Structural Geology

Structural Geology / 09A / Leighty / Physical Geology (GLG 101IN) This lecture is all about stress and strain - mainly the principle types of stress (tension, compression, and shear) and the various types of strain that occur as a result. We will cover how to identify and interpret different types of faults and folds, and as always, visit locations around the world that display these structures. 0:00 Structural Geology 1:07 Stress & strain 1:57 Grand Canyon South Rim 3:55 Namibia 4:54 Types of stress 6:20 Types of strain 7:36 Measuring structures 9:47 Faults 10:50 Resting Springs Pass 11:50 Dip-slip faults 13:32 Normal faults 14:45 Moab Fault 18:14 Graben & half-graben 21:02 Low-angle normal faults 21:21 Metamorphic core complexes 23:05 Reverse faults 24:11 Thrust faults 25:41 Strike-slip faults 26:52 Piqiang Fault 28:20 San Andreas Fault 30:02 Oblique-slip faults 30:21 Joints 30:56 Arches NP 32:38 Folds 33:03 Parts of a fold 33:38 Describing folds 36:15 Anticlines 37:19 Synclines 38:07 Plunging folds 39:04 Monoclines 39:39 Raplee Ridge 42:03 Structural domes 42:46 Black Hills 44:53 Structural basins 45:27 Fold summary 45:44 Outtro
