| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
