Web8 de dez. de 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 … WebThe displacement distribution along normal and thrust faults is maximum at the fault cen-ter and dies out to the fault margins. The thickness of the fault gouge is direct function of total slip along the surface (fig. 17).
