黔南独山锑矿田找矿突破思路及找矿模型

Prospecting Thinking and Model of the Dushan Antimony Ore Field,Guizhou Province,China

独山锑矿田是贵州省重要的锑产地之一,矿田内多数矿床面临资源枯竭,急需深部外围找矿突破以延续矿山的生产。目前对矿田内的找矿模式研究较少,尚未建立适合现阶段勘查程度的找矿模型,在本次勘查工作中半坡矿床外围取得了较大的找矿突破。在此基础上,总结了本次找矿工作的思路,建立了预普查阶段的找矿模型,填补了矿田找矿模型方面的研究空缺。本次实现突破的勘查方法组合为:地质+岩石地球化学+地球物理(CSAMT)+钻探。

Dushan antimony ore field is an important part of the antimony ore belt in South China. In the ore field a majority of Sb deposits are facing the resources depletion, and so the prospecting breakthrough is badly needed to continue the mine production. In this prospecting work we have achieved important progresses, and on this basis summarize the prospecting thinking and establish the prospecting model. The prospecting methods of this work are combine the methods of geology ＋ petrogeochemistry ＋ geophysics （CSAMT） and＋ drilling.
