| 摘 要： | 通过对刘家堡子-狼洞沟金银矿床地质、成矿元素和同位素地球化学特征的分析和研究,发现矿区内近EW向和NE向断裂构造是主要容矿构造;最佳找矿元素前缘晕组合为As-Sb-Zn,矿上晕元素组合为Au-Ag-Pb-Hg,尾晕元素组合为Ni-Cu-Co;成矿作用中,古老基底中元古宙老岭群变质岩系为成矿提供了丰富的物质来源,而燕山期构造岩浆活动在提供成矿物质的同时还提供了热动力。刘家堡子-狼洞沟金银矿床应划属为与燕山晚期超浅成中酸性岩浆岩有关的中低温热液构造裂隙充填型金银矿床。

| Abstract: | Through analysis and study on geology, oreforming elements and isotopes geochemical characteristics of Liujiapuzi Langdonggou gold and silver deposit, it is found that the faults with the trend of EW and NE were main orebearing structures, the best prospecting elements combination of front halo was AsSbZn, superore halo was AuAgPbHg, and tail halo was NiCuCo. Metamorphic rock series of Proterozoic Laoling group in the ancient base provided rich material sources for mineralization, and Yanshanian tectonic magmatic activities provided oreforming materials as well as thermodynamic. Liujiapuzi Langdonggou gold and silver deposit should be classified into midlowed hydrothermal and structural fissure filling type gold and silver deposit associated with super hypabyssal intermediateacidic magamtic rocks in late Yanshanian. |
