摘　　要："红透山式"块状硫化物铜锌矿床的成矿作用主要出现在三个较大的火山喷发—沉积旋中,双峰式火山岩构成了"红透山式"矿床的含矿岩系。呈透镜状、扁豆状的火山碎屑岩的发现为研究该类矿床提供了较为直观的地质依据。稀散元素和硫同位素特征亦表明该类矿床为古火山机构控制的海底火山喷发—沉积矿床。总结归纳了火山作用与成矿的关系。The metallogeic processes of massive sulfide copper-zinc deposit of Hongtoushan type mainly occur in three relatively large volcanic eruption-sedimentary cycles. Volcanic rocks of two-peak type consists the ore-bearing rock series in the Hongtoushan-type deposit. The findings of lens and bean-like pyroclast provide intuitionistic geological evidence for the deposit study of this kind. The characteristics of rare earth elements and sulfur isotope also suggest that this kind of deposit is volcanic eruption-sedimentary deposit controlled by paleovolcanic mechanism at sea bottom. The correlation of volcanic processes with metallogeny is summarized in this paper.
