摘要: 阐述了德合龙洼铜金矿的区域地质和区域地球化学概况,并分析了该区的成矿地质条件。采用1∶5 000次生晕普查方法,获得了Au、Cu、Ag、Pb、Zn等元素异常。次生晕异常反映了铜金矿化的存在,Au、Sn、Pb、Zn、Cu是重要的指示元素。异常与断裂构造控制的矿化形态及产状关系密切,进一步说明该区铜金矿是以断裂控矿为主。

Abstract: The paper describes the regional geology and geochemistry of the Dehelongwa Cu-Au deposit and analyzes the ore-forming conditions.Comprehensive anomalies of elements such as Au, Cu, Ag, Pb and Zn were discovered in a 1/5,000 secondary halo reconnaissance.The secondary halo abnormities reflect the existence of Cu-Au mineralization, and Au, Cu, Ag, Pb and Zn are the important indicator elements .The abnormities are closely related with the mineralization forms and occurrences controlled by the faulted structures, further illustrating  that the copper-gold ore in this area is mainly fault-controlled.
