正断层

首先，运用反射波地震勘探和电测深确定构造关系由原F13逆冲断层调整为F13正断层；

Firstly , reflected wave seismic exploration and electrical depth sounding were used to found that the original F13 thrust fault was in fact F13 normal fault ;

MCT1原为向南逆冲的韧性断层，后遭受北北东向褶皱作用而转变为正断层。

The MCT1 was originally a south-vergent ductile thrust , which was later transformed into a normal fault after it underwent NNE-trending folding .

在此之后，高原的应力体制转变为EW向伸展，在重力作用下形成了一系列SN向塌陷构造&裂谷和正断层。

Hereafter , the stress regime of the plateau changed into EW-striking extention and a series of SN-striking collapse structures formed under gravity effect .

昌平－丰南断裂已断到中更新世地层（Q2），为倾向SW的左旋走滑正断层。

The Changping Fengnan fault is a SW dipping sinistral slip normal fault , which dissects the middle Pleistocene ( Q 2 ) strata .

在Beryl湾发育南北向、北西向和北东向三组正断层。

Three sets of normal faults , with N-S , NW-SE and NE-SW orientations , have been recognized in the Beryl Embayment .

F17是拉伸作用下的同沉积正断层，切断煤系基底T3地层。

F1 , F2 and F17 are extended synsedimentary normal faults , which cut the T3 coal measures basement strata .

据推测，浅部正断层下方有一条高倾角地壳深断裂带，该断裂带向下断至Moho面，向上断至上地壳下部低速层中。

A high angle fault is explained to locate under the shallow normal faults which extend downwards into the Moho interface and upwards into the low-velocity layer .

并指出豫西断块构造中的NE、NW向高角度正断层经历了先剪后张的两次活动。

The author shows that the high-angle normal faults trending in NE and NW directions in the block faulted structure of Western Henan were subjected to the process containing shearing and tension successively .

珠江口盆地东部和台湾西部海域广泛分布的海相中生界发育3个方向的4种断层：NE向逆断层、NE向正断层、WNW&EW向正断层和NW向左行平移断层。

Four types of faults trending in three directions have developed in marine Mesozoic of the eastern Pearl River Mouth basin and offshore western Taiwan , including NE ? trending reverse faults , NE ? trending normal faults , WNW-EW ?

对于造成环绕浅成侵入岩体分布的18O亏损环带的流体的流动几何学，以及浅部正断层流体流动的几何学，耦合模型提供了不同于单一同位素交换模型的解释。

This complex model provides alternative interpretations for the geometry of flow responsible for the development of 18O depletion annuli surrounding epizonal intrusions and for the geometry of flow in shallow - level normal faults .

在构造形式上，早更新世时期发育低倾角拆离断层；中更新世（0.8Ma）以来，以高角度正断层活动为主。

As to the tectonic types , the detachment fault with low angle was developed in the Early Pleistocene and the normal fault with high angle only after the mid-Pleistocene ( 0.8 Ma B.P. )

剖面图上1&4s之间的强反射对应于由一组正断层产生的沉积层变形，其中新河断裂为束鹿盆地和新河凸起之间的边界主断裂，它伸展到8km以下深处。

On the section , strong reflections in 1-4 s TWT correspond to the deformation of sedimentary layers produced by a set of normal faults , where Xinghe fault is the main boundary fault between Shulu basin and Xinghe uplift , and extends to 8 km deep .
