摘要 

为了研究CO2气体测量方法在低山丘陵区隐伏矿勘查的应用效果,采用改进的CO2快速分析仪分别对湖南黄金洞金矿区金枚矿段和梨树坪矿段进行了CO2气体测量试验性研究和面积性测量研究。结果表明,CO2气体测量方法在低山丘陵区能够发现深部隐伏矿和构造信息,并为梨树坪矿段圈定了3个找矿靶区,具有重要的实际意义,为我国覆盖区隐伏矿勘查突破积累了数据和经验。

Abstract：

To study the effectiveness of CO2 gas measurement method in the exploration for concealed mineral deposits in hilly areas,the authors carried out pilot study and area study by employing CO2 gas measurement with rapid gas analytical techniques at Jinmei ore block and Lishuping ore block of Huangjindong mining area,respectively. The results indicate that CO2 gas measurement method can discover the information around deeply buried mineral deposits and deep-seated structures. Having delineated three prospecting target areas for Lishuping ore block, it is proved to have important practical significance and can accumulate data and experience for concealed mineral exploration in covered areas.
Key words： gas measurement    carbon dioxide    hilly area    concealed deposit
