Abstract: Jinchang Gold Deposit is a super large-scale rock gold deposit,incorporating in itself explosive breccia pipe type,fine-vein disseminated type and alteration rock type mineralization.Daughter-mineral bearing multiphase fluid inclusions(number of daughter minerals≥4) widely develop in ores from all 3 types mineralization.In addition to salt daughter minerals(NaCl),opaque daughter minerals often can be observed.Scanning electron microscopy study shows that they are mainly such sulfide daughter minerals as pyrite,chalcopyrite and sphalerite.These sulfide daughter minerals are is consistent with the mineral assemblage observed in ores from all 3 types mineralization.This gives direct evidence that the ore-forming materials mainly came from magmatic intrusions.
