摘要
论述了成矿带的构造演化、火山岩—侵入岩演化，剖析了它们与成矿的关系，认为额尔古纳成矿带金属矿产受统一的区域构造－ 岩浆活动控制，在各自独特的构造与建造环境中成矿，提出了本区域成矿系列的观点。在总结各类矿床的形成条件、成矿环境、成矿机制及成因等的基础上，提出了额尔古纳成矿带各矿床的空间模式，指出矿床的叠置不仅仅是垂向空间关系。
Erguna is an important ore belt for Ag, Pb, Cu and Mo metallisation in China. It is a complete metallogenic series related to volcanic rocks and porphyries. The evolution of structure, volcanism and magmatism, and its relation to metallisation, are mainly discussed. It is suggested that the deposits in this ore belt are controlled by the integrated tectonic and magmatic activities. Based on the studies of metallogenic condition, geological environment, metallogenic mechanism and origin, the metallisation model is established. It is proposed that the superimposition of mineral deposit is not only the spatial superimposition but also the transi-subbelt or transi-mines distribution of deposits.
