    摘要:

    与花岗质火山岩具不同的成因类型相似,自然界也存在着不同成因类型的次火山岩。后者与三大成因类型花岗岩相对应,亦可分为壳型次火山岩,过渡型次火山岩和幔型次火山岩三类。亮型次火山岩主要与U、REE,W、Sn、Nb、Ta等矿产有关系,属花岗岩矿床系列。过渡型次火山岩主要与Cu、Pb、Zn、Ag、Au有关,并伴有W、Sn成矿、属斑岩矿床系列。幔型次火山岩主要与黄铁矿型Cu、Pb、Zn多金属矿化有关,属海相火山岩矿床系列。

    Abstract:

    There occur different genetic types of granitic subvolcanie rocks in nature as well as different genetic types of volcanic rocks. Corresponding to three genetic types of granites, granitic subvolcanic rocks may be divided into three types: the crust, the transitional and the mantle-type. Subvolcanic rocks of the crust type related to U, REE, W, Sn, Nb and Ta mineralization belong to the series of ore-bearing granites. Subvolcanic rocks of the transitional type related to Cu, Pb, Zn, Au,Ag and associated with W and Sn mineralization belong to the series of ore-bearing porphyry. Subvolcanic rocks of the mantle type related to Cu, Pb and Zn multi-metal mineralization of the pyrite type belong to the series of ore-bearing volcanic rocks of the marine facies.
