小西南岔富金铜矿床是延边内生金铜成矿区重要的矿床,自20世纪70年代末发现该矿床以来,至今倍受国内外地质学家关注,围绕其金铜成矿与岩浆作用关系的地质、地球化学方面已有深入的研究(芮宗瑶等,1995a,b;孟庆丽等,2001),但在其成岩成矿年代学方面还显得薄弱。目前,获得的几组相 The Xiaoxinancha gold-bearing copper deposit is an important deposit in the Yanbian endogenous gold-copper mineralization area. Since the discovery of this deposit in the late 1970s, it has received much attention from geologists both at home and abroad. Based on its gold-copper mineralization and magmatism The relationship between geology and geochemistry has been intensively studied (Rui Zongyao et al., 1995a, b; Meng Qingli et al., 2001), but also appears to be weak in its diagenetic mineralization. At present, several groups of phases are obtained
