A normal fault is a geological fault where the hanging wall has moved downward relative to the footwall due to extensional forces, typically associated with divergent plate boundaries. Normal faults can be observed in various geological settings, such as rift zones and areas undergoing tectonic stretching.
A normal fault is a type of fault in which lengthening, or extension, of a portion of Earth’s crust causes a block of rock above the fault to move downward relative to the block below. Normal faults are common and bound many of the mountain ranges of the world as well as many of the rift valleys found along the margins of divergent tectonic ...
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.
Normal Fault: In a normal fault, the hanging wall (the block of rock above the fault plane) moves downward relative to the footwall (the block of rock below the fault plane). Normal faults are common at divergent plate boundaries where the Earth’s crust is stretching.
Normal faults are created by tensional forces in the crust. Normal faults and tensional forces commonly occur at divergent plate boundaries, where the crust is being stretched by tensional stresses (see Chapter 2). Examples of normal faults in Utah are the Wasatch Fault, the Hurricane Fault, and other faults bounding the valleys in the Basin ...
normal fault - a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.
On normal faults, the hanging wall has moved down relative to the foot wall. These faults are generally steeply dipping, with a dip angle of 60° or greater. Low-angle normal faults have a dip …
There are different types of faults: reverse faults, strike-slip faults, oblique faults, and normal faults. In essence, faults are large cracks in the Earth's surface where parts of the crust move in relation to one another.
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. They range in length from a few centimeters to many hundreds of kilometers.
Normal, or Dip-slip, faults are inclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed a Reverse fault.
