The Paleoproterozoic Beidahe Group-complex remains as continental shivers in the interior of the North Qilian orogen. In its early stage of development, there occurred abundant amphibolite. The protolith of the amphibolite is basalts. The Alk-∑FeO-MgO plot, REE features and Rittmann index show that the protolith belongs to the calc-alkaline suite and exceptionally shows the subalkaline character. The rock is characterized by higher Al2O3 and ∑FeO and lower Mg#, indicating that it has a higher degree of compositional evolution and that the formation of volcanic rocks is related to activation of older crust. Highly fractionated REE patterns and amphibolite on the Ti-Zr-Y plot, Ni-FeO/MgO plot and Ta/Yb-Th/Yb plot all indicate the characteristics of volcanic arcs and active continental margins. On the geochemical diagram of basalt, the overall REE features are in the main analogous to those of calc-alkaline island-arc basalt, with Sr87/Sr86=0.71617–0.72033,Nd143/Nd144=0.512414–0.512495 and εNd=–2.79 to –4.37,εSr=245.78–305.3, showing that the magma was derived from the crust or subjected to contamination with the lower crust below the continent.

提要：以大陆碎块形式残存于北祁连造山带内部的古元古代北大河岩群早期发育有大量的斜长角闪岩，其原岩为玄武岩，Alk—∑FeO—MgO图解，REE特征，里特曼组合指数等均显示斜长角闪岩属钙碱性系列范围，个别显示弱碱性，斜长角闪岩具有较高的Al2O3，∑FeO和低的Mg#，这些特点反映其成分演化程度较高，表明火山岩的形成与古老地壳的活化有关，有较强分异的稀土元素分配模式，在Ti—Zr—Y图，Ni—FeO/MgO图解和Ta/Yb—Th/Yb图解上斜长角闪岩均显示火山弧或活动大陆边缘的特点，在玄武岩的地球化学形式图，稀土元素整体特征与钙碱性岛弧玄武岩基本相同；87Sr/86Sr=0.716 17～0.720 33， 143Nd/144Nd=0.512 414～0.512 495，εNd=-2.79～-4.37。
