Volcanic rocks, characterized by huge phenocryst, multi-phenocryst, clastic phenocryst and corrosive phenocryst, developed with surging rhyolitic, plastic agglomerate and pseudo accumulation structure, showing intrusive contact with big phenocryst granite batholith and granite porphyry vein, demonstrates its plutonic attribution.
以大斑、多斑、富碎斑和熔蚀斑为特征，发育涌动流纹、塑性集块和假堆积等构造，并与时差很小的大斑花岗岩基、大斑花岗斑岩脉呈侵入接触关系的非层状火山岩，预示其成因为深成端元属性。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.
根据对火山岩地球化学特征的综合分析表明，玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物，而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果，不同旋回的玄武岩和流纹岩有不同的源区，为多次脉动分层部分熔融的产物。
