Hanging Wall And Footwall Normal Fault

The hanging wall slides down relative to the footwall.

Hanging wall and footwall normal fault.

Which fault will see the hanging wall move down relative to the footwall. Any fault plane can be completely described with two measurements. When the fault plane is vertical there is no hanging wall or footwall. With compressional forces the hanging wall moves upward relative to the footwall.

Reverse faults occur in areas undergoing compression squishing. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. Low angle normal faults with regional tectonic significance may be designated detachment faults. If the hanging wall rises relative to the footwall you have a reverse fault.

What is a reverse fault. The hanging wall on the left slides down relative to the footwall. A downthrown block between two normal faults dipping towards each other is a graben. The hanging wall on the right slides down relative to the footwall.

They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. A type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50 o to 90 o groups of normal faults can produce horst and graben topography or a series of relatively high and low standing fault blocks as seen in areas where the crust is rifting or being pulled apart by plate tectonic activity. The strike is the direction of the fault. Normal fractures in rock with no offset where there has been no motion are called.

This type of fault is referred to as a fault. Other articles where normal fault is discussed. Normal faults are common. Two parallel normal faults form.

Are exactly the opposite of normal faults. A normal fault occurs when the hanging wall moves relative to the footwall. Where the fault plane is sloping as with normal and reverse faults the upper side is the hanging wall and the lower side is the footwall. Normal faults occur in areas undergoing extension stretching.

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. An upthrown block between two normal faults dipping away from each other is a horst. A n fault forms when the hanging wall moves down relative to the footwall a.
