| 1. | Study on metallogenic epoch and metallogenic stages of the hadamengou gold deposit , inner mongolia 内蒙古哈达门沟金矿成矿时代及成矿阶段研究 |
| 2. | Among them the precambrian and cenozoic eras are the main metallogenic epoches in the world 就全球而言,前寒武纪和新生代是金矿的重要成矿期。 |
| 3. | The author summarizes the distribution law of gold deposits of fujian in space and time and studies the metallogenic epoch using the method of isotopic geochronology and geologic analysis 总结了金矿的时空分布规律,采用同位素测年和地质分析相结合的方法研究福建省金矿的成矿年代。 |
| 4. | Based on systematic summarization of geological characteristics of the tianlu copper deposit , this paper has analyzed its metallogenic epoch and genesis , and built up a metallogenic model 摘要文章在系统总结天鹿铜矿床地质特征的基础上,分析了成矿时代和矿床成因,并建立了成矿模式。 |
| 5. | The results show that the ore - bearing strata occur in variegated strata of middle silurian quannaogoushan formation , that the metallogenic materials might have been derived from the land area , and the metallogenic epoch is middle silurian 结果表明,天鹿铜矿床赋存于中志留统泉脑沟山组杂色岩层中,其成矿物质来自陆源,主成矿期为中志留世,属沉积砂岩型铜矿床。 |
| 6. | It suggests that gold accumulation occurred in the every main stage of geologic history of fujian from late - archaean era to quaternary period but the scale and the feature of the gold accumulation are different in different stage and yanshan metallogenic epoch is the most important period of mineralization of fujian gold deposits 提出福建省内自晚太古代至第四纪的各个地质历史发展的主要阶段均有金的富集作用,但不同阶段所形成的金富集规模及特征明显有别,燕山期为福建省金矿最重要的成矿期。 |
