After analysing the significance of eight indictor models,three applied models of predication were established, 1 ) the applied model of predication for orefield, 2 ) the applied model of predication for alterration mineralization and placer predication, 3 ) the applied modelof predication for blind ore bidies.Using the three models, the authors proposed six first-grade predicated districts of blind gold deposit; three second-grade predicated districts; and two placer predicted districts. The ideal effect of predication was proved.
