摘　　要：甘南地区金矿探矿历史久远,所用勘查技术手段种类繁多,但甘南地区覆盖区面积大,覆盖厚,针对厚覆盖区技术手段相对较少。多组分气体地球化学测量技术可检测深部向上逸散的气体成分含量,从而反应深部成矿环境。本文通过多组分气体地球化学测量技术对加甘滩金矿区内气体异常特征及外围覆盖区气体异常特征进行了分析研究,预测了该区的找矿前景,试验了该方法的有效性。The exploration of gold deposits in the Gannan region has a long history and involves a variety of exploration techniques.However,the Gannan region has a large coverage area and thick coverage,and there are relatively few technical means for thick coverage areas.The multi-component gas geochemical measurement technology can detect the content of gas components escaping upwards from the deep,thereby reflecting the deep ore-forming environment.This article analyzes and studies the gas anomaly characteristics in the Jiagantan gold deposit area and the gas anomaly characteristics in the peripheral coverage area using multi-component gas geochemical measurement technology,predicts the prospecting prospects of the area,and tests the effectiveness of this method.
