The two sides of a non vertical fault are known as the hanging wall and footwall.
Fault line hanging wall.
This type of faulting occurs in response to extension.
The hanging wall occurs above the fault plane and the footwall occurs below it.
It is a flat surface that may be vertical or sloping.
Thrust faults are reverse faults that dip less than 45.
The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
We distinguish between dip slip and strike slip hanging wall movements.
The fault plane in a reverse fault is also nearly vertical but the hanging wall pushes up and the footwall pushes down.
The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall.
Where the fault plane is sloping as with normal and reverse faults.
Occurs when the hanging wall moves down relative to the foot wall reverse fault.
Hanging wall movement determines the geometric classification of faulting.
It is the inclination of the fault plane that is vertical.
This sort of fault forms where a plate is being compressed.
Hanging wall and footwall.
The fault plane is where the action is.
Usgs in these faults which are also caused by compression the rock of the hanging wall is actually pushed up.
A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source.
The block below is called the footwall.
A dip slip fault in which the upper block above the fault plane moves up and over the.
If the motion was down the fault is called a normal fault if the movement was up the.
A dip slip fault in which the block above the fault has moved downward relative to the block below.
This terminology comes from mining.
Fault plane is called the hanging wall or headwall.
The hanging wall moves up and over the footwall.
The upper block or in other words the block above the fault plane is called hanging wall.
Note the small normal faults that displace the sandstone in the hanging wall and bend sole into the flatlying detachment the sandstone layers inbetween these small normal faults have rotated clockwise in this view as this faulting occurred.
Offset dispersal splays relay or tri shear termination.
Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust.
When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.
These are often found in intensely deformed.
