中文摘要: |
库鲁兹铜矿床位于南美玻利维亚钨锡成矿带内,属于Quimsa Cruz花岗岩体的外围矿床,矿体赋存于志留系地层中。文章以库鲁兹铜矿床最新勘查资料为依据,对矿区地层、构造、矿体矿化特征等进行了阐述,对矿床成因进行了探讨,认为库鲁兹铜矿为与菱铁矿伴生的热液交代型脉状铜矿床,受断裂控制,与志留系地层中的石英砂岩、页岩、炭质页岩等软硬岩组合和滑脱构造密切相关。 |
英文摘要: |
The Cruz copper deposit located in the Bolivian tungsten-tin belt, is a peripheral deposit outside of Quimisa Cruz granite, the host strata is Silurian quartz-sandstone, siltstone, shale and carbonaceous shale. The deposit consists of copper-bearing veins which occur in lenforms.Based on the newly exploration data, this paper introduce ore-bearing stratum, structures, ore body features and mineralization characteristics, then the deposit genesis was discussed. It is concluded that the deposit is a hydrothermal metasomatic deposit associated with the siderite deposit, and controlled by fractures, the mineralization is relevant to the combination of hard and soft rocks, and slip structures. Finally, the prospecting criteria for this type of ore deposit in the area is summarized. |
