小岩体成（大）矿思想于1979年从大量找矿实践中提出，经历了长期的理论研究和指导找矿实践，新发现了一批大型-超大型矿床，由此获得了越来越多的学者接受。本文通过总结小岩体成（大）矿的概念、内涵、范畴，提出小岩体成大矿优越的成矿禀赋集中体现在“小、广、大、高、浅（潜）”的五字特征。将小岩体成（大）矿思想提升到小岩体成（大）矿的理论。通过大量的矿床成因研究后，提出了两类小岩体成（大）矿的成矿模式、成矿机制、成矿类型，其中镁铁质岩浆成矿表现为深部熔离（预富集）-脉动式贯入-终端岩浆房（尾部）聚集成矿，中酸性岩浆成矿表现为岩体头部成矿（气，液，矿质，流体头部成矿）与岩体前峰及外侧空间成矿。

The idea that most of the lager deposits were formed by smaller intrusion was first-ly proposed on the basis of much prospecting practice in 1979. Through a long term of theoreti-cal researches and guiding prospections,many large and super large deposits have been discovered, so the thought was accepted by more and more scholars. By summarizing the conception,connota-tion and category of the theory for large deposits formed by smaller intrusion,this paper pointed out that the five key features of this theory are“small,wide,large,high and shallow (potential)”. Through many studies on the ore genesis,we developed the idea of the large deposit formed by smaller intrusion into a theory,and presented metallogenic models,metallogenic mechanisms and metallogenic types for two kinds of large deposit formed by smaller intrusion. One kind is the depos-it formed by mafic magma which has experienced deep segregation (preconcentration) at first,then emplacement by pulses and finally concentration into a deposit in the terminal of magma chamber;the other kind is the deposit formed by intermediate-acidic magma,which is presented as mineral-ization at the head of intrusion (mineralization at the head of gas,liquid,mineral,fluid),and miner-alization in the front of intrusion and lateral space.
