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

Structural Geology- Introduction Introduction Structural geology is the study of deformed rocks, and rock deformation. In structural geology, we are faced with a series of natural features that we try to interpret and explain. Each of these features formed through the interplay of external forces on rock materials, and the \local \conditions at the time of deformation. To interpret structures in the natural setting we need to

岩石圈板块的碰撞、拼贴等板块间的相互作用，在板块边缘具有明确的显示， 形成诸多造山带。而相对刚性板块的内部对于板块相互作用的反映与表现、板 内变形对于板块运动的调节作用等是人们尚未完全认识的一个重要方面。板块 内部应力场的分布
