中文摘要：锂、铍等稀有金属矿产是重要的战略矿产资源。近年来，在阿尔金地区发现了多处稀有金属伟晶岩型矿床，已成为我国一处新的稀有金属成矿带，但调查研究水平总体较低。通过对阿尔金造山带的成矿动力背景的讨论，得出阿尔金造山带的稀有金属成矿作用涵盖了多个不同的造山运动构造演化阶段，证明该区域具备良好的稀有金属成矿条件，并具有巨大的找矿潜力。通过对位于阿尔金西段的瓦石峡南锂铍稀有金属矿进行勘查评价，发现其具有大型远景:瓦石峡南锂铍稀有金属矿体主要赋存于绿片岩相-角闪岩相变质岩系中的伟晶岩脉中，矿床类型为花岗伟晶岩型稀有金属矿床;已有勘查成果显示此矿床目前推断的稀有金属资源量达到中型以上矿床规模，并且随着勘查工作的进行，在深部及外围还有极大增储空间。研究成果对在阿尔金造山带内寻找同类型矿床具有借鉴意义。

外文标题：Metallogenic background and exploration progress of the southern Waishixia lithium-beryllium rare metal deposit in the western Altyn Tagh of Xinjiang Province

外文摘要：Rare metal minerals such as lithium and beryllium are important strategic mineral resources.In recent years,several rare metal pegmatite-type deposits have been discovered in Altyn area,which have emerged as a new rare metal metallogenic belt,but with relatively low investigation and research level.Through the discussion of the metallogenic dynamic background of the Altyn orogenic belt,the authors concluded that the rare metal metallo-genesis in the Altyn orogenic belt covered many different tectonic evolution stages of the orogenic movement,indica-ting good metallogenic conditions for rare metals and great prospecting potential.The southern Waishixia lithium-beryllium rare metal deposit located in the western Altyn Tagh has a large prospect,based on the exploration and e-valuation of this deposit.The lithium-beryllium rare metal ore body in the southern Washixia mainly occurs in the pegmatite veins of greenschist facies and amphibolite facies metamorphic rock series,and the deposit type is gran-ite-pegmatite type rare metal deposit.According to the existing exploration results,the inferred rare metal re-sources of this deposit have reached the scale of medium and above,and there is still a great space for increasing storage in the deep and peripheral areas with the progress of exploration.The research results are of great refer-ence significance to the deposit search of similar types in the Altyn orogenic belt.
