Department of Earth and Space Sciences, University of California, Los Angeles The unifying theme in this section is the remarkable weakness of major faults. I will consider the diverse new evidence for weakness, and the evidence for high pore pressure localized in faults as a fundamental cause. With this background one can better understand why faults remain active even after large rotations with

Recognition of fault bend fold, detachment and decapitation has been possible despite the poor quality of the seismic. That was successful because of: A full integration of all disciplines including reservoir engineering petrophysics and geochemistry Vizualization in 3-D that made all members of the team speak the same language

We will now approach the function A(a) from an entirely different point of view, i.e.,we will interpret the S-fabric in terms of strain1. (1.) We assume that the initial fabric is defined by a random orientation of surface, i.e.,that the ODF of the surface is uniform;

STRIKE - The direction of the line formed by the intersection of a horizontal plane with a bedding or fault plane. DIP - The angle formed by the intersection of a bedding or fault plane and the horizontal plane. The angle is measured in a vertical plane perpendicular to the strike

构造地质学的研究对象和内容 构造地质学是地质学的一门分支学科,其研究对 象是地壳或岩石圈的构造 地质构造是指组成地壳的岩石、岩层和岩体在内,外动 力地质作用下发生的变形与变位,而形成的各种现象( 构造),诸如褶皱、断裂、劈理以及其它各种面、线状 构造等

一、了解地质剖面图的图饰要素 二、掌握地质剖面图的编制方法

第一节 地质年代与地层产状 第二节 褶皱构造 第三节 断裂构造 第四节 地质图

就几何形态而论,任何构造都可看成是面状构造或线状构造 面状构造和线状构造都可以分成为“透入性”和“非透入性 ”两类。 透入性构造均匀地弥漫于地质体中的构造,反映地质体作 为一个整体,也均匀地发生了变形
