M. Ouangrawa et al., Evolution of gold particles in a lateritic Sudano-Sahelian area: alluviumsand colluviums of the Piela deposit, Burkina Paso, B SOC GEOL, 171(4), 2000, pp. 397-405
On a barren bedrock, transported auriferous materials of colluvial and allu
vial origin present differences in the distribution, composition and morpho
logy of gold particles, Under Sudano-Sahelian conditions, transport process
es shape evolved particles in short distances.
