A fault trace is also the line commonly plotted on geologic maps to represent a fault.

Normal fault hanging wall movement.

Hanging wall movement determines the geometric classification of faulting. Other articles where normal fault is discussed. They are identified by the relative movement of the hanging wall and foot wall. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

Reverse faults form when the hanging wall moves up. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. Faults are classified according to the direction of relative movement along the fault. The hanging wall slides down relative to the footwall.

Together normal and reverse faults are called dip slip faults because the movement on them occurs along the dip direction either down or up respectively. They are common at convergent boundaries. The forces creating reverse faults are compressional pushing the sides together. Thrust faults with a very low angle of dip and a very large total displacement are called overthrusts or detachments.

In a normal fault the hanging wall moves downwards relative to the foot wall. Normal faults are common. They are caused by extensional tectonics. There are three or four primary fault types.

If the motion was down the fault is called a normal fault if the movement was up the. Thrust faults are reverse faults that dip less than 45. A downthrown block between two normal faults dipping towards each other is a graben. Faults showing vertical movement include tensional normal and compressional reverse faults.

Low angle normal faults with regional tectonic significance may be designated detachment faults. The hanging wall moves up and over the footwall. We distinguish between dip slip and strike slip hanging wall movements. These are often found in intensely deformed.

In this type of fault the hanging wall and footwall are pushed together and the hanging wall moves upward along the fault relative to the footwall. Economic minerals often grow along faults and these terms come from where a miner would stand and where they would hang their lantern. Faults are subdivided according to the movement of the two blocks. An upthrown block between two normal faults dipping away from each other is a horst.

This is literally the reverse of a normal fault. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. In a normal fault the hanging wall moves downward relative to the footwall. A dip slip fault in which the block above the fault has moved downward relative to the block.

Normal faults and reverse faults are dip slip faults they experience vertical movement in line with the dip of the fault. Tensional faults are produced through tension extension or pulling apart of the crust causing the hanging wall to move down relative to the footwall.
