摘　　要：玄武岩覆盖区找矿一直是矿产资源勘察中的热点与难点,而地球化学求异则是覆盖区找矿研究的重中之重。本文应用地球化学元素空间定量组合求异理论,对和龙地区地球化学元素数据进行处理与分析,求出该地区组合元素空间分布信息。并结合相关地质特征,阐明该区地球化学元素空间分布特征及与成矿的关系,为该区矿产资源勘查靶区的圈定提供重要依据。The prospecting in coverage area by basalt is a hotspot but also a difficulty in the exploration of mineral resources, which is paramount importance is geochemical difference. This paper analyzed geochemical survey data of Helong area with the spatial quantitative combined anomaly analysis method, and worked out the spatial distribution information of the combined elements, and elucidated the its relationship with mineralization based on relevant geological features. It could provide an important basis for the delineation of mineral resources prospecting target areas.
