摘　　要：云南新平大红山铁铜矿区自1959年首先发现磁异常以来,对于区内发育的石英钠长斑岩,在其成因以及岩体与成矿的关系等认识上不一致、争论较多。本次根据大红山铜矿勘查和开采工程揭露,结合区域地质和矿区地质科研成果研究,认为石英钠长斑岩不是喷出岩,而应该是浅成侵入岩,其对I号矿带铜成矿元素具有明显的活化迁移与富集作用。Since the first magnetic anomaly was discovered in Dahongshan iron-copper mining area in Xinping County,Yunnan Province,there have been inconsistencies and debates about the development of quartz albite porphyry in the area for its origin and the relationship between rock mass and mineralization.According to the exploration and mining project of Dahongshan copper deposit,combined with the scientific research result of the region geology and the mining area,it is considered that the quartz albite porphyry is not an extrusive rock,but should be a shallow intrusive rock.It has an obvious activation migration and enrichment function for the copper mineralization element in the No.1 ore belt.
