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.
How to distinguish between hanging wall and footwall.
Its strike and its dip.
In a fault plane that dips 45 degrees the overlying rock unit is the hanging wall and the underlying rock unit is the footwall.
When the fault plane is vertical there is no hanging wall or 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.
There is a hanging wall and a foot wall and the hanging wall moves downward andcauses it to look like a hill in a way.
Groups of normal faults can.
In normal faulting the hanging wall moves.
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.
The names come about from the.
Any fault plane can be completely described with two measurements.
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.
