The gold exists mostly in supergenic media including underground water, surface water, and stream sediments by six facies, such as soluble facies, surface adsorbing facies, organic facies, natural gold facies, iron and manganese oxides facies, and sulfide facies. The gold displays more siderophility, but has sulphophility under supergenic environment. In fact, on the basis of understanding the law of gold supergenic transportation and enrichment, it can reach good anomaly evaluating exploration effect by using anomaly proving →elements facies analyzing →anomaly judgement and ordering → checking and estimating→validating work procedure during concretely evaluating gold supergenic anomaly, and illustrate by case in Huangjiawan region.
