| 摘 要： | 桃园式铜矿产于黑山组底部黑色碳质板岩和凝灰质板岩中.矿石的微量元素特征、黄铁矿的Co/Ni比值、黄铁矿和黄铜矿的硫同位素特征表明,成矿热液主要来自深部,少部分来自海水；稀土元素特征显示还原成矿环境；主要成矿阶段在晋宁晚期的基性岩浆活动时,或稍晚时期.主要控矿因素为地层及岩相古地理、构造、岩浆活动和矿化浓集中心. |

| Abstract: | Taoyuan-type copper deposit is in black carbonaeous shale and tuffaceous slate at bottom of Heishan formation.Trace elements characteristics of ore,Co/Ni ratio of pyrite and sulfur isotope analysis of pyrite and chalcopyrite indicate that the ore-forming hydrothermal fluid mainly comes from depth,a few from sea water.Characteristics of rare earth elements show a redusced metallogenic environment.Its main metallogenic phase is in late Jinning period when basic magmatism took place or later.Strata,lithofacies and paleogeography,structure,magma activity and mineralization concentration center are the ore-controlling factors. |
| Keywords: | Taoyuan-type copper deposit Heishan formation ore-controlling factor Dongchuan copper deposit Yunnan province |
