| 摘 要： | 西秦岭是中国西北地区重要的有色、贵金属资源富集区。文章运用矿床成矿系列的理论和方法,对甘肃西秦岭地区进行矿床成矿系列和成矿谱系研究。初步厘定了7个矿床系列12个亚系列,分属2个成矿系列组合,以典型矿床地质特征分析为基础,根据各成矿系列在区域内的演化归结为成矿谱系。指出本区晚古生代、中生代成矿作用强烈,以与构造岩浆活动有关的金、铜(砷)、金(锑)、银、钼、钨锡矿床为主,以沉积岩容矿的层控热液型金、汞、锑、铅锌的大量发育为特征。基于成矿系列划分,在铅锌、金、钼矿产勘查实践中,取得了新的找矿突破。这对于深入研究区域成矿规律,指导矿产勘查工作具有重要意义。

| Abstract: | The West Qinling region in Gansu Province is an important ore concentration area of nonferrous metals and noble metals in northwest China. Based on application of theories and methods of the minerogenetic series, the authors divided the mineralizations in the West Qinling region in Gansu Province into 7 minerogenetic series and 12 minerogenetic sub-series, which belong to 2 minerogenetic associations of minerogenetic series and can be assigned to the minerogenetic lineage according to the evolution of each minerogenetic series in this region. It should be pointed out that there occurred strong ore-forming activities in Late Paleozoic and Mesozoic in the study area, where mineralizations related to magmatic activities are Au, Cu (As), Cu(Sb), Mo and W-Sn mineralizations, characterized by the formation of stratabound hydrothermal Au, Hg, Sb, Pb, Sn deposits hosted in sedimentary rocks. The study of regional minerogenetic regularity is of great significance in guiding the ore-prospecting work. |
