Study of the Behavior of Gold and Accompanying Chemical Elements in Weathering Profile on a Quartz Vein in Mintom (South Cameroon, Central Africa)

The present study, which focuses on the behavior of gold and its accompanying chemical elements developed an alteration profile, is carried out in a humid equatorial zone at Mintom South Cameroon (Central Africa). methodology used to achieve results obtained focused description morphology outcrop, petrography rock studied, study heavy minerals weathering materials smear slides, mineralogical analysis by X-ray diffraction (XRD), scanning electron microscopy (SEM) geochemical analyzes ICP - AES MS materials. main from this inform us that petrographic level studied gold-bearing quartz vein located Zom, consisting mainly opaque minerals. Morphologically, granite basement advanced ABC-type profile characterized significant thickness (4 6 m). morphological characters particles have evolved mineralized surface. This development was marked increase blunt, rounded grains. Morphoscopy shown hollow, blunt sub-blunt grains, non-evolved free particles, respectively. In most samples weathered material found association with such as Ag, Cr, Co, Cu, Ni, V figure 10 show identical between these gold, but particularly silver would testify origin. Au concentrations are very high material. Also, altered proportion (0.01 2.28 ppm) also (Ag) justifies occurrence or deposit associated can be exploited parameter prospect for area.
