华北克拉通北缘中段主要由变质的太古宙单塔子杂岩、古元古代红旗营子杂岩、未变质的大庙-长哨营等辉长岩-斜长岩-偏碱性花岗岩和晚古生代变质铁镁质到花岗质岩石组成。约2.49Ga的单塔子杂岩包括麻粒岩相到角闪岩相变质的闪长质-奥长花岗质-花岗闪长质-二长花岗质片麻岩,岩石化
The middle part of the northern margin of the North China Craton is mainly composed of the metamorphic Archean monolayer complex, the Paleoproterozoic Hongqiyingzi complex, the unmodified Daomei-Changming camp, the gabbro-plagioclase-alkaline granite and the late Paleozoic metamorphic iron magnesia to granitic rocks. The single-tangled complex of about 2.49 Ga consists of dioritic-amphibolite-granodiorite-monzonitic granitic gneiss with granulite-amphibolite facies metamorphism, lithification
