摘　　要："小岩体成大矿"是根据我国岩浆硫化物矿床找矿勘探实践提出的独创性的理论,其核心就是现今被广泛研究的"岩浆通道系统成矿"。结合典型的矿床实例,系统分析总结了产于岩浆通道系统上小型含矿岩体的主要特征、小岩体形成超大型矿床的关键因素以及岩浆通道系统型矿床的找矿方向和标志,以期促进对该类型矿床的进一步研究。The theory of the large-scale mineralization occurring in small intrusion is based on mineral ex- ploration of magmatic sulfide deposit in China, and is an original principle of ore deposit. The key of this theory is similar to the formation of magmatic sulfide deposits in magma conduit system. In this paper, we attempt to summarize the general features and the key formation mechanism of the small intrusions of the magmatie sulfide deposits occurring on magmatie conduit system. We also try to estimate the prospecting direction and criteria of this type magmatic sulfide deposit. All of these are very significant to promote further researches and expIoration of this type of deposit.
