Hanging Wall Footwall Fault

The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.

Hanging wall footwall fault.

The hanging wall moves downward relative to the footwall. Hanging wall definition the underside of the wall rock overlying a vein or bed of ore. It is a flat surface that may be vertical or sloping. These are often found in intensely deformed.

Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. If the hanging wall rises relative to the footwall you have a reverse fault. The dip of a reverse fault is relatively steep greater than 45. Thrust faults are reverse faults that dip less than 45.

The mass of rock underlying a mineral deposit in a mine. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. Alternatively such a fault can be called an extensional fault. The fault plane is where the action is.

Where the fault plane is sloping as with normal and reverse faults. Fault plane is called the hanging wall or headwall. Reverse faults indicate compressive shortening of the crust. The fault strike is the direction of the line of intersection between the fault plane and earth s surface.

The block below is called the footwall. The line it makes on the earth s surface is the fault trace. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common.

Footwall synonyms footwall pronunciation footwall translation english dictionary definition of footwall. A n fault forms when the hanging wall moves down relative to the footwall a. The hanging wall moves up and over the footwall. The mass of rock overlying a mineral deposit in a mine.

The underlying block of a fault having an inclined fault plane. Reverse faults occur in areas undergoing compression squishing.
