Fault Line Hanging Wall

We distinguish between dip slip and strike slip hanging wall movements.

Fault line hanging wall.

Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. 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. The block below is called the footwall. Usgs in these faults which are also caused by compression the rock of the hanging wall is actually pushed up.

Hanging wall and footwall. If the motion was down the fault is called a normal fault if the movement was up the. The fault strike is the direction of the line of intersection between the fault plane and earth s surface. This sort of fault forms where a plate is being compressed.

Hanging wall movement determines the geometric classification of faulting. Offset dispersal splays relay or tri shear termination. The block below the fault plane or in other words beneath the fault plane is called the footwall. The hanging wall occurs above the fault plane and the footwall occurs below it.

Occurs when the hanging wall moves down relative to the foot wall reverse fault. The upper block or in other words the block above the fault plane is called hanging wall. The fault plane in a reverse fault is also nearly vertical but the hanging wall pushes up and the footwall pushes down. A dip slip fault in which the block above the fault has moved downward relative to the block below.

The line it makes on the earth s surface is the fault trace. These are often found in intensely deformed. The fault plane is where the action is. A dip slip fault in which the upper block above the fault plane moves up and over the.

The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. This terminology comes from mining. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. Hanging wall and footwall.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The hanging wall moves up and over the footwall. Fault plane is called the hanging wall or headwall. It is the inclination of the fault plane that is vertical.

The two sides of a non vertical fault are known as the hanging wall and footwall. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. Thrust faults are reverse faults that dip less than 45. A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source.
