太行山—大兴安岭东麓碱性侵入岩带纵贯华北地台和内蒙海西地槽褶皱系两个大地构造单元,又处于我国东部太行山—大兴安岭地壳厚度陡变带和重力异常高梯度带之东侧,受NNE向超壳深大断裂的控制。该带中碱性岩体有20多个,但出露面积较大、研究较多、具有代表性的有以下6个碱性岩体(由南到北):河南安林地区九龙山霞霓正长岩体、河北永年洪山辉石正长岩体、易县紫荆关石英正长岩体、北京雾灵山正长岩—石英正长岩体、内蒙扎鲁特旗巴尔哲碱性花岗岩体、黑龙江碾子山正长岩—碱性花岗岩体。
The alkaline intrusive rocks on the foot of the Taihang Mountains-Daxinganling Mountains run through two tectonic units of the North China Platform and the Hercynian Tectonic Crevasse in Inner Mongolia, and are also located in the eastern part of the Taihangshan-Daxinganling crust thickness steep change zone and the gravity anomaly high gradient zone, Controlled by the NNE to deep deep faults. There are more than 20 alkaline rocks in the belt, but the exposed area is larger and there are more studies. The following six alkaline rocks (from south to north) are typical: Xiaonian, Jiulongshan, Anlin, Henan Zhengchang granite, Hebei Yongnian Hongshan gabbro syenite, Yixian Zi Jingguan quartz syenite, Beijing Wuling Mountain syenite - quartz syenite, Inner Mongolia Zhalute Banner Barzhe basic granite, Heilongjiang Nianzishan Syenite - alkaline granite body.
