Geochemistry, mineralogy, and isotope composition of Pb, Zn, and Cu in primary ores, gossan and barren ferruginous crust from the Perkoa base metal deposit, Burkina Faso

Original language description

Gossan at the Perkoa deposit of stratabound lead and zinc ores (Burkina Faso) is composed of hematite, goethite, clay minerals, minerals of the brucite group and sulfates (corkite, alunite, natroalunite, hinsdalite and hidalgonite). Compared with the barren ferruginous crust in the same area, the gossan is significantly enriched in most of chemical elements, namely As, Pb, Sb, and Zn and to lesser extent also in Ag, Ba, Cd, Mo, S, and Sr. The isotopic composition of lead in massive primary ore and in gossan is practically identical. However, the isotopic composition of lead in disseminated ores, the bleached gossan envelope, and in mineralized soils in the Perkoa area is very variable and reflects mixing of ore and lithogenic lead. The chemical weathering of sulfide-rich rocks thus gives rise to considerable variations in Cu isotopes and minor changes in Zn isotopes. Isotopic composition of copper in gossan differs from barren laterite duricrust which is more depleted in the Cu-65 isotope.
