Mining Implication in the Geochemical Exploration of Fluvial Sediments of the East Nyambaka Volcanic Zone (Adamawa-Cameroon)

Geochemical characterization in stream sediments from Nyambaka locality was carried out on ten samples collected the study area watershed. The distribution of trace metals showed that some lithophiles (Be, Sc, V, Cr, Sr, Th, U), chalcophiles (Cu, Zn, Ga, As) and siderophiles (Mn, Co, Ni, Mo) have high average contents compared to their concentration upper crust. From factorial analysis components, total variance explained made it possible represent capture main information data them a graphical frame. Thus, using this frame, elements were divided into four groups opposed each other. They show an enrichment group 1 (Cr, Cu, Mn, Be, Zr, Ba, Mg) 2 (Mo, As, Hg, Ag) more than 3 (Ga, U) 4 (Au, Th). Rare earth indicates abundance Lanthanide (28.1 ppm 42.4 ppm), light rare (LREE), depletion heavy (HREE). variable LREE/HREE (7.24 LREE/ HREE 12.22) (La/Yb)N (6.70 11.72) ratios suggest effect heterogeneous sorting minerals with dense resistant minerals.
