| 摘 要： | 通过对白弄铜金矿床详细的地质构造背景、含矿岩石及产出特征等研究表明,测区班怒结合带内铜金矿不具有斑岩型矿床特征,其与班怒洋在早白垩世双向俯冲、碰撞形成的闪长岩、石英闪长岩关系密切,依此把测区内班怒结合带内的铜金矿床确定为白弄闪长岩型-矽卡岩型铜金矿床,进一步完善了班怒结合带西段铜金矿矿床的类型,为今后在班怒结合带内寻找铜金矿矿床提供了新的资料。

| Abstract: | In this paper, the regional geological background and characteristics of ore-bearing rock in Bainong copper-gold deposit had been studied. The characteristics of the copper-gold deposits were incompatible with porphyry deposit and were quite close with diorite and quartz diorite which were formed in early Cretaceous during subduction of Bangongco-Nujiang ocean. On these bases, we proposed that Bainong deposit was related to the diorite and was a skarn type deposit. These achievements further perfected deposit types in the study area and provided new data for copper-gold prospecting in Bangongco-Nujiang River metallogenic belt. |
