What type of fault is hanging?
Geology
Asked by: Mike Bruce
Reverse dip-slip faults result from horizontal compressional forces caused by a shortening, or contraction, of Earth’s crust. The hanging wall moves up and over the footwall. Thrust faults are reverse faults that dip less than 45°.
What kind of fault is a hanging wall?
normal fault
There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.
Is a hanging wall a normal fault?
Strike-slip faults are vertical and thus do not have hanging walls or footwalls. If the hanging wall drops relative to the footwall, you have a normal fault. Normal faults occur in areas undergoing extension (stretching).
What type of fault in which the hanging wall moves down?
Normal faults
Normal faults form when the hanging wall moves down relative to the footwall.
What is an example of normal fault?
An example of a normal fault is the infamous San Andreas Fault in California. The opposite is a reverse fault, in which the hanging wall moves up instead of down. A normal fault is a result of the earth’s crust spreading apart.
What is the example of reverse fault?
A reverse fault is called a thrust fault if the dip of the fault plane is small. Other names: thrust fault, reverse-slip fault or compressional fault. Examples: Rocky Mountains, Himalayas.
What are the 3 main types of faults?
There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip.
What are the 3 types of earthquake faults?
Three types of faults
- Strike-slip faults indicate rocks are sliding past each other horizontally, with little to no vertical movement. …
- Normal faults create space. …
- Reverse faults, also called thrust faults, slide one block of crust on top of another. …

In which type of fault is the hanging wall above the footwall quizlet?
in a reverse fault, the hanging wall moves up, or the footwall moves down, or both. reverse faults form when rock is under compression. stress that pushes rock together.
What is a strike-slip fault caused by?
Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. The fault motion of a strike-slip fault is caused by shearing forces. If the block on the far side of the fault moves to the left, as shown in this animation, the fault is called left-lateral.
What is reverse dip-slip fault?
reverse (thrust) fault – a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan.
Where is a strike-slip fault located?
3 Basic Fault Types:Normal, Reverse, Strikeslip (educational …
Which type of fault is describe by a hanging wall slipping down the football?
Normal dip-slip faults are produced by vertical compression as Earth’s crust lengthens. The hanging wall slides down relative to the footwall. Normal faults are common; they bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins of tectonic plates.
What is a hanging wall and footwall?
ore body is called the hanging wall, and rock located below the ore body is called the footwall.
What’s a hanging wall?
Definition of hanging wall
: the upper or overhanging wall of an inclined vein, fault, or other geologic structure —opposed to footwall.
In which type of fault is the hanging wall above the footwall quizlet?
in a reverse fault, the hanging wall moves up, or the footwall moves down, or both. reverse faults form when rock is under compression. stress that pushes rock together.
What type of fault is shown in the image below in this fault the hanging wall has moved up relative to the footwall?
In a reverse fault, the hanging wall slips UP the slope of the fault, i.e., the hanging wall moves up relative to the footwall.
What type of fault occurs when the hanging wall moves down relative to the footwall quizlet?
In a reverse fault, the hanging wall moves down and the footwall moves up. c.
