How does a geologist define a fault
WebFault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust. Large areas of bedrock are broken up into blocks by faults. Blocks are characterized by relatively uniform lithology. The largest of these fault blocks are called crustal blocks.

http://eqseis.geosc.psu.edu/cammon/HTML/Classes/IntroQuakes/Notes/faults.html WebA fault is a crack in Earth’s crust. An intrusion is a body of igneous rock formed within Earth’s crust. When two features intersect, the one that cuts through the other is younger. This is known as the law of crosscutting relationships. Some strata contain index fossils, or fossils associated with a specific time in Earth’s history.
WebJul 20, 1998 · 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 … WebEarthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on reverse or thrust faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. The fault surface can be vertical, horizontal, or at some …
WebA fault is boundary between two bodies of rock along which there has been relative motion (Figure 12.4d). As we discussed in Chapter 11, an earthquake involves the sliding of one body of rock past another. Earthquakes don’t necessarily happen on existing faults, but once an earthquake takes place a fault will exist in the rock at that location. In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults.

WebA fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other.
