Geochemical, lineament and lithology data were the selected recognition criteria. The mentioned criteria varied against 75 known hydrothermal occurrences; the geochemical data had a weight of (W^+= 1. 209 7, W^- =-0. 748 1) being the maximum among the three and the rest lineament and lithology have (W^+= 0.7424, W^-= -0.449 6), (W^+= 0.378 7,W^-=-0.6243) respectively. The application was successful since the predicted results covers about 70% of the known deposits and predicted unknown areas.展开更多
文摘This paper discusses the application of the model in predicting for hydrothermal Cu, Ag, Au and Pb-Zn occurrences in northwestern Yunnan. Geochemical, lineament and lithology data were the selected recognition criteria. The mentioned criteria varied against 75 known hydrothermal occurrences; the geochemical data had a weight of (W^+= 1. 209 7, W^- =-0. 748 1) being the maximum among the three and the rest lineament and lithology have (W^+= 0.7424, W^-= -0.449 6), (W^+= 0.378 7,W^-=-0.6243) respectively. The application was successful since the predicted results covers about 70% of the known deposits and predicted unknown areas.
