通过同位素年龄测定和对哈达门沟金存款矿床不同地质体空间关系的野外观察，研究了矿床的成矿期次，矿物中蚀变、交代、渗透的关系，以及成矿的某些物理化学条件变化，发现该存款的成矿时代为华力西晚期，主要成矿期分为金-石英-钾长石、金-多金属硫化物-石英、金-斑岩-石英和金-石英-碳酸盐岩4个阶段。
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.
