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. WebA fault is a fracture, or break, in the Earth's crust ( lithosphere ). Some faults are active. Here, sections of rock move past each other. This sometimes makes earthquakes . …

In a reverse fault, the earth on ... WebThe fault forms a lateral seal, while overlying clay-rich cap rocks provide a transient top seal. Fractures in the damage zone to the fault compromise the sealing integrity of this top seal and enable vertical migration of fluids, preferentially around structurally complexities where the fracture network is most intense.
