  1. 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

    巖石化學、微量元素、同位素地球化學證據都表明，華北、華南地區的火山巖根據源巖和局部熔融程度的不同，可以分為兩個原生巖漿系列：一個是源巖為尖晶石二輝橄欖巖，隨著局部熔融程度的增加，形成的碧玄巖巖漿-堿性玄武巖巖漿-橄欖拉斑玄武巖巖漿；另一個是源巖為石榴石二輝橄欖巖，隨著局部熔融程度的增加形成的霞石巖巖漿-堿性苦橄玄武巖系列。
