How To Tell Difference Between Hanging Wall And Footwall

The footwall cataclasite exhibits higher averages of neutron porosity 7 6 and lower values of electric resistivity 232 ωm compared to the hanging wall phyllite 4 8 453 ωm.

How to tell difference between hanging wall and footwall.

This clear contrast between the hanging wall and footwall may account for the difference in maximum burial and structural variation. In a fault plane that dips 45 degrees the overlying rock unit is the hanging wall and the underlying rock unit is the footwall. An upthrown block between two normal faults. A downthrown block between two normal faults dipping towards each other is called a graben.

Normal fault geology a type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50o to 90o. Groups of normal faults can. In normal faulting the hanging wall moves. 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 names come about from the. 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.
