The tectonism in this area can be divided into three phases , that is the folded basement formation and stable ancient land in pre - mesozoic , ancient land cracking phase in mesozoic , the faulted activity and subsidence phase in cenozoic 本区构造变动划分为三个大的阶段,即:前中生代褶皱基底的形成和稳定古陆发育阶段、中生代古陆裂解阶段、新生代块断活动及整体沉降阶段。
2 . doppler frequency shifting and curve fitting differential methods for measuring velocity are analyzed and compared . the least - squares curve fitting methods based on power functions and orthogonal functions are analyzed and compared 2 .对测量速度的两种方法,多普勒频移法和曲线拟合微分法作了分析和比较;对以幂函数族和以正交函数族为基底的最小二乘曲线拟合法作了对比分析。
Based on 1 : 100000 high - precision aeromagnetic data , the author holds that huangzhuguan - yushuba fault is not only a second - order synsedimentary fault associated with lixian - mayanhe regional fault in the north , but also a deep fault that cuts the basement 摘要通过对1 : 10万高精度航磁资料研究,认为黄渚关榆树坝断裂不仅仅是其北部礼县麻沿河区域性断裂伴生的1条次级同沉积断层,而是1条切割基底的深大断裂。
The tectonic framework and border faults of the basin were related to the basement configuration . 3 . based on the regional tectonic setting and sedimentary sequence evolution , the structural physics modeling and balance profile reversion are first carried out 焉耆盆地前中生代基底硬块的形态及内部结构对中新生代盆地的形成及形变具有重要的控制作用,现今盆地的构造格局和重要的边界断层都与基底的结构有关。
