通过河北滦平盆地早白垩世16个采点95块样品的古地磁研究,获得其特征剩磁方向为:D=347.8°,I=50.4°,a_(95)=7.1°;相应的极位置为:经度=346.3°E,纬度=76.1°N,dp=6.4°,dm=9.5°,古纬度=31.1°.通过对比华北地块中鄂尔多斯盆地的早白垩世古地磁结果,表明滦平盆地自早白垩世以来相对于鄂尔多斯盆地发生了30.7°±9.8°的逆时针旋转,而纬度方向上没有明显的变化,这一构造旋转可能与区域断裂活动和构造滑脱,以及库拉-太平洋板块自早由垩世以来朝NNW-NWW方向的挤压,与中国东部大陆的碰撞有关.
Through the paleomagnetic study of 95 samples of 16 Early Cretaceous strata of Luanping Basin in Hebei Province, the remanent magnetization directions are obtained as follows: D = 347.8 °, I = 50.4 °, a_ (95) = 7.1 °. The corresponding pole position The results are as follows: longitude = 346.3 ° E, latitude = 76.1 ° N, dp = 6.4 °, dm = 9.5 ° and paleo-latitude = 31.1 ° .According to the paleomagnetic results of Early Cretaceous in Ordos Basin of North China Block, Since the Early Cretaceous, a counterclockwise rotation of 30.7 ° ± 9.8 ° occurred in the Ordos Basin with no obvious change in the latitudinal direction. This tectonic rotation may be related to the regional fault activity and tectonic slip, and the early period of the Kula-Pacific plate Since the Cretaceous toward the NNW-NWW direction of extrusion, and China's eastern continent collision.
