On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.
岩石化学、微量元素、同位素地球化学证据都表明,华北、华南地区的火山岩根据源岩和局部熔融程度的不同,可以分为两个原生岩浆系列:一个是源岩为尖晶石二辉橄榄岩,随着局部熔融程度的增加,形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆;另一个是源岩为石榴石二辉橄榄岩,随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。
