阴山地区从东南到西北，依次划分为桑干麻粒岩区、集宁副变质岩区、乌拉山－大青山前缘构造区和色尔腾山岛弧过渡区。桑干麻粒岩区代表了中太古微古陆并经新太古强烈岩浆增生的太古地壳；集宁区代表基底之上新太古末期－古元古沉积盖层；乌拉山－大青山区是基底岩石构造剥露的前缘构造区；色尔腾山区主要由深部花岗岩和浅部绿岩构成的太古岛弧区，古元古时期北部古岛弧和南部古大陆碰撞汇聚，继后北东南面向伸展使阴山地区早前寒武纪岩石剥露。
The Yinshan area is divided into Sanggan granulite area, Jining anti-metamorphic area, Wulashan-Daqingshan frontal tectonic area and Sertengshan island arc transitional area from southeast to northwest. The Sanggan granulite area represents the Archean crust that was enriched by the Neo-Archean strong magmatic magma in the Miocene Microtung and the Neo-Late Archean sedimentary cover over the basement of the Jining area. The Wulashan-Daqingshan area is the basement The front tectonic zone where the rock structure was exposed; the Serteng mountain argillaceous Archean arc zone which is mainly composed of deep granite and shallow greenstone; the ancient island arc in the northern part of the Paleoproterozoic and the ancient continental continent in the southern part converge; Stretch to Yinshan area early Precambrian rocks exposed.
