中文摘要: Camel 1金矿是澳大利亚Pilbara地台最重要的金矿之一,矿区地表被第四系风成沙和冲积物覆盖,地表矿化信息少,找矿难度大。鉴于此,在该矿区引入“数字矿山”技术手段,结合Camel 1金矿的地质特征,特别是控矿构造特征,使用Surpac软件,建立Camel 1金矿矿化域三维模型,综合研究Au矿化空间分布规律。结果表明:Camel 1矿床Au矿化沿Mallina韧性剪切带东西向分布,且严格受Mallina韧性剪切控制;Au矿化与矿区后期北东向构造关系密切,沿北东向构造方向Au矿化具有较好的连续性。该方法也为该区以后的找矿工作提供了新的思路。
Abstract:The Camel 1 is a very important gold deposit located in the mallina ductile shear zone of northwest Australia; however, there are hardly any marks of ore-finding since the land is mainly covered by the Quaternary alluvial and aeolian sand and therefore there are rarely bedrock outcrops. Thus, based on the method of ‘digital mine’ and the geological structural characteristics in this area, this study chose to use the software of Surpac by which the delineation on mineralization domain model of Camel 1 gold deposit has at last been acquired. After analyzing the rules and characteristics of spatial distribution for that model, the rules of distributions for gold mineralization have been successfully predicted. The research shows that gold mineralization with low grade which locates along the mallina ductile shear belt has a good persistence, the gold mineralization in the connected positions of the northeastern structure and the mallina ductile shear belt is also well, and that along the direction of the later northeastern structure the gold mineralization persists well. In addition, three targets for ore-finding have been found out according to the results above.
