摘　　要：在对老东寨铅锌矿矿床地质研究的基础上,重点对矿床的微量元素进行研究,结合成矿元素特征、成矿温度等对成矿作用进行分析。结果表明:Cu、Cd、In、Sb、Pb、Zn等元素是随着成矿作用进入矿石的,该矿床为中低温矿化,成矿过程基本与岩浆作用无关,推测矿床为正常沉积+后期改造叠加形成。On the basis of study on geological characteristics of the Laodongzhai Pb-Zn deposit,focused on the research of characteristics of trace elements of the deposit,and combined the characteristics of ore-forming elements and metallogenic temperature to analyze the mineralization.The results of the study showed that Cu,Cd,In,Sb,Pb,Zn and other elements entered the ore along with mineralization.It is considered that the ore deposit is a medium-low temperature mineralization,and the metallogenic process basically has nothing to do with magmatism.It was inferred that the deposit had a primary Pb-Zn deposition basis,and enriched by the later superimposed reformation.
