研究区位于扬子准地台西南缘,是川、滇、黔铅锌多金属矿集区的重要组成部分。研究矿石及围岩的微量元素地球化学特征,目的是探寻矿床类型和矿床成因。深入研究矿区及外围元素的地球化学背景,可以进一步探讨矿床成因。采用了两种分析方法:1)分析矿石及围岩的微量元素配分曲线;2)利用SPSS数学统计软件对微量元素数据进行分析。通过总结分析结果的诸多特点,得出以下结论:1)该矿床矿体与围岩来源具有一致性,围岩可能为矿源层;2)该矿床具有沉积+改造型矿床的特点。
The research area is located in the southwestern margin of the Yangtze Platform. It is an important part of the lead-zinc-polymetallic ore deposits in Sichuan, Yunnan and Guizhou. Studying the trace element geochemical characteristics of ores and surrounding rocks, the purpose is to explore the types of deposits and the genesis of the deposit. Studying the geochemical background of the mining area and its peripheral elements can further explore the genesis of the deposit. Two analytical methods were used: 1) trace elements distribution of ores and surrounding rocks; 2) analysis of trace element data using SPSS software. By summarizing the many characteristics of the analysis results, the following conclusions can be drawn: 1) The ore body of this deposit is consistent with the source of surrounding rock, and the surrounding rock may be the source rock; 2) This deposit has the characteristics of sedimentary + remodeled ore deposit.
