Fault Types And Hanging Wall

It is a flat surface that may be vertical or sloping.

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. It is the horizontal displacement between the hanging wall and footwall. Thrust faults are reverse faults that dip less than 45. The line it makes on the earth s surface is the fault trace.

Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. Hanging wall and footwall. A dip slip fault in which the block above the fault has moved downward relative to the block below. The hanging wall slides down relative to the footwall.

Normal faults are common. Occurs when the hanging wall moves down relative to the foot wall reverse fault. This terminology comes from mining. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

A fault in which hanging wall hw has apparently come down with respect to the footwall fw is termed as normal fault. A thrust fault moves the same way as a reverse fault but at an angle of 45 degrees or less source. Other articles where normal fault is discussed. These are often found in intensely deformed.

The hanging wall moves up and over the footwall. There are three or four primary fault types. The fault plane in a reverse fault is also nearly vertical but the hanging wall pushes up and the footwall pushes down. Usgs in these faults which are also caused by compression the rock of the hanging wall is actually pushed up.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The fault plane is where the action is. When movement along a fault is the reverse of what you would expect with normal gravity we call them reverse faults. The two sides of a non vertical fault are known as the hanging wall and footwall.

This sort of fault forms where a plate is being compressed. 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. 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. The hanging wall occurs above the fault plane and the footwall occurs below it.

This type of faulting occurs in response to extension. You probably noticed that the blocks that move on either side of a reverse or normal fault slide up. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

Strike slip faults have a different type of movement than normal and reverse faults.
