb) in the laterite soils of the Koubou gold district, East region of Cameroon, a lithogeochemical dataset from the laterites were utilized. The lithogeochemical dataset were realized through the inductively coupled plasma mass spectrometry (ICP-MS) method, while multi-statistical methods of factor analyses, principal component analyses and hierarchical clustering employed to show the relationship between the gold mineral and selected pathfinder minerals.

Lithotectonic setting, paleoweathering, maturity, sediment recycling and paleoredox conditions of quaternary alluvium from Mayo Sina (Tchad). A geochemical approach.

The alluvial material in the two PITs of the Mayo Sina in the southern part of Chad, were subjected to a geochemical analysis in order to determine the source rock lithological composition, tectonic context, degree of weathering, type of climate at the period of weathering, and cycles of sedimentation and maturity. Plotting source lithology charts with values of La/Sc, Th/Sc, La/Co, and Cr/Th indicated that the sediments originated from a felsic source rock composition. The Enrichment of LREE/HREE and a negative chondrite Eu anomaly confirm the felsic source rock composition.

Geochemical balance of the mineral fraction and statistical analyzes of the Ebolowa municipal lake's sediments (central Africa): Implication for early diagenesis process.

The Ebolowa Municipal Lake (EML) (South Cameroon) in order to identify the early diagenesis processes taking place in the lake and the factors influencing them. To this end, 21 samples were collected. In situ, hydrogen potential, redox potential, conductivity, dissolved oxygen content, and turbidity were measured.

Geochemical characterisation of clastic sediments in Kompina (N'kapa Formation, NW Douala Basin, West Cameroon): Implication for provenance, paleoweathering and sediment maturity.

Chemical analyses were carried out on clastic sedimentary rocks in Kompina (N'kapa Formation of the NW, Douala Basin, West Africa) to disclosed the composition of their source rock, characterised their tectonic domains, decipher the intensity of the past weathering, sedimentary cycles and maturity using concentrations of major oxides, REES and trace elements. Provenance diagram constructed from ratios of La/Co, La/Sc, Th/Sc, Cr/Th and from binary diagrams of Zr vs TiO and ALO TiO, disclosed a felsic rock composition as the source rock of the Kompina clastic rocks. The felsic source rock composition designated for the studied clastic materials is also supported by LREE enrichment over HREE and a negative europium anomaly on chondrite calculation and diagram.
