摘　　要：为了探索CO_(2)和SO_(2)气体地球化学测量方法在森林覆盖区找矿的可行性,本次研究基于最新设计的气体快速分析仪器,对森林覆盖区吉林夹皮沟金矿集区开展了CO_(2)和SO_(2)气体地球化学测量方法的试验性研究。结果显示,在隐伏矿和隐伏构造上方均可发现明显的CO_(2)和SO_(2)异常,在森林覆盖区,CO_(2)和SO_(2)气体地球化学测量方法不仅能够反映断裂构造,而且对深部隐伏金矿具有良好的指示作用,对我国覆盖区找矿技术突破具有重要意义。This study aims to explore the feasibility of the carbon dioxide(CO_(2))and sulfur dioxide(SO_(2))gas geochemical survey method for mineral exploration in forested areas.Based on the newly designed gas rapid analysis instrument,this study conducted an experimental investigation of the method in the forested Jiapigou gold concentration area,Jilin Province.The results show that signifi-cant CO_(2)and SO_(2)anomalies were observed above the concealed ore bodies and structures.In the forested area,the CO_(2)and SO_(2)gas geochemical survey method reflected the fault structures and effectively indicated the deep concealed gold deposit.This method holds critical significance for the breakthrough of prospecting technology in China's covered areas.
