By the single zircon U Pb dating method, the quartz syenite porphyny yielded an age of concordance (1 731±29)Ma, and the aegirine augite syenite and syenogebbro are dated upper cocordi...
应用单锆石U Pb法测定年龄，石英正长斑岩谐和年龄为( 1731± 2 9)Ma ，霓辉正长岩、正长辉长岩上交点年龄分别为( 1644± 14)Ma、( 1750± 65)Ma.1650～ 170 0Ma是碱性岩浆活动热构造事件的标志，石英正长斑岩被中元古代晚期的高山河组不整合覆盖，故以 1650～ 170 0Ma作为熊耳群的上限。1650～ 170 0Ma热构造事件是华北地块重大地质事件，有可能是进一步划分中元古代重要的年龄界限。

The uplifting belt is composed of metasandstone, marble, overlying thick stromatolite (Jinyanshan Group of Jixian System). Metamorphic rocks of 450Ma± occur in both south and north active margin. Post-collision bimodal volcanic rocks and A-type granite occur in the middle and the north side;(4) Apa-Mangya tectonic melange belt consists of ophiolite (including ultramafic rocks, gabbro, plagiogranite and basalt) and flysch and eclogite of late Ordovician.
隆起带为中元古界变砂岩、大理岩，上覆厚层叠层石灰岩，南北边缘有均为450Ma左右的变质岩，中部和北侧分布有碰撞后双峰式火山岩与碱性花岗岩；④阿帕—茫崖构造混杂岩带，由超镁铁质岩、辉长岩、斜长花岗岩、玄武岩等蛇绿岩残片与晚奥陶世复理石沉积和榴辉岩块组成。

Detailed geology- petrology-mineralogy study shows that late Triassic-early Jurassic granites can be divided into 4 groups: granodiorites, monzonitic-K syenogranites mainly, alkali feldspar-alkali granites and syenite, Middle Jurassic granites is composed of quartz diorites-granodiorites and monzonitic granites, the main rock type includes granodiorites and monzogranites; Early Cretaceous granites include alkali gabbro, alkali granites and granodiorites, and these rocks composed bimodal igneous rock group.
详细的地质-岩石矿物学研究表明，晚三叠-早侏罗世花岗岩可以划分成四种岩石组合，即花岗闪长岩组合、二长花岗岩—正长花岗岩组合、碱长花岗岩—碱性花岗岩组合和正长岩组合，其中以二长花岗岩—正长花岗岩组合为主；中侏罗世花岗岩由石英闪长岩-花岗闪长岩组合和二长花岗岩组合构成，岩石类型以花岗闪长岩和二长花岗岩为主；早白垩世出现了碱性辉长岩、碱性花岗岩和花岗闪长岩，构成双峰式火成岩组合。
