摘　　要：由火山喷发、陨石撞击和太阳风及宇宙射线辐照等非平衡过程产生的玻璃物质是月壤的重要组成部分,这些不同成因的玻璃物质记录了月球起源和演化的重要历史信息.本文主要综述了嫦娥5号(CE-5)取回的月壤中月球玻璃的研究进展,包括其基本物性、微观结构、具体的形成机制以及它们在月球研究中的作用等.研究发现月球玻璃可以像天然照相机一样记录下不同年代月球内部和表面的演化信息,涉及月球的起源、岩浆活动、撞击环境、太空风化和水的来源等;月球玻璃稳定的无序结构还能够长期保存月球资源,据估计其存储的3He有26万吨,存储的水高达2700亿吨;月球玻璃类似月球上的时钟,能够作为火山活动和撞击事件的时间标尺,为研究月球水和磁场等的演化以及重构几十亿年的撞击历史提供重要支撑.Lunar glass,a significant component of lunar soil,is produced by non-equilibrium processes on the moon,such as volcanic eruptions,meteorite impacts,solar wind,and cosmic radiation.Lunar glass of different origins has ability to record historical information of the formation and evolution of the moon.This article presents a comprehensive review of the research progress of lunar glasses found within the CE-5 lunar soil.Delving into their fundamental physical properties and microstructure,we explore the specific mechanisms behind the formation of lunar glasses.Furthermore,this article focuses on the various roles that lunar glasses play in studies of lunar evolution,such as acting as a“natural camera”that captures the moon's internal and surface changes over different epochs,encompassing lunar origin,magma activity,impact events,space weathering,and the origin of water.The ultra-stable lunar glass with disordered atomic structure can sustainably preserve lunar resources.It is estimated that lunar glasses have reserved approximately 260000 tons of ^(3)He,and 27 billion tons of water.Moreover,lunar glasses serve as an invaluable lunar chronometer,providing a reliable temporal framework to data volcanic activity and impact events.This temporal framework,in turn,serves as a vital tool for investigating the evolution of lunar water,magnetic fields and reconstructing the extensive billion-year history of lunar impacts.
