地堑

汾渭地堑南段平均P轴直立，显示张性构造运动。

The vertical mean P axis in the southern part of Fen-Wei Graben indicates tensional tectonic movement there .

铁法盆地属于晚中生代的NNE向半地堑煤盆地，北西西系是其主要的成盆期构造。

Tiefa basin is a late Mesozoic NNE-trending half graben coal-bearing basin , and the NWW structural system is the most important synbasinal structure .

阜新盆地属于晚中生代NNE向地堑式煤盆地。

The Fuxin basin is a late Mesozoic NNE-trending graben coal-bearing basin .

进入新生代后，形成了一个受NNE、NE向断层控制的半地堑式复合盆地，叠置于中生代盆地之上。

And it was a half-graben composite basin controlled by NNE and NE faults and superposed on the Mesozoic basin .

中白垩世孙宗湾组的沉陷进一步向东侧移，形成了以F1断层为盆缘断层的半地堑；

The subsidence of Sunjiawan episode in Middle Cretaceous are further transferred eastward , and the half-graben defined by the fault F1 was formed .

后者受控于NW-SE向的拉伸应力场，形成了由NE向的断裂系统控制的半地堑式断陷盆地。

While the latter was controlled by NW-SE trending extensional tectonic stress field , forming half graben bounded by NE trending fault system .

地堑的走向一般为N60°E左右，相对于冲绳海槽的走向更偏向于东西方向，偏角在15°左右。各段中央地堑是被NW向断裂错开的。

The striking direction of central graben is N60 ° E roughly , that is 15 ° more to the east comparing to the striking of the Okinawa Trough .

那是在2000年3月份，我和我的朋友保罗（Paul）正在位于巴拿马-哥伦比亚边界的达连地堑（DariénGap）寻找稀有植物物种。两位哥伦比亚导游刚刚带我们进入一片林间空地。

It was March 2000 and I was with my friend Paul in the Dari é n Gap on the Panamanian-Colombian border looking for rare plant species . We had just entered a clearing with our two Colombian guides .

超层序Ⅲ由F（T5-Tg）层序组构成，为盆地初始发育阶段扭张构造应力产生的地堑内形成的层序，分布局限，其体系域展布特征不明。

Supersequence ⅲ consists of sequence member F ( T_5-T_g ) distributed in grabens or half-grabens and formed by transtensional stress during the initial stage of the basin developing . Its spread area is smaller and its tract patterns are riot clear .

东部地区速度变化以低速异常为主：①整个华北和东北地区，都呈现Pn低速异常，特别是华北盆地区、渤海湾和山西地堑低速异常非常明显，最小低于7.8km/s；

The whole North-China and most northeastern China have low velocities , especially in North-China basin , Bohai bay and Shanxi rift valley , the velocities are abnormally low . The lowest velocity reaches 7.8km/s .
