%X Bolong porphyry Cu-Au deposit, neighbouring Duobuza porphyry Cu-Au deposit, is a newly discovered deposit. Two stages of granodiorite porphyries were emplaced in Bolong deposit, and followed by later intruding granite porphyry. Phyllic alteration is occurring on the surface of Bolong deposit, and potassic alteration was found in the depth associating with granodiorite porphyries. At Bolong, Re-Os data of four molybdenite samples from quartz-molybednite veinlets yielded an isochron age at 119.4±1.3Ma (MSWD=0.63, n=4), coincident to the mineralization age of Duobuza deposit. Similar mineralization age, closely neighbouring spatial distribution of Bolong and Duobuza porphyry deposits suggest that these two deposits might be generated from a same tectonic-magmatic activity background, and some potential large porphyry copper deposits could be occurred in Duolong metallogenic district.
