四川省宁南县某铅锌矿床微量元素地球化学特征分析

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.

Analysis on the geochemical features of the trace elements about a Pb-Zn deposit in Ningnan county,Sichuan Province

The area is located in southwest of Yangzi paraplatform and the important part of the Sichuan-Yunnan-Guizhou multi-metal deposits.The purpose of studying the geochemical features of the trace elements about the ores and rocks is analysising on the type and causes of the deposit.In-depth studying the geochemical background of the area and surrounding elements can further understand the causes of the deposit.Two methods:1)Analyze the partition curve of the trace elements about the ores and rocks;2)Analyze the data of the trace elements by using the SPSS.The results,can be seen:1)The source of the ores are consistent with the rocks;2)The deposit has the features of the sedimentary and transforming deposit.
