Hardcopy $10 . The Coal Oil Point fault is located approximately 4,000 feet south of the San Joaquin A fault is a planar discontinuity along which displacement of the rocks occurs. In the illustrated example, a fault surface is exposed in a ravine. A left-lateral strike-slip fault. CE 437: Structural Geology Notes 3 IV. Lecture Index: Notebook terms./ Description of idealized fault components./ Fault zone rocks and structures./ Fault recognition at map scale./ A traditional fault classification. Types of Strike-slip fault movement. Faults fracture = a discontinuity or break in rock fault = a discontinuity in which one block has slipped past another (Mode II or III) joint = a discontinuity in with no slip parallel to fractures some opening (Mode I) 1. The bedrock geology will be discussed only in generalities because it . The block that should be in the foreground has been eroded away. Slickenlines lying in a fault surface track the slip direction. All of the topics presented in Chapter 2 fall under the sphere of geology, and questions or problems in characterizing soils or The fault is located about 200 feet south of both Coal Oil Point and Goleta Point. Readings: Reading in Fossen, Structural Geology textbook, pages 119-126, and 135-138, 151-185 The contacts between different geologic formations The fault trends east-west and has resulted in at least 5,400 feet of vertical separation. Download PDF : Missouri Landscapes: A Tour Through Time, by John Hawker. Figure 3. Geologic maps show the distribution of the various igneous, sedimentary, and metamorphic rocks at Earth’s surface in plan view. Fault, in geology, a planar or gently curved fracture in the rocks of Earth’s crust, where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of the fracture. The geology student is standing where the foreground block was prior to erosion. GEOLOGIC MAPS . Reverse: rocks above the hanging wall moves up relative to the footwall Strike-slip: rocks on either side of a nearly vertical fault plane move 2019 Geotechnical Manual Page 2 of 15 is too complex and diverse to cover within the scope of this manual. • Fault zones and fault rocks • Types of faults and terminology • Slip vs. separation • Faults in wells • Fault propagation Terminology Hanging wall Foot wall Faults, fault zones, shear zones Fault Zone Shear Zone Fault zone geometry depends on mechanical stratigraphy (Richard et al., 2013) Fault Lecture notes are available as PDF files. Hanging wall – HW – block above fault plane 19 Normal: rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. Detailed mapping of the sea floor has revealed no surface expression of this fault. Descriptive geometry of faults A. Hardcopy $20 : Revised Recharge Areas of Selected Large Springs the Ozarks, by James W. Duley and Cecil Boswell . The relative position of the hanging wall and footwall (as discussed in GY 111 lectures) is also indicated on the diagram. You may need to install Acrobat Reader to obtain the PDF documents.
