Hanging Wall Block Moves Down Relative Footwall Block

When the hanging wall moves up in relative to the footwall it is called a fault.

Hanging wall block moves down relative footwall block.

These usually occur when tectonic forces cause tension that pulls rocks apart. Hanging wall block moves down relative to footwall block. In a reverse fault the hanging wall block moves up relative to the footwall block. When the hanging wall moves down in relative to the footwall it is called a fault.

Fractures in rock with no offset where there has been no motion are called. In thrust faulting. Rift valleys are formed by the sliding of the hanging walls downward many thousands of metres where they then become the valley floors. Vertical motion of fault blocks fault scarps.

An upthrown block between two normal faults dipping away from each other is a horst. The crust is shortened and thickened. 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. Formed by compressional stress rocks are pushed towards.

Horizontal block motion. The hanging wall moves down relative to the foot wall. In dip slip faults if the hanging wall block moves downward relative to the footwall read more. Normal faults are common.

The hanging wall slides down relative to the footwall. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. In a n fault the hanging wall block moves up with the respect to the footwall block. The hanging wall moves up relative to the foot wall.

Normal faults are caused by tensional stress. The hanging wall block and footwall block are labeled in the following diagram. Fault forms when the hanging wall moves down relative to the footwall. True the oldest sedimentary rock strata are exposed along the axial parts of deeply eroded anticlines.

Formed by tensional stress rocks are stretched away from each other reverse fault. To the dip is called dip slip faulting. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins of tectonic plates. Low angle normal faults with regional tectonic significance may be designated detachment faults.

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. Reverse faults indicate compressive shortening of the crust. Hanging wall block moves up relative to footwall block. When discussing movement along nonvertical faults the hanging wall occurs above the fault and the footwall occurs below the fault.

There are three main types of dip slip faults.
