华北古陆块南缘金属矿床成矿机制研究

摘要

文章通过分析和总结前人的研究资料,认为华北古陆块南缘产出的金属矿床具有成矿机制的多样性:①构造—变质—岩浆—流体成矿,如小秦岭金矿等；②构造—岩浆成矿,如熊耳山金矿田、外方山铅锌铜矿、神洞沟银矿、与燕山期中酸性小岩体有关的钼钨矿等；③构造—建造—流体成矿,如刘山崖铜锌矿、围山城金银矿等；④岩浆—热液蚀变成矿,如秋树湾铜钼矿.%Analysis and study on the previous data about metal deposits at south margin of the north China palaocontinent reveal diversi fication of their metallogenic mechanism, I. E. ① tectonic-magmatic-fluid (Xiaoqinling gold deposit); ② tectonic-magmaticCXiongershan gold ore field, waifangshan Pb-Zn-Cu deposit, Shentonggou Ag deposit, Mo-W deposit associated with small Yanshanian intermediate-acidic in-trussive bodies etc.); ③tectonic-rock formation-fluid (Liushanya Cu-Zn deposit, Weishancheng Au-Ag deposit); ④magmatic-hydrothermal alteration (Qiushuwan Cu-Mo deposit).
