摘　　要：冀东地区矿产资源非常丰富,但以往只把铁矿和金矿作为重点找矿目标,对钨矿等勘查重视程度不够。在亮甲峪地区进行1∶2.5万土壤地球化学测量工作,通过元素分布特征、单元素异常特征、元素相关性分析以及综合异常圈定,确定了找矿靶区;通过对Z1靶区进行土壤剖面测量,圈定了3条异常带,对异常带实施钻孔深部验证,发现金钨矿体,证明异常为矿致异常.Eastern Hebei Province has very rich mineral resources;nevertheless,the past prospecting work was focused only on iron and gold deposits,whereas the attention to tungsten deposits was very insufficient.Based on 1∶25000 soil geochemical survey,the authors conducted detailed soil geochemical survey in the Liangjiayu areaof Hebei Province.Through studying element distribution characteristics,individual element anomaly features,element correlation,and comprehensive anomaly setting combinational anomalies of related elements,the authors determined Au and W as the target ore species elements in the study areaand delineated further prospecting areas.
