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
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
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;
