摘要
扬子地台西缘的海相火山岩归纳为５种组合１７种构造一岩石亚组合。其中最佳含矿组合为细碧角斑岩组合、玄武－流纹岩双峰组合和均一玄武岩组合等。铜多金属矿床的产出及规模受火山岩建造特征、火山岩时代和碱度，以及火山喷发旋回和古火山机构等联合控制。
The marine volcanic rocks in the western edge of the Yangtze platform can be classified into five combinations,17 structure-rock subcombinations, in which the Spilite-keratophyre combination,bimodel combination of basalt-rhyolite and homogeneous basalt combination etc. are the best rock combinations for mineralization. Copper polymetallic deposits, their distribution and scale were unitedly controlled by the volcanic formation, age and alkalinity,as well as volcanic eruption cycle and paleovolcanic apparatus etc.
