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

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。

The petrophysical properties of volcanic rock reservoirs in junggar basin are generally characterized by the following : the acidic lava and auto brecciated lava are the best, especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts

Distant effect of jurassic collisions of qiangtang terrane, lasa terrane and paleo - pacific land onto the eurasian land made east qinling - dabie mountains in a compressional circumstance for a long time, and suppressed its orogenic extension ; whereas, cretaceous late - collisional extension and appearance of west pacific trench - arc - basin system relieved east qinling - dabie mountains of external compression, instantly result in violent orogenic lithosphere delamination - extension and depressurized - calefactive melting, and consequently, led to the formation of large scale early cretaceous granitoids and intermediate - acidic volcanic rocks
