| 摘 要： | 文章在梳理分析相关文献的基础上,综合考虑区域构造成矿背景、超大型金矿形成条件、金矿脉形成深度及隆升剥蚀幅度等方面的因素,认为哈达门沟—柳坝沟金矿田经历了漫长的地质演化,是多期次叠加成矿;在海西中、晚期初步富集,到印支期大规模成矿,再到燕山期进一步叠加富集并遭受后生改造;主成矿期为印支期,主成矿年代集中于217～240 Ma之间.

| Abstract: | Based on the analysis of related literatures, regional tectonic background, ore-forming conditions of super large gold deposits and formation depth of gold ore veins and the uplift and denudation rate etc it is considered that Hadamengou-Liubagou gold field is exposed to prolonged geological evolution. Multiple ore stages were superimposed with primary enrichment of gold in Middle-late Hercynian period and large scale ore-forming process in Indo-Chinese epoch. During Yanshanian period further superposition and enrichment and epigenetic rework took place. In the ore field Indo-Chinese epoch is the main metallogenic epoch and the metallogeny was concentrated in 217-240 Ma. |
