first grade structure
Examples
- The northern qaidam basin is one of the structure cells in the qaidam basin where located in qingzang plat . ,
柴达木北缘块断带为柴达木盆地一级构造单元，面积约3万km ~ 2 。 - While there is no distict evidence to prove the tanlu fault ' s noted deep and dynamic behavior within the lower crust or even on the upper mantle . thus there still exists a necessary to research and check the understanding about the boundary ' s location and the dynamic background
作为一级构造单元分界线的红河断裂、怒江断裂是超壳断裂，而昌宁双江断裂显示为低角度铲式断层，中下地壳无与之对应的速度异常，可能意味着该断裂切割不深。 - Based on an integrated analysis of the surface geological , aeromagnetic , gravity , mt and seismic data from the area of mangnai to serteng mountains in the western qaidam basin , the authors think that the qaidam basin is sandwiched between the north kunlun block and serteng tectonic belt , including two first - order tectonic units the qaidam block and the southern margin of the qilian block and four second - order tectonic units the northern margin of the north kunlun block , qaidam basin , serteng tectonic belt and suhai lake basin in the south of the qilian block
摘要通过柴达木盆地西部茫崖赛什腾山地表地质、航磁、重力、大地电磁测深和地震资料的综合分析，认为柴达木盆地夹持在昆北地块与赛什腾构造带之间，其中包括柴达木地块与祁连地块南缘2个一级构造单元和昆北地体北缘，柴达木盆地，赛什腾构造带和祁连地块南部的苏干湖盆地等4个二级构造单元。 - According to the distribution of the fracture zones and the surface layers , the dazhaigou - haizigou valley can be divided into two first - grade and three second - grade tectonic areas , which greatly affect the landform pattern and surface material movement , and thus influence profoundly the formation and growth of debris flow
根据区内断层展布格局和地层出露情况将该区分为两个一级构造区和三个二级构造区，这三个构造区制约着地貌格局和地表物质迁移，进而对泥石流的形成和发展产生深刻影响。
