摘　　要：综合地气测量是针对伟晶岩稀有金属矿找矿需求建立的地气测量与X荧光测量联袂探测隐伏矿的综合找矿技术,其中基于手持式X荧光仪进行快速测量,用于捕获地表的次生晕或原生晕,完成对含矿伟晶岩脉在地表的赋存位置、走向及延伸长度的评价;通过动态地气测量捕获深部矿化信息,用于评价伟晶岩脉的深部含矿性及延伸深度。本文介绍了这种综合找矿技术的主要技术方法,以及在有关项目支持下在不同地球化学景观环境下开展的找矿应用示范实例,以期为该方法的推广应用及后续同类景观区的找矿工作提供借鉴。The integrated geogas survey is a prospecting technology that integrates geogas survey and X-ray fluorescence measurement for exploring concealed ores based on the prospecting needs of pegmatite-type rare metal deposits.This technology utilizes handheld X-ray fluorescence instruments for rapid measurement to capture secondary or primary halos on the surface,enabling the evaluation of the occurrence positions,strikes,and extension lengths of ore-hosting pegmatite veins on the surface.Moreover,it employs a dynamic geogas survey to capture deep mineralization information for evaluating the deep ore-bearing potential and extension depths of the peg-matite veins.This study demonstrated the main technical methods of the integrated prospecting technology and the application cases of ore prospecting supported by relevant projects in different geochemical landscape environments,in order to provide reference for the ex-tension and application of this method and subsequent prospecting word in similar landscape areas.
