中文摘要:文章通过野外地质观察，结合岩矿鉴定、化学分析、稳定同位素测定、稀土元素分析、成岩成矿同位素年龄测定、包裹体测温及成分等的研究，表明四川盐源模范村矿床具有典型斑岩铜矿的特征。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了中型规模的Ⅰ号矿体，影响次生富集带发育的F7断裂带起了重要作用。模范村矿床确系典型的斑岩铜矿，但又具独自的成矿特征。
Abstract:Based on field geological observation in combination with such indoor means as rock and mineral identification, chemical analysis, various isotopic determinations, REE analysis, isotopic dating for rocks and minerals, inclusion thermometry and composition analysis, the authors have reached the conclusion that the Mofancun ore deposit has typical characteristics of the porphyry copper deposit. The polyphase rock_forming process resulted in the formation of a composite intrusive body, and cryptoexplosion cataclastite pipe controlled by the fault structure provided the channelway and sedimentation space. The polyphase mineralization, especially the secondary enrichment, led to the formation of the medium_size No. I ore body. F7 fault, which affected the development of the secondary enrichment zone, played an important role in this process. Being a typical porphyry copper deposit, the Mofancun deposit also has its unique metallogenic characteristics. Such a phenomenon has a very important significance in guiding the ore-prospecting work.
