摘 要：1 Geological features in the deposit THE Xifanping porphyry is located in the Yanyuan-Lijiang fault block at the southern margin of theYangtze massif. Only the Upper Permian Leping Formation and the Lower Triassic Qingtianbao Formation are exposed in Yanyuan County, Sichuan Province. The main ore-bearing rock body (No. 80) is anear-equant irregular complex stock, about 900 m long from east to west and 720 m wide from north tosouth. The bulk part consists of megaphyric biotite-quartz monzonitic porphyry. The commercial orebodylies in the No. 80 rock body and its surrounding country rocks, an N-S-elongated irregular lens-shapeddeposit. The orebody is controlled by the K-feldspar-biotite and quartz-sericite alteration zones. It consists mainly of disseminated and veinlet-disseminated ores.
