摘　　要：用质子微探针设备研究了500μm×500μm区域内的金驹山金银矿和金牙微细粒金矿样品。结果表明,前者Au与Ag具有正相关关系,Au与Fe在微区范围内具有反相关关系;后者矿中Au与As、S、Fe,特别是与As具有密切的相关关系。A proton microbeam with 2μm lateral resolution has been established at the Accelerator Laboratory of Fudan University and was used to study gold-bearing submicroscopic gold minerals and gold inclusions. Au is found to be closely related to Fe,S,and especially to As in the mineral sample from Jinya, Guangxi province.
