How To Tell Difference Between Hanging Wall And Footwall

Low angle normal faults with regional tectonic significance may be designated detachment faults.

How to tell difference between hanging wall and footwall.

As nouns the difference between hangingwall and footwall is that hangingwall is while footwall is geology the section of rock that extends below a diagonal fault line the corresponding upper section being the hanging wall. In a non vertical fault where the fault plane dips the footwall is the section of the fault that lies under the fault while the hanging wall lies. Strike slip faults have walls that move sideways not up or down. In an ideal cirque the headwall is semicircular in plan view.

In a normal fault the hanging wall moves downward relative to the footwall. The forces creating these faults are lateral or horizontal carrying the sides past each other. An arcuate cliff called the headwall. In reverse thrust faulting the hanging wall moves upward in relation to the footwall.

In a non vertical fault where the fault plane dips the footwall is the section of the fault that lies under the fault while the hanging wall lies over the fault the names come about from the. Cirques tarns u shaped valleys arêtes and horns. That is the slip occurs along the strike not up or down the dip. 48 the footwall exhibits a general trend of higher porosity and lower resistivity compared to the hanging wall and the clear contrast between the hanging wall and footwall may account for the difference in maximum burial accumulation of strain and structural variation across the thrust.

This situation however is generally found only in cirques cut into flat plateaus. In a fault plane that dips 45 degrees the overlying rock unit is the hanging wall and the underlying rock unit is the footwall. Difference between hanging wall and footwall. Other articles where hanging wall is discussed.

In these faults the fault plane is usually vertical so there is no hanging wall or footwall. In normal faulting the hanging wall moves downwards in relation to the footwall. More common are headwalls angular in map view due to irregularities in height along.
