硫化物矿物的主微(痕)量元素分析进展

Progress in Major Element and Trace Element Analysis of Sulfide Minerals

金属或半金属元素(Fe、Mo、As、Cu、Co、Ni、Zn、Pb等)、贵金属元素(Au、Ag)和铂族元素(PGE)、稀有分散元素(Re、Ga、In等)以高浓度富集或微量赋存于硫化物矿物中,常形成具有工业意义和经济价值的大型矿床,对研究矿床成因、经济地质、环境地球化学具有重要意义。因此,对硫化物组成的精确分析是了解上述方向的重要途径。硫化物矿物的主微(痕)量元素的快速、精确定量分析一直以来备受关注,本文就近几十年来对硫化物矿物的定量分析进展作了详细介绍,重点评述了电子探针(EPMA)、X射线荧光光谱(XRF)、电感耦合等离子体质谱(ICP-MS和LA-ICPMS)和电感耦合等离子体发射光谱(ICP-AES)在硫化物矿物主微(痕)量分析中的应用。

Metal or semimetal elements（Fe,Mo,As,Cu,Co,Ni,Zn,Pb and so on）,precious metal elements（Au,Ag and platinum group elements（PGE））,rare and dispersed elements（Re,Ga,In and so on） are highly enriched or hosted in sulfide minerals.They often form large ore deposits of industry significance and economic value,which play a significant role in the study on ore genesis,economic geology and environment geochemistry.Therefore,exact analysis of sulfide constitutes is an important way to understand above aspects.Rapid quantitative analysis of major and micro（trace） elements from sulfide minerals continuously attracts global attention.This paper was described in detail the development in quantitative analysis of sulfide minerals in recent decades,and four ordinary techniques,electron probe microanalysis（EPMA）,X-ray fluorescence（XRF）,inductively coupled plasma mass spectrometer（ICP-MS and Laser Ablation ICP-MS）,and inductively coupled plasma atomic emission spectrometry（ICP-AES）,were discussed particularly.
