澳大利亚布罗肯希尔—艾文铜钴多金属矿床地质特征与找矿工作研究

Gological Characteristics and Prospecting of rokenshill-Aven Copper-Cobalt Polymetallic Deposit in Australia

澳大利亚布罗肯希尔-艾文铜钴多金属矿床地表工作显示,Cu的品位高、厚度大、断续延伸长,综合地质、地球物理、地球化学等特性,具有很好的找矿前景。经少量钻孔验证,未能发现地表矿体沿倾向延伸,找矿工作受阻。本文试图通过对地质背景、矿床地质、地球物理、地球化学特征等的综合研究,对比邻区相似矿床,提出了矿(化)体沿主断裂和韧性剪切带内呈斜列式排列并向南西侧伏的空间分布推断,对今后地质找矿工作具有重要的现实指导意义。

Surface work of Brokenhill-Avon Copper-Cobalt Polymetallic Deposit in Australia shows that copper has high grade,large thickness,long intermittent extension,comprehensive geological,geophysical and geochemical characteristics,and has good prospecting prospects.Verified by a small number of boreholes,it was not found that the surface orebody extended along the dip,and the prospecting work was hindered.Based on the comprehensive study of geological background,deposit geology,geophysics and geochemistry,and comparing the similar deposits in adjacent areas,this paper proposes that the ore bodies are arranged obliquely along the main faults and ductile shear zones,and the spatial distribution is inferred,which has important practical guiding significance for future geological prospecting work.
