Deformation of Rocks

Deformation of Rocks. How Rocks Deform Brittle-Ductile Behavior Faulting and Folding. Stress and Strain. The keys to understanding any deformation are stress (the cause) and strain (the effect). Compression. Rocks are squeezed or compressed by forces directed toward one another.

Recognizing faults

Recognizing faults. Practice with thrust faults and normal faults. Why study faults?. Classification of faults: - each type of fault forms under different geologic conditions - so, if we can characterize the nature of the fault, we can conclude something about the geologic history.

Forces In The Earths Crust

Forces In The Earths Crust. Crust: the thin outermost layer of the earth. Continental crust is relatively thick and mostly very old. Oceanic crust is relatively thin and is always geologically very young. Forces In The Earths Crust. Forces In The Earths Crust.

Earth Crust Deformation

Earth Crust Deformation. Caused by stresses in the crust. Opposing forces. Creates Strike slip faults as one side of the fault slips past the other. (side swipe) Can occur at transform plate boundaries. Crust is not created or destroyed and there is no up or down movement.

Types of Faults

Types of Faults. Strike Slip Fault: Two layers of rock are shifted horizontally or parallel to the fault plane. . 1) "Hanging Wall "- The surface of block that is ontop of the plane of the fault. 2) "Footwall" - The surface or block that lies below the plane of the fault.
