One water sample per 2 km×2 km was taken along marginal faults of Linglong Complex. pH, conductivity and sulfate were measured in the field. IGGE did an analysis of indicator elements. High Au, high sulfate, low pH, high Cu, Pb, Bi, Sb, Cd, and locally high As are indicators of gold mineralization. There exists a very good hydrogechmical anomaly composed of sulfate, pH, Cu, Cd, Sb, Zn, Bi in the Linglong-Taishang orefield. In addition to the Beibo-Xidian orefield and the Dayingezhuang-Caojiawa orefield, a few new potential prospective targets were delineated. (Well) water geochemical survey can be a useful method for gold exploration in Jiaodong Peninsula. Hydrogeochemical survey is hopefully applied to delineating orefield or ore deposit targets in Quaternary cover and/or exposed areas with dense population.
