WebMar 23, 2024 · Reverse Fault: In the field of geology, a reverse fault is a dip-slip fault in which the hanging wall moves upwards, relative to the footwall. The average dipping angle of a reverse fault ranges from 45 to 90 degrees. However, if less than 45 degrees, it becomes a “ thrust fault .”. Reverse faults are the opposite of normal faults. WebDec 8, 2008 · 2.3.6 Reverse and thrust faults. In a reverse or thrust fault, the hanging wall has moved up relative to the footwall. The distinction between a reverse fault and a thrust fault is that a reverse fault has a steeper dip, greater than 30 degrees. Reverse and thrust faults develop in sectors of the crust that are experiencing compression. Webstructure of faults. In fault. …fault plane is called the hanging wall, or headwall; the block below is called the footwall.
