"WebA special type of reverse fault is a thrust fault. A thrust fault is a low angle reverse fault (the dip angle is less than 30o). Table 8.2 summarizes the characteristics of normal and reverse faults. Figure 8.30 The hanging wall block, at the top, has moved up relative to the foot wall block, at the bottom, resulting in a reverse fault. " - Normal vs thrust fault

Web5 de jul. de 2024 · If the orientation of the maximum stress aligns with the fault, the primary rupture mechanism will likely be strike-slip, and the fault plane is often close to vertical. Compressional stress usually results in reverse (or thrust) faults, where an overhanging fault scarp may form at the surface. Where the crust is being pulled apart, normal ... Web1 de ago. de 1995 · In this case, the dip of the normal faults, whose geometry becomes planar, decreases with increasing thrust dip. We suggest that this change in dip of normal faults depends upon the rotation of stress tensor axes along the pre-existing fault zone, where a drop in the friction coefficient is likely to occur; (c) reactivation occurs in brittle …
