| 中文摘要: |
| 澳大利亚布罗肯希尔地区是世界上最主要的多金属成矿区之一,仅位于其市内的主铅锌矿体累计开采及探明储量矿石超过2.5亿吨。除此之外,域内还有其他超大型、大型铅锌银金铜多金属矿床、铁矿床、钴矿床、银铅矿床、钨矿床等,小型矿床(点)无数。区域主要出露含矿地层古元古界威利玛超群,是由一套连续的变质程度不同的且多期变形的沉积岩和火山岩形成。位于其内的CUSIN溪矿区成矿地质环境及条件与本区其他矿床基本类似,在勘查中对其矿床(点)地质特征认识分析,发现矿区有热泉型矿床特征,结合区域地质背景、物探及探矿成果,认为本区具有潜在找矿潜力。 |
| 英文摘要: |
| Broken Hill is one of the most important polymetallic metallogenic areas in Australia of the world. The cumulative mining and proven reserves of the main Pb-Zn orebody in Broken Hill alone exceed 250 million tons. In addition, there are many super-large and large Pb-Zn (Ag、Au、Cu) polymetallic deposits, Fe deposits, Co deposits, Ag-Pb deposits, W deposits and numberous small deposits (spots) and so on in the area. The main ore-bearing strata in the metallogenic region are paleoproterozoic Willyama Supergroup. The ore-bearing strata are composed of a set of continuous sedimentary rocks and volcanic rocks which have different metamorphic degrees and undergo multi-stage tectonic deformation. Cusin River mining area is located in this area and its metallogenic geological environment and conditions are basically similar to those of other deposits in this area. From the analysis of the geological characteristics of the deposits (points) in this area, it is found that there are characteristics of hot spring type deposits in the mining area after the exploration works. Combining with the geological background, geophysical prospecting and geological engineering work in this area, it is considered that it has certain prospecting potential in the area. |
