Fault (geology) - Wikipedia
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.
Fault | Definition & Types | Britannica
2024年12月11日 · 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 on the opposite sides of the fracture.
What is a fault and what are the different types? | U.S ...
What is a fault and what are the different types? A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
Fault and Types of Faults » Geology Science
2023年11月28日 · Faults are geological features characterized by fractures or zones of weakness in the Earth’s crust, along which movement has occurred. These fractures can vary in size and scale, and their characteristics provide valuable information about the history and dynamics of the Earth’s crust. Here are some key characteristics of faults:
Fault (geology) - Simple English Wikipedia, the free encyclopedia
A fault is a fracture, or break, in the Earth's crust (lithosphere). Some faults are active. Here, sections of rock move past each other. This sometimes makes earthquakes. Faulting occurs when shear stress on a rock overcomes the forces which hold it …
1.11: Faults - Geosciences LibreTexts
A fault is a planar geologic structure. Like any planar structure, it has an orientation that may be characterized by strike and dip. For small faults, it may be possible to walk up to an outcrop and measure the orientation with a clinometer.
9.5: Faults - Geosciences LibreTexts
Faults are the places in the crust where brittle deformation occurs as two blocks of rocks move relative to one another. Normal and reverse faults display vertical, also known as dip-slip, motion. Dip-slip motion consists of relative up-and-down movement along a dipping fault between two blocks, the hanging wall, and footwall.

2024年5月16日 · Faulting. A fault is a boundary between two bodies of rock along which there has been relative motion (e.g., Figure 13.23). Some large faults, like the San Andreas fault in California or the Tintina fault, extending from northern British Columbia through central Yukon and into Alaska, show evidence of hundreds of kilometres of motion.
Fault (geology) - New World Encyclopedia
In geology, a fault (or fault line) is a planar rock fracture that shows evidence of relative movement. Given that faults do not usually consist of a single, clean fracture, the term fault zone is used when referring to the zone of complex deformation associated with the fault plane.

2017年10月16日 · 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 movement. Not every crack in the ground is a fault. What defines a fault is the movement of the rock on either side.
