白扬河岩体为超浅成侵入岩(潜火山岩),形成时代晚石炭世-早二叠世,其中值位于早二叠世早期,年龄值为293±15 Ma。岩性为花岗斑岩。其空间展布严格受杨庄大断裂控制,岩体中有晚期北西向辉绿岩脉及闪长斑岩脉贯入。岩体呈近东西向展布,东西长约10 km,南北宽变化较大,最宽达1.8 km,最窄0.1km,面积约6.9 km2。岩体的侵入方向由南东向北西,在横断面上似镰刀形;其北部与泥盆系地层呈侵入接
The Baiyanghe pluton is an ultra-shallow intrusive rock (subvolcanic rock) that formed in the Late Carboniferous-Early Permian. The median value is located in the early Early Permian with an age of 293 ± 15 Ma. Lithology is granite porphyry. Its spatial distribution is strictly controlled by the Yangzhuangda fault, and there are late Northwest diabase diorites and diorite porphyries in the rock mass. The rock mass is nearly east-west distribution. The east-west length is about 10 km and its width varies greatly from north to south with the widest 1.8 km and the narrowest 0.1 km with an area of 6.9 km2. The intrusive direction of rock mass is from south to east to north and west, and resembles sickle in cross section. In the north, the Devonian strata invaded
