长春市双阳区矿山主采矿层的微量元素特征分析

长春市双阳区矿山主采矿层受到来自侏罗纪时期的矿物侵入,影响了矿层性质以及微量元素富集赋存状态。本次研究主要基于ICP-MS测得的微量元素数据,结合研究区域矿物特征,分析矿物蚀变过程中的微量元素的变化情况,结果表明,矿层中轻微富集Ga、Rb、Sr、Ba、W、Hg元素,稀土元素的配分模式与岩浆侵入有着密不可分的联系。主采矿层中不同微量元素显示出不同的亲和性质,Ba、Hg元素在主采层中含量较大,其他微量元素相对比较稳定。

Analysis of the trace element characteristics of the main mining seam in Shuangyang District of Changchun City

The main mining seam in Shuangyang District of Changchun City was invaded by minerals from Jurassic period,which affected the properties of the seam and the state of trace element enrichment and occurrence.This study is mainly based on the trace element data measured by ICP-MS,combined with the mineral characteristics of the study area,to analyze the change of trace elements in the process of mineral alteration.The results show that the ore bed is slightly enriched with GA,Rb,Sr,Ba,W,Hg elements,and the distribution mode of rare earth elements is closely related to magma intrusion.Different trace elements in the main mining seam show different affinity properties.Ba and Hg elements are relatively large in the main mining seam,and other trace elements are relatively stable.
