中文摘要: |
文章以青海锡铁山铅锌矿床为例,重点研究了闪锌矿中镉、铁的分布规律,对比分析了主要矿体中闪锌矿、不同矿石类型中闪锌矿、主要载体矿物中闪锌矿及闪锌矿晶体中的镉、铁分布,及其所蕴含的地质意义。从矿物学研究角度提供了矿床初始成矿时赋矿层发生明显倒转的证据,推测了不同矿石类型以及主要载体矿物的成矿温度序列,结合流体包衷体研究,提出该区矿液活动至少有4期,为矿床成矿规律研究提供了依据。 |
英文摘要: |
The research results of the Pb-Zn deposit are introducted in this paper, taking Xitieshan lead-zinc deposit in Qinghai as a sample, emphasizes on the distribution of Cadmium and Iron. We conducted comparative study on the distribution of sphalerite in the major orebody, other types of ore and major carrier mineral. In addition, we further study the respective distribution of Cadmium and Iron in various sphalerites and their geological significance. From the mineralogy perspective, the results provide an evidence of an obvious overturn during the mineralization period. We also infer the mineralization temperature sequence of different ore types and major carrier mineral, and conclude that there are at least four stages during the mineralization process. Our conclusion lays a strong base for further research on the mineralization process of the deposit. |
