摘要
通过对店房、毛堂、蒲塘、祁雨沟金矿的研究，提出隐爆角砾岩型金矿以涌入、贯入相矿化好，震碎、坍塌相矿化较差，且角砾均一细小对矿化有利。本区该类型金矿均受控于中生代（中）酸性斑岩－隐爆角砾岩筒及与其相关的环状、线状断裂构造、接触带构造。总结了该区隐爆角砾岩型金矿矿床特征、成矿条件与评价标志，探讨了矿床成因及找矿前景。
Geology of the Dianfang,Putang,Maotang and Qiyugou gold deposits reveal that extinct mineralization was developed in different facies of breccia pipe,rich ore in injecting facies,low-grode ore in shattering and collapse.The small breccia pipe is conductive to mineralization which is confined to the Yanshanian acid porphgry,breccia pipe and their related circular,liear structures and contact zones.Based on the studies on geology and ore-controlling factors,the metallogenesis is discussed.
