摘　　要：隐爆角砾岩筒为热液成矿作用中十分重要的成矿结构面和矿化富集部位,同时是寻找深部矿体的重要标志。河北省彭庄隐爆角砾岩筒是冀东近年勘查的“三稀”矿产赋存靶区,岩筒内铷矿化较均匀,铍、钨局部富集,铍、银、钨等矿化体呈透镜状分布在铷低品位矿体中,各矿(化)体均受隐爆角砾岩筒控制。在以往矿产勘查基础上,主要对隐爆角砾岩筒地质特征和岩石地球化学进行深入分析,认为目前工程控制的岩筒内上部属低温蚀变角砾岩带,其下部应存在团块矿化、细脉矿化角砾岩带,深部可能有含矿斑岩体,对本区下一步找矿工作提供参考。The crypto-explosive breccia pipe is an important ore-forming structural plane and ore-forming enrichment position in hydrothermal mineralization,and it is also an important indicator for looking for deep ore bodies.The Pengzhuang cryptoexplosive breccia pipe is a occurrence target of"three-type rare resources"for mineral exploration in eastern Hebei in recent years,in which the mineralization of rubidium is uniform,beryllium and tungsten are locally enriched,and silver,beryllium and tungsten are lenticularly distributed in the low-grade ore body of rubidium,and that all are controlled by the pipe.Based on the previous mineral exploration,the geological and petro-geochemical characteristics of crypto-explosive breccia pipe was analysed.It is considered that the upper part of the pipe controlled by the current exploration engineering belongs to low temperature hydrothermal altered breccia belt,and there should be agglomerated mineralized and veinlet mineralized breccia belt in the lower part and may be even ore-bearing porphyry body in the deep part,which provides a reference for the next prospecting work in this area.
