摘　　要：矿物中的流体包裹体记录了地球古流体的形成和演化、矿物的形成环境等各种地质信息。利用微区微量测量技术测定断裂带脉石矿物流体包裹体可以获得断层和地震活动的信息,延长认识地震复发周期的时间,对确定地震活动规律有重要意义。迄今为止,地震流体研究主要是关于宏观区域流体(水和气体)变化规律及其与地震的关系,对微区微量流体的研究很少。本文扼要介绍了地震和构造活动中流体作用与流体包裹体拉曼光谱测量技术,综述了流体包裹体(FI)分析在地震与断裂活动方面的研究进展,并提出了进一步研究的领域,以期促进微区微量地震流体研究和应用。Fluid inclusions in minerals record many kinds of information about formation and evolution of paleofluids in the Earth,environment of mineral formation,etc.Measurement of fluid inclusions by the techniques of micro area and trace amount analysis can help to obtain information about earthquake and fault activities.Investigation of paleoearthquake using analyzing fluid inclusion in minerals in veins can extend the time scale for studying earthquake recurrence period,which is significant for seismic study.So far,seismic researches of fluids mainly concern correlation between law of fluid variations(water and gas)in the macro regions and earthquakes,but rarely for trace fluids in minerals.In this paper we briefly introduced fluid role in earthquake and fault activities and techniques for analyzing fluids inclusions,and reviewed advance of investigations for earthquake and fault using analyzing techniques of fluids inclusions,and finally suggested the further related research aspects.
