Abstract:

Through analyzing the geological material about Zhaishang-Mawu region combined with comprehensive 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.

Key words: weight of evidence method, metallgenic prediction, prospecting effect, Zhaishang-Mawu area, West Qinling
