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。
The research results of the Pb-Zndeposit are introducted in this paper,taking Xitieshan lead-zinc deposit in Qing hai as a sample,emphasizes on the distribution of Cadmium and Iron.We condufcted comparative stude 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 significanc3e.From the mineralogy perspective,the results provide an evidence of an obvious overturn during the mineralization period Our condlusion lays a strong base for further research on the mineralization process of the deposit.
