| Abstract: | The potential pathfinder elements iodine, as total (Itot) and watersoluble (Iaq), chlorine (Cltot and Claq) together with F, As, Pb, Zn and Cu have been determined in B horizon soils over proved lead-zinc mineralisation east of the disused Glogfawr mine, Dyfed, Wales. Pb and Cu are anomalous in soils over this occurrence while Zn fails to reflect underlying mineralisation. Total and water soluble I and Cl show anomalously high values over the proved mineralisation and also indicate extensions along the trend of the mineralised fracture system to the south-southwest and the north-northeast; these anomalies are more extensive than those formed by Pb or Cu.In the soils analysed there is a strong correlation between Itot and Iaq and Cltot and Claq and it is possible that a simple water-extractable method could be of use in geochemical prospecting. |
