摘要
通过对哈达门沟金矿床不同地质体的同位素年龄测定 ,野外观察各地质体之间的空间关系 ,研究矿床中各种矿物的形成阶段、矿物之间的蚀变交代穿插关系、成矿物理化学条件的变化等 ,确定矿床的形成时代为华力西晚期 ,主成矿期可划分为金 石英 钾长石、金 多金属硫化物 石英、金 黄铁矿 石英、金 石英 碳酸岩
Based on the isotopic age determination and the field observation of the spatial relationship of the different geological bodies in Hadamengou gold deposit, the minerals forming stages, and relationships among alteration, replacement and penetration in minerals, and some physical-chemical conditions changes of mineralization are studied, it is found that the forming time of the deposit was at late-Variscan, and the major metallogenic epoch was divided into 4 stages: gold-quartz-potash feldspar, gold-multimetal sulfide-quartz, gold-phyrite-quartz and gold-quartz-carbonatite stage.
