摘　　要：龙口市大磨曲家金矿位于招平成矿带北端,玲珑金矿田东风特大型金矿床的北东部。该文对矿区的水系沉积物异常、地表岩石测量异常进行了解释与评价,研究分析了80线、84线剖面上多元素原生异常的形态、结构、组分等特征,建立大磨曲家金矿床“Y”字型构造叠加晕理想模型,论述了地球化学异常垂直纵投影图的特征,划定了成矿预测区,阐明了异常与金矿体的关系,指明了该区的找矿方向与地球化学指标。Longkou Damoqujia gold deposit is located in the north of Zhaopin mineralization belt , the north - east of the Linlong and Dongfeng large - size gold deposit. This paper interpretes and appraises the stream sediment anomalies and rocksurvey anomalies. Studies the multielement primary anomaly structure , shape and component features of profile 80 and 84. The ＂Y＂ shape structure superimposed halo is put forward . The features of geochemical anomaliy vertical longitudinal project profile diagram is discussed. The relation of gold ore body and anomalies is illustrated, Prospecting direction and geochemical zoning index is pointed out.
