摘要
在综合分析前期地质、化探资料的基础上,对河北省阜平县口子头隐爆角砾岩开展了1/1万岩石地球化学测量工作,圈定10处异常。钻探验证显示深部黄铁绢英岩化强烈,圈定5个钼矿体、7个银(金)矿体,估算钼金属量83t,银金属量10.67 t,伴生金金属量61.81 kg。银钼多金属矿体赋存于隐爆角砾岩体中,表明地表原生晕异常为矿致异常。钻孔原生晕元素含量分布图显示,主要成矿元素的结晶沉淀规律符合典型热液型矿床的元素分布特征。笔者还研究了矿体中元素的富集范围,预测了深部盲矿体的赋存部位,并提出进一步验证的建议。
1/10 000 rock geochemical survey for cryptoexplosive breccia was finished and 10 anomalies were delineated on the basis of comprehensive analysis of geological and geochemical data. The drilling verification shows that pyrite phyllic develops strongly, and five molybdenum ore bodies and seven silver （gold） ore bodies were found. The estimate amount of molybdenum metal is 83 t, silver 10.67 t, associated gold 61.81 kg. The primary halo anomalies belong to the the ore anomalies. The Ag-Mo multiple metal ore bodies occur in cryptoexplosive breccia. The element content distribution in primary halo of drilling displays that precipitation regularity of main ore-forming elements conform to the distribution pattern of the typical hydrothermal deposit elements. The authors researched the enrichment range of elements and calculated the occurrence site of blind ore body and made a recommendation for further validation
