This movement may vary from a […] Types 4. Engineering Considerations. Field Evidence 5. • Former margin of Farallon and Pacific plates. * * * * * * Figure 10.15b: View of the Humboldt Range in Nevada, which is a horst bounded by normal faults. Earthquakes and faults ; Movements that produce earthquakes are usually associated with large fractures in Earth’s crust called faults. Title: Kinds of Faults Created Date: 2/21/2008 12:55:42 AM Document presentation format: On-screen Show Other titles: Arial Arial Black Times New Roman Wingdings Eras Demi ITC Glass Layers Kinds of Faults Faults Three Types of Faults Fault Terminology Hanging vs. 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. Definition of a Fault 2. • Thickening, uplift ,and tensional stress caused normal faults. Dip-Slip and Strike-Slip Faults Are the Most Common Types of Faults.

PowerPoint Presentation - Normal faults Author: Laurel Goodwin Last modified by: Laurel Goodwin Created Date: 2/13/2006 3:36:08 PM Document presentation format: On-screen Show Company: UW Madison - Geology and Geophysics Other titles Definition of a Fault: Faults are fractures along which movement of one block with respect to others has taken place. Structural Geology (3443) Ch. ADVERTISEMENTS: After reading this article you will learn about:- 1. Parts of a Fault 3. Major Fault Types Fault Block Horst and Graben • Decompression melting and high heat developed above a subducted rift zone. Faults separate two adjacent blocks of rock that have moved past each other because of induced stresses. “A Fault is a break or fracture b/w two blocks of rocks in response to stress.” This movement may occur rapidly, in the form of an earthquake or may occur slowly, in the form of creep. Today’s lecture Application exercise Announcements Information about the research assignment Faults and stress Announcements No field trip on this Thursday, but yes on October 21! All about geological faults, their terminology, geometry and classifications. The notion of localized movement leads to two genetically different classes of faults reflecting the two basic behaviors of rocks under stress: brittle and ductile. Also included are fault related folds and recognition of faults in the field. Effects 6. Definitions . Structural Geology: Deformation and Mountain Building * Figure 10.11a: Fault terminology.
