View of Doso Doyabi, Snake Range, Nevada, which was formed by detachment faulting. A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics . [ 1 ] Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic ...
Another example is the HúsavíkâFlatey fault. This oceanic transform fault is nearly completely submerged, but ~10 km is exposed in northern Iceland, near the town of Húsavík. There, it manifests as a series of half-grabens and sharp fault scarps. Since oceanic transform faults are often difficult to research because of their submerged ...
Schematic illustration of the two strike-slip fault types. The view is of the Earth's surface from above. In geology, the terms sinistral and dextral refer to the horizontal component of the movement of blocks on either side of a fault or the sense of movement within a shear zone. These are terms of relative direction, as the movement of the ...
Types of faulting. Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3] Movement of rock along the fracture occurs in faults.
Topographic map showing detachment folds in the eastern Sichuan Basin, China.. A detachment fold, in geology, occurs as layer parallel thrusting along a decollement (or detachment) develops without upward propagation of a fault; the accommodation of the strain produced by continued displacement along the underlying thrust results in the folding of the overlying rock units.
Biological illustration is the use of technical illustration to visually communicate the structure and specific details of biological subjects of study. This can be used to demonstrate anatomy , explain biological functions or interactions, direct surgical procedures, distinguish species, and other applications.
