| 摘 要： | 介绍了冀北围场县锥子山一带各个期次侵入岩体的地质、岩石化学及地球化学特征,论述了各期次岩体的酸碱度、成因类型以及微量元素的富集分异性。从成矿专属性、物质来源、酸碱度对成矿流体的影响以及元素的富集分异趋势等方面,分析该区侵入体的成矿有利因素,认为侵入体与围岩的内外接触带、侵入体与构造结合部位是寻找Au、Ag、Pb、Zn、Cu和Mo等金属矿床的有利地段。

| Abstract: | In the paper, the authors introduced geological, geochemical and lithochemical characteristics of different period intrusions in Zhuizi Mountain of Weichang Country, North Hebei. And the pH, genetic types and enriched differentiation of trace elements were also discussed. Based on the metallogenic relation, material source, the effect of pH on metallogenic fluid and enriched differentiation of trace elements, the authors analyzed the metallogenic advantages of different period intrusions in the study area. The results show that the inner and outer contact zones between intrusions and surrounding rocks and the joint sites of the intrusions and structure are the favorable locations for metallic mineral deposits, such as Au, Ag, Pb, Zn, Cu and Mo. |
