摘　　要：烟筒桥子金矿床是以隐爆角砾岩筒型矿化为主体的金矿床,以矿区3号矿体为主要对象,通过对该矿体岩、矿石微量元素的地球化学分析,探讨了该类矿体地球化学特征。结果表明,在所分析的12种元素中,Au与Ag、Bi、Pb和Zn元素具有相似的富集趋势。这些元素的的富集规律可用于隐爆角砾岩体中金矿体的找矿标志之一。The Yancong Qiaozi gold deposit is dominated by hydrothermal brecciation pipe type mineralization.Taking the No. 3 ore body as the main example.the author discussed the geochemical characteristics of this kind of ore body through the geochemical analysis of lithological trace elements in the ore body.The results showed that among the twelve analyzed elements,the Au is a similar trend of enrichment with Ag,Bi,Pb and Zn,The enrichment rules of the elements can be used as one of sign prospecting the gold body of hydrothermal brecciation pipe type mineralization.
