Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock.
Reverse fault hanging wall and footwall.
You probably noticed that the blocks that move on either side of a reverse or normal fault slide up or down along a dipping fault surface.
The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
The hanging wall will slide upwards right.
It is a flat surface that may be vertical or sloping.
Its also called a reverse fault because a normal fault has the foot wall going up and the hanging wall.
The fault plane is where the action is.
The names come about from the.
When movement along a fault is the reverse of what you would expect with normal gravity we call them reverse faults.
The reverse faults occur when the hanging wall works its way up the footwall.
The movement along the thrust fault is the foot wall goes down and the hanging wall goes up.
This is the result of tension built up.
The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.
2 1 volcanism is the process by which molten rock reaches the earth s surface in order to make new landforms.
Strike slip faults have a different type of movement than normal and reverse faults.
This is a landform made from volcanism.
If we hold the foot wall stationary where would the hanging wall go if we reversed gravity.
The line it makes on the earth s surface is the fault trace.
The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults.
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.
