Normal Fault With Hanging Wall And Footwall

A downthrown block between two normal faults dipping towards each other is a graben.

Normal fault with hanging wall and footwall.

When the fault plane is vertical there is no hanging wall or footwall. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. Block position under the hanging wall. The hanging wall moves down relative to the foot wall.

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. The strike is the direction of the fault. A n fault forms when the hanging wall moves down relative to the footwall a. 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. In a normal fault the hanging wall moves downward relative to the footwall. The hanging wall moves down relative to the footwall. Normal faults occur in areas undergoing extension stretching.

Low angle normal faults with regional tectonic significance may be designated detachment faults. Normal fractures in rock with no offset where there has been no motion are called. Formed by compressional stress rocks are pushed towards each other thrust fault. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

After the occurrence of a normal dip slip fault in flat lying sedimentary rocks the fault scarp produced is eliminated by erosion. Any fault plane can be completely described with two measurements. 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. If the hanging wall drops relative to the footwall you have a normal fault.

Normal faults are common. In a normal dip slip fault which of the following statements describes the movement of the hanging wall relative to the footwall. The hanging wall moves up relative to the foot wall. Other articles where normal fault is discussed.
