Abstract: With summarization and study of the ore-forming geological conditions of the Hg-Pb-Zn deposits in FenghuangMayang area, the forecasting types of deposit in the area are determined to establish the forecasting elements for a regional forecast model. According to the forecasting criteria and grading principle, with the regional metallogenic belt division and the characteristics of ore-forming series, 12 prospective areas are forecasted. By computer optimization with manual intervention, 19 exploration targets are delineated finally.
