摘　　要：综述了近年来造山带型金矿床、浅成低温热液型金矿床、卡林型金矿床以及块状硫化物矿床等不同类型矿床中"不可见金"的研究进展,探讨了"不可见金"的形成机制。微束分析技术能定量分析和给出元素分布图,波谱法是通过解谱来确定元素的化合价。研究中存在的问题主要有微束分析技术的分辨率和灵敏度还有待提升、波谱法解谱难以及晶体化学和热力学数据的缺乏。最后提出了研究"不可见金"赋存状态的意义及前景展望。The advances in the study of ＂invisible gold＂ in different gold deposit types are reviewed,including orogenic gold deposits,epithermal gold deposits,Carlin and massive sulfide ore deposits.This paper discusses the possible mechanisms for ＂invisible gold＂ formation and comments the advantages and disadvantages of microbeam analysis techniques and wave spectroscopy.Microbeam analysis techniques are used to do quantitative analysis and give the element distribution map,and the wave spectroscopy can give the valency of element.However,some problems have not been solved thoroughly as follows： the resolution and sensibility of microbeam analysis techniques,the analysis of wave spectrum and the incomplete of crystal chemistry and thermodynamics.Finally,the significance and prospect of studying ＂invisible gold＂ are proposed.
