摘要
通过对1:50000水系沉积物测量数据的处理和研究,分析了河北六沟-小寺沟-杨树岭一带的地球化学特征,认为该区有较大成矿找矿潜力,尤其是金、铜、钼、银、铅、锌、铁矿床;圈定的综合异常与已探获的多金属矿产地对应良好,表明本区内多金属找矿工作具有明显的区域规律性和特定性,即同一成矿类型的找矿经验普遍适用,矿种与其特定的地层、岩体或构造相对应。因此总结了以分布在岩体或岩体与围岩接触带的异常、分布在构造发育地区的异常和分布在特定地质单元中的异常为今后的找矿方向。
Based on the processing and research of 1:50000 stream sediment survey data,this paper analyzed the geochemical characteristics of Liugou-Xiaosigou-Yangshuling area in Hebei province,and concluded that the area had great potential for ore-forming and prospecting,especially gold,copper,molybdenum,silver,lead,zinc and iron ore deposits.The delineated comprehensive anomalies corresponded well with the proven polymetal deposits,which showed that the polymetallic prospecting work in the area had obvious regional regularity and specificity,that is,the prospecting experience of the same metallogenic type was generally applicable,and the ore type corresponded to its specific stratum,rock mass or structure.Therefore,it is concluded that the anomalies distributed in the rock mass or the contact zone between the rock mass and the surrounding rock,the anomalies distributed in the structural development areas,and the anomalies distributed in the specific geological units are the prospecting directions in the future.
