How Does The Hanging Wall Move In A Normal Fault

Click for more information and to order.

How does the hanging wall move in a normal fault. In a normal fault the hanging wall moves downward relative to the footwall. Normal faults occur in areas undergoing extension stretching. In a reverse fault the hanging wall moves upward relative to the foot wall. The hanging wall will slide upwards right.

A downward fold in a rock is called a. If you imagine undoing the motion of a normal fault you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault. Hanging wall is where the ore is eroding out of the rocks the hanging wall is the side of the fault above the fault plane where the ore deposit is located. Low angle normal faults with regional tectonic significance may be designated detachment faults.

Extensional forces those that pull the plates apart and gravity are the forces that create normal faults. They are most common at divergent boundaries. If the hanging wall drops relative to the footwall you have a normal fault. Where does uplift occur.

An upthrown block between two normal faults dipping away from each other is a horst. When movement along a fault is the reverse of what you would expect with normal gravity we call them reverse faults. When rocks are pushed together by compression hanging walls tend to push above the footwall. Strike slip faults have a different type of movement than normal and reverse faults.

They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. A forms when the block of land between two normal faults slide downward. Normal fault s are common. When the ore erodes off the hanging wall it falls down onto the ground of the footwall where the miners were standing.

The hanging wall slides down relative to the footwall. You probably noticed that the blocks that move on either side of a reverse or normal fault slide up or down along a dipping fault surface. A downthrown block between two normal faults dipping towards each other is a graben. Normal faults form when the hanging wall drops down in relation to the footwall.

In fault normal dip slip faults are produced by vertical compression as earth s crust lengthens. In a normal fault the hanging wall of the fault moves down relative to the foot wall. When rocks are pulled apart by tension hanging walls tend to slip below the footwall.
