通过对寨上—马坞地区地质资料的分析，在综合研究地层、岩浆岩和构造等地质条件的基础上，运用证据权重法对岷县寨上—马坞地区开展了成矿预测，圈定成矿远景区12个，其中，Ⅰ级成矿远景区4个，Ⅱ级成矿远景区3个，Ⅲ级成矿远景区5个。经过综合评价，得出该地区找矿效果良好，并提出下一步找矿方向：①教厂坝岩体东北侧找金；②已知金矿深部富金脉型及斑岩型金矿的探索；③已知地表规模较大、金含量较低或显示低温元素组合的破碎蚀变带深部的地质找矿综合评价；④第三系和第四系厚覆盖区下方隐伏和半隐伏金矿的勘查评价。

Through analyzing the geological material about Zhaishang-Mawu region combined with comprehen-sive research on strata,magmatic rocks and tectonic geological conditions,weights of evidence method was employed for metallogenic prediction in the study area.There were 12 metallogenic prospects,namely fourⅠlevel metallogenic prospects,three Ⅱ level metallogenic prospects and five Ⅲ level metallogenic prospects.Through the comprehensive evaluation,it can be concluded that the regional prospecting effect was good,and we have put forward the next step regarding prospecting direction:①Search for gold ore in northeast of Jiaochang rock mass;②Known deep invited vein type gold deposit and porphyry gold deposit exploration; ③Known surface large,gold content was low temperature element combination of broken alteration zone of deep geological prospecting comprehensive evaluation;④Made exploration evaluation on the concealed and half concealed gold deposit below the tertiary and quaternary thick covering area.
