Geological Features and Processes

The video explores structural geology, focusing on the Carolina Bays and their integration into geological frameworks. It discusses the book 'Processes in Structural Geology and Tectonics' by Ben van der Pluijm and Stephen Marshak, highlighting its insights into deformation regimes. The video explains frictional and plastic regimes, geological structures like cataclasite and mylonite, and various fault types. It proposes a cold plastic regime to account for the formation of Carolina Bays, emphasizing the role of water in plastic deformations.
