摘　　要：通过研究河北省宣化张全庄金矿地气样品中成矿元素,微量元素和稀土元素含量和空间分布特征,发现异常地气元素组合与矿石中成矿元素组合基本一致,亲铜或亲硫元素明显富集,与矿体空间基本吻合。背景区地气组分丰度主要受周围地质体控制,地气异常物质除来自其周围介质外,主要来自矿(化)体,据此可用于隐伏矿勘查。Study on the ore-forming elements,trace elements,REE and their Spatial distribution of the geogas in the Zhangquanzhuang gold deposit shows the anomaly compositions of the geogas over the mineralized zones are rich in chalcophile elements,and their element association is consistent with the ore body＇s,and also its spatial site.The abundance of elements in background geogas is controlled by geological bodies around.The elements in the anomaly geogas come only partially from the adjacent geological bodies,mainly from underlying ore bodies.The geogas survey can be used as a tool for hided ore body exploration.
