Hanging Wall Block Moves Down Relative Footwall Block

Hanging wall block moves up relative to footwall block.

Hanging wall block moves down relative footwall block.

Reverse faults indicate compressive shortening of the crust. Normal faults are dip slip faults where the hanging wall block moves down relative to the footwall block and they occur when the crust is extended or lengthened. The hanging wall block and footwall block are labeled in the following diagram. When discussing movement along nonvertical faults the hanging wall occurs above the fault and the footwall occurs below the fault.

In thrust faulting. In a reverse fault the hanging wall block moves up relative to the footwall block. The hanging wall moves down relative to the foot wall. Fractures in rock with no offset where there has been no motion are called.

Normal faults are common. In a normal fault the hanging wall block moves down relative to the footwall block. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins of tectonic plates. Block position under the hanging wall.

In dip slip faults if the hanging wall block moves downward relative to the footwall read more. Strike slip faults are right lateral or left lateral depending on whether the block on the opposite side of the fault from an observer has moved to the right or left. The hanging wall moves up relative to the foot wall. Normal faults are caused by tensional stress.

Horizontal block motion. There are three main types of dip slip faults. Block position over the fault. In a n fault the hanging wall block moves up with the respect to the footwall block.

Fault forms when the hanging wall moves down relative to the footwall. Hanging wall block moves down relative to footwall block. When the hanging wall moves down in relative to the footwall it is called a fault. True the oldest sedimentary rock strata are exposed along the axial parts of deeply eroded anticlines.

When the hanging wall moves up in relative to the footwall it is called a fault. Vertical motion of fault blocks fault scarps. These usually occur when tectonic forces cause tension that pulls rocks apart. Rift valleys are formed by the sliding of the hanging walls downward many thousands of metres where they then become the valley floors.

The hanging wall slides down relative to the footwall. Formed by tensional stress rocks are stretched away from each other reverse fault. An upthrown block between two normal faults dipping away from each other is a horst. Low angle normal faults with regional tectonic significance may be designated detachment faults.

The crust is shortened and thickened.
