摘　　要：溶解再沉淀过程可促进矿物-流体之间充分的反应,使一些元素再次迁移富集,在许多地质过程中扮演着重要角色。近年来,随着聚焦离子束透射电镜(FIB-TEM)、纳米二次离子质谱仪(Nano-SIMS)等制样观测及精细分析技术的发展,矿物界面化学研究取得了众多成果。已有研究证实,在低温、溶剂存在的条件下,溶解再沉淀过程相对于固体扩散是更高效的物质交换机制。本文回顾了溶解再沉淀过程的研究历史,综述了近20年来取得的主要研究进展,包括不同矿物相(硅酸盐、磷酸盐、碳酸盐矿物及氧化物、硫化物等)中主要鉴别结构特征、元素迁移富集规律及主要观测分析手段,系统总结了溶解再沉淀过程的主要影响因素,最后展望了其发展方向。The dissolution and reprecipitation process of minerals,play a crucial role in many geological evolution processes,can stimulate sufficient reaction between mineral-fluid interface and re-migration and re-enrichment of some elements.In recent years,with the development of sophisticated analytical techniques for sample preparation and in-situ observation analysis,including the focused ion beam combined transmission electron microscopy(FIB-TEM)and the nanoscale secondary ion mass spectrometer(Nano-SIMS),considerable achievements of researches on mineral interface chemistry have been obtained and published.It has been shown that the dissolution and reprecipitation process is a more efficient exchange mechanism for the material exchange compared to the solid-state diffusion especially under the condition of low temperature and presence of solvent.In this paper,we have reviewed the research history of the dissolution and reprecipitation process,summerized main research progresses on the process in the past two decades,including the identification characteristics of structures in different mineral phases(silicate,phosphate,carbonate minerals and oxide,sulfide minerals,etc.),the migration and enrichment regulations of elements,and the primary observation and analysis methods for relevant researches,systematically reviewed main influencing factors of the dissolution and reprecipitation process,and finally made a perspective on the future development direction in this field.
