The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
Fault line hanging wall.
Hanging wall and footwall.
Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall.
This type of faulting occurs in response to extension.
Usgs in these faults which are also caused by compression the rock of the hanging wall is actually pushed up.
The fault plane in a reverse fault is also nearly vertical but the hanging wall pushes up and the footwall pushes down.
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.
It is the inclination of the fault plane that is vertical.
The line it makes on the earth s surface is the fault trace.
The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments.
These are often found in intensely deformed.
A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source.
When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.
It is a flat surface that may be vertical or sloping.
Offset dispersal splays relay or tri shear termination.
The hanging wall moves up and over the footwall.
Thrust faults are reverse faults that dip less than 45.
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.
A dip slip fault in which the upper block above the fault plane moves up and over the.
The block below is called the footwall.
The upper block or in other words the block above the fault plane is called hanging wall.
Fault plane is called the hanging wall or headwall.
The fault plane is where the action is.
If the motion was down the fault is called a normal fault if the movement was up the.
The block below the fault plane or in other words beneath the fault plane is called the footwall.
This terminology comes from mining.
The hanging wall occurs above the fault plane and the footwall occurs below it.
Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust.
We distinguish between dip slip and strike slip hanging wall movements.
This sort of fault forms where a plate is being compressed.
