Push-up blocks are topographic uplifts that localize on the geometric irregularities along strike-slip faults where fault segments form a compressive stepover or bend.
Push-up blocks are an integral part of intraplate and interplate strike-slip fault zones (e.g., Sylvester and Smith, 1976; Christie-Blick and Biddle, 1985; Sylvester, 1988) and are very important structures for hydrocarbon accumulations. They represent structural traps as en échelon anticlines in places combined with stratigraphic traps (Harding, 1974, 1990; McClay and Bonora, 2001). Many large strike-slip fault zones commonly have large-scale push-up blocks associated with overstepping and bending both in marine and terrestrial environments (e.g., Angelier et al., 2004...
