Abstract: Located in the central part of North China Craton, Wutai area is an important area of gold mineralization in Shanxi Prov-ince; nevertheless, complex geological settings of this area lead to rare recent prospecting breakthroughs. In mineral prediction, the geological evidence weight approach can rapidly screen geological variables to calculate weights and anomaly index and extract local weak geological anomalies, whereas the gray theory approach can delineate prospecting targets by using only a small amount of infor-mation. These methods can be jointly utilized to look for a breakthrough. In delineating the prognostic target areas based on verified known deposits, four primary targets and a secondary target in Wutai area were delineated. This Weight-Anomaly-Gray Theory conjoint analysis is believed to be an important application in mineral prediction with unique application effect.
