Abstract: East Kunlun metallogenic belt has mainly undergone four developing period or tectonic cycles: Proterozoic,Early Paleozoic,Late Paleozoic and Mesozoic.Mesozoic tectono-.magmatic-metallogenic activity plays an important role on regional copper-gold polymetalIic large.-scale metallogeny.Based on the ore-controlling of regional abyssal fault as the main line,it has researched East Kunlun tectono-magmaticmineralization in Qinghai and main minerals distribution characteristics,discussed the regional metallogenic regularity and the formation conditions of large-superlarge mineral deposits,and suggested exploration ideas and prospecting orientations of the magmatic hydrothermal type copper-gold polymetallic deposit.
