摘　　要：本文对西藏贡觉县各贡弄铜金矿区铜金矿产出地质特征进行介绍,并对其与地球物理、地球化学的关系予以阐述,指出该矿区与西藏玉龙斑岩铜钼矿同处一带上,典型面状蚀变特征明显,富集的Au、Ag、Cu、Pb等亲Cu元素来自大小不等的斑岩岩株,显示本区有进一步寻找斑岩型铜金矿的潜力。This paper introduced geological features of this copper-gold ore deposit occurring in the Gegongnong copper- gold ore district, Gongjue County, Tibet, discussed its relationship with geophysical and geochemical signatures, pointed out that the ore district is in the same belt as the Tibet Yulong porphyry copper-molybdenum ore deposit,with typical planar alteration being distinctive,and that the enriched chalcophile Au, Ag,Cu and Pb elements are sourced from por- phyry stocks of different sizes, indicating the potential for further exploration of porphyry copper-gold ore deposit in this area.
