摘　　要：该矿床具有典型斑岩铜矿特征,成岩的多期次构成复式岩体,断裂构造控制的隐爆碎裂岩筒为成矿提供了通道和沉积场所。多期次成矿,特别是次生富集作用形成达中型规模的Ⅰ号矿体,影响次生富集带发育的F7断裂带起了重要作用。总结出适合本区斑岩群特点的找矿标志和提出的找矿靶区,对开展新一轮普查找矿具有现实意义。The deposit is characteristic of typical porphyry copper deposits. Ore - bearing porphyry is a multiple rockbody. Cryptoexplosive breccia pipe controlled by fractural structures was not only channel for ore fluids but also site for ore settling. Multiple ore - formation, especially, secondary enrichment controlled by fracture zone F7 resulted in medium - scale orebody I . Prospecting criteria and prospecting targets suitable for features of the porphyry group in this region put forward by this paper are of importance to the searching for porphyry copper deposits.
