摘　　要：为圈定锂成矿远景区,采用已有1∶20万地球化学数据,选取西昆仑-阿尔金和阿尔泰两个主要锂矿带,基于锂元素地球化学空间分布及异常特征圈定锂矿远景区,为找矿突破战略行动选区服务。基于重点锂矿带以往1∶20万地球化学数据库,对元素相关性、背景及异常特征等参数进行再分析,结合已有锂矿床或锂矿(化)点,圈定找矿远景区。在昆仑-阿尔金地区圈定锂地球化学异常区15处,在阿尔泰圈定锂地球化学异常区12处。研究圈定27处异常区可为下一步锂矿找矿工作部署提供参考依据。In order to delineate the prospecting area for lithium mineralization,1:200000 geochemical data in the two main lithium ore belts of West Kunlun Altun and Altay was used.Based on the geochemical spatial distribution and abnormal characteristics of lithium elements,the prospecting area was delineated to serve the strategic action selection for mineral exploration breakthroughs.Based on the previous 1:200000 geochemical database of key lithium deposit zones,the data were reanalyzed for parameters such as element correlation,background,and anomaly characteristics,and combined with existing lithium deposits or lithium mineralization points to delineate prospecting prospects.Fifteen geochemical anomaly areas for lithium have been delineated in the Kunlun Altai region,and twelve geochemical anomaly areas for lithium have been delineated in the Altai region.The 27 abnormal areas delineated in this study can provide reference basis for the next deployment of lithium ore exploration work.
