Apart from the amphibolite enclaves and dyke swarms, the isotopic ages of the magmatic intrusions have been measured. The magmatic sequence and geochronologic framework are as follows: Quartz monzonite, 1825 ± 23 Ma, TDM = 2920Ma; Throndhjemite, 2374 ± 10 Ma, TDM = 3460 Ma; Tonalite, 2604±102 Ma, TDM = 3063 Ma; Monzonite, 3096±17 Ma, TDM = 2978 Ma; Granite, 3605±43 Ma, TDM = 3528 Ma.

The Huashan—Guposhan granitoid belt consists of Tong'an, Huashan, Niumiao, Jinziling, Wuyangshan, Lisong and Guposhan granitoid bodies. Petrographycally, they are diorite, quartz monzonite, monzonitic granite and syenogranite. Dark mafic enclaves are very common. Their major emplacement ages are 160~163 Ma.

Calidonian granites are widely developed in the Yema Nanshan area in the western segment of the Qilian orogenic belt. The geochemical characteristics of most of the granites are similar to those of adakites: SiO2≥56%, Al2O3≥15.0%, low MgO (average 2.04%), high Sr (257-889μg/g, average 546.42μg/g), low Y (7.1-25.3μg/g,average 16.67μg/g), average Sr/Y=5.89, no pronounced Eu anomaly and Sr positive anomaly. Adakites in this area have five rock types, quartz diorite, quartz monzodiorite, quartz monzonite, monzogrannite and hornblende granite. These rocks commonly contain hornblende, belonging to I-type granites.
提要:祁连西段野马南山一带发育大量的加里东期花岗岩,其中大部分花岗岩具有与adakite岩相似的地球化学特征,SiO2≥56%, Al2O3≥15.0%,低MgO(平均2.04%),高Sr(257~889μg/g,平均值546.42μg/g),低Y(7.1~25.3μg/g,平均16.67μg/g),Sr/Y平均为35.89μg/g,Eu无明显负异常,Sr正异常,Adakite岩石类型有石英闪长岩、石英二长闪长岩、石英二长岩、角闪花岗岩、二长花岗岩,岩石中普遍含有角闪石,属I型花岗岩,地球化学图解反映该花岗岩形成环境为板块碰撞前的岛弧型,锆石U-Pb同位素年龄为444+38/-33 Ma,处在祁连造山带板块俯冲收缩阶段,因此可以推断野马南山埃达克质Adakite花岗岩是俯冲板片部分融熔和壳幔岩浆混合形成的。
