| 中文摘要: |
| 通过对威宁县黑石头铜矿床矿体空间分布及矿石特征进行综合分析,认为该区铜矿主要矿源层为岩浆喷溢间断面的玄武岩及玄武质凝灰岩,区域构造为含矿热液提供了通道,次级小断裂和背斜褶皱倾伏端复合(叠加)部位、断层破碎带中碎裂状节理、裂隙以及多孔的玄武岩为成矿物质提供了富集沉淀的空间。铜矿在暴露地表后,发生了表生氧化及次生富集作用。在此基础上,分析了成矿条件,并依据成矿条件圈出5个找矿远景区。 |

| By analysis the orebody spatial distribution and ore features of Weishitou copper deposit in Weining, it’s thought the mineral resource layer of this deposit are the basalt and basaltic tuff of magmatic eruption discontinuity surface, the regional structure affords tunnel for ore-bearing hydrothermal solution. The composite part of secondary small fault and anticline fold Plunging position, crushing joint of fault fracture zone, fracture and porous basalt afford the space of concentration and precipitation for mineral materials. After the copper deposit exposed on the ground, it experienced supergene oxidation and secondary enrichment. On this basis, the metallogenic conditions were analyzed and then 5 prospecting potential zones were determined. |
