2.
Based on systematic structural interpretation with 3D seismic data and analysis on regional geology and drilling data, the fault system and tectonic style of the Yitong Graben are studied.
通过对三维地震资料进行系统的构造解析,结合区域地质和钻井资料的分析表明,伊通地堑的断层系统在平面上主要由近东西向的张性正断层和北东走向的张剪性断层组成,反映盆地具右旋走滑的应力体制;断层在演化序列上分为4个类型,与盆地的形成和演化之间存在良好的对应关系。
5) half-graben
半地堑

补充资料：地堑
| 地堑 graben 地壳中被两侧倾向相反的正（或逆）断层所界限而中间断盘下掉的槽形断块构造。是一种长条形的断陷盆地，纵向延伸可达数百千米 ；仅在一侧为断层所限的断陷称半地堑。若同时发育着一系列走向大致平行但倾向依次相反的正（或逆）断层时，则地堑与地垒相间排列形成盆岭构造。地堑的形成与地壳的水平拉伸作用有关，在背斜的轴部也常发育地堑。地堑常与沉积矿产，尤其是煤和油气藏等密切相关。有名的地堑有欧洲的莱因地堑、中国的汾渭地堑等。 |
