Fault Line Hanging Wall

A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source.

Fault line hanging wall.

Hanging wall and footwall. The line it makes on the earth s surface is the fault trace. The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. It is the inclination of the fault plane that is vertical.

The fault strike is the direction of the line of intersection between the fault plane and earth s surface. Offset dispersal splays relay or tri shear termination. 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.

A dip slip fault in which the block above the fault has moved downward relative to the block below. Thrust faults are reverse faults that dip less than 45. This sort of fault forms where a plate is being compressed. The upper block or in other words the block above the fault plane is called hanging wall.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. If the motion was down the fault is called a normal fault if the movement was up the. 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 the fault plane or in other words beneath the fault plane is called the footwall. These are often found in intensely deformed. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments.

Hanging wall and footwall. This terminology comes from mining. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. Fault plane is called the hanging wall or headwall.

Hanging wall movement determines the geometric classification of faulting. The fault plane is where the action is. The block below is called the footwall. The hanging wall moves up and over the footwall.

Where the fault plane is sloping as with normal and reverse faults. It is a flat surface that may be vertical or sloping. The hanging wall occurs above the fault plane and the footwall occurs below it. 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.
