摘要
This paper combines entropy and gray correlation degrees to study the relationship between geological variables and ore units to locate ore targets. Based on the theories and methods of metallogenic prognosis by using synthetic information, the study area (in Altay, Xinjiang) is divided to 16 gold deposit concentrated areas and 14 gold anomaly-concentrated areas. The results show that gravitational gradient, aeromagnetic, and catchment are effective indicators to look for gold mines and unit number 6, 22, 18, 19 and so on contain a large gold deposit, respectively, which was confirmed by other means. It shows that the method can be effectively applied to delineate and assess ore-finding targets.
