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。

The geological and geophysical data show that in the lower crust of young continental tectonic units may occur pervasive, non-seismic, subhorizontal and ductile flow related to thermal softening. The laminar flow drives fault-block movement of the upper crust, results in the formation of orogenic belts and sedimentary basins, and causes coupling between ductile lower crust and brittle upper crust/mantle.

大量的地质和地球物理资料表明，年轻的大陆构造活动区的下地壳可能因热软化而出现透入性非地震式顺层韧性流动，这种下地壳层流作用驱动大陆上地壳发生地震式脆性断块运动，形成盆山格局，发生圈层耦合。

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.

利用地震、钻井、测井等资料，将古近系沙河街组划分出7个三级层序，通过剖面沉积学分析，以优势相原则绘制不同时期各亚段沉积体系平面分布图：沙四下总体以洪水-漫湖沉积为特征，沙四上沉积时期是在滨浅湖背景之上发育了曲流河三角洲和辫状河三角洲沉积；沙三段沉积时期南部主要发育辫状河、曲流河三角洲，西北部地区发育曲流河三角洲，中部地区主要为深湖—半深湖沉积；由沙三下至沙三上，西北部三角洲规模逐渐增大，沉积范围逐渐向东、东南方向推进；沙二段沉积时期为滨浅湖沉积，在背景之上广泛发育了辫状河三角洲和三角洲沉积；沙一段以滨浅湖滩坝沉积为特征，南部发育了曲流河三角洲和辫状河三角洲沉积；沉积地层中的岩性圈闭以滑塌浊积岩岩性圈闭和地层侧向尖灭型岩性圈闭为主，其形成和分布主要受盆地结构、沉积古地貌和构造活动强度等因素控制，北部基山、南部江家店和瓦屋具有发育滑塌浊积扇的良好地质条件。
