Footwall And Hanging Wall Normal Fault

If the hanging wall drops relative to the footwall you have a normal fault.

Footwall and hanging wall normal fault.

A downthrown block between two normal faults dipping towards each other is a graben. 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. Other articles where normal fault is discussed. Normal faults occur in areas undergoing extension stretching.

In this fault the hanging wall moves down relative to the footwall. The term footwall is derived from miners finding mineral deposits where inactive faults have been filled in with mineral deposits at their feet. Boundaries of metamorphic core complexes. Formed by tensional stress rocks are stretched away from each other reverse fault.

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 dip slip faults are produced by vertical compression as earth s crust lengthens. Basin and range region. Formed by compressional stress rocks are pushed towards each other thrust fault.

Its strike and its dip. The hanging wall slides down relative to the footwall. Low angle normal faults with regional tectonic significance may be designated detachment faults. Hanging wall up footwall down.

Footwall where miners find mineral deposits a normal fault will have a hanging wall and a footwall. Block position under the hanging wall. Edges of horsts and grabens. Hanging wall down footwall up.

Zones of crustal extension. When the fault plane is vertical there is no hanging wall or footwall. In a normal fault the hanging wall moves downward relative to the footwall. An upthrown block between two normal faults dipping away from each other is a horst.

There is a normal fault which happens at a divergent boundary.
