Abstract: Shaxi Porphyry copper deposit, located in the central Anhui Province, eastern China, is one of the important discoveries in the middle—lower Yantse reaches in mid-1980s’. Gold mineralization also widely exists in the deposit. However, the occurrence of gold is not fully investigated and remains unknown at present. In this paper-gold occurrence has been studied by application of proton and nuclear microprobes in PIXE system. It shows that the gold in the porphyry copper deposit mainly occurs as micro-grained native gold with μm grade, and the host minerals of gold an mainly pyrite and chalcopyrite. The results provide the theoretical evidence for the synthetical utilization of gold in porphyry copper deposits and a new method for the study of gold occurrence in other similar ore deposits.
