Fault Types And Hanging Wall

Where the crust is being pulled apart normal faulting occurs in which the overlying hanging wall block moves down with respect to the lower foot wall block.

Fault types and hanging wall. 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 moves up and over the footwall. Depending upon the inclination of the fault number of types of faults are recognized. Normal faults are common.

Hanging wall and footwall. This type of faulting occurs in response to extension. The hanging wall slides down relative to the footwall. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.

A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source. This terminology comes from mining. Other articles where normal fault is discussed. Where the fault plane is sloping as with normal and reverse faults.

Thrust faults are reverse faults that dip less than 45. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. This sort of fault forms where a plate is being compressed. The hanging wall occurs above the fault plane and the footwall occurs below it.

The line it makes on the earth s surface is the fault trace. Where the crust is being compressed reverse faulting occurs in which the hanging wall block moves up and over the footwall block reverse slip on a gently inclined plane is referred to as thrust faulting. It is the horizontal displacement between the hanging wall and footwall. These are often found in intensely deformed.

Strike slip faults have a different type of movement than normal and reverse faults. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. When movement along a fault is the reverse of what you would expect with normal gravity we call them reverse faults. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

The two sides of a non vertical fault are known as the hanging wall and footwall. It is a flat surface that may be vertical or sloping. Occurs when the hanging wall moves down relative to the foot wall reverse fault. Usgs in these faults which are also caused by compression the rock of the hanging wall is actually pushed up.

The hanging wall will slide upwards right. A fault in which hanging wall hw has apparently come down with respect to the footwall fw is termed as normal fault. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. There are three or four primary fault types.

The fault plane is where the action is.
