“…Growth faults in south Louisiana originate locally as a basal décollement at the top of geopressured diapiric ridges or ductile folds (Bruce, 1973;Riggs et al, 1991;Xiao and Suppe, 1989;Bally et al, 1981;Shelton, 1984;Nelson, 1991). The association of growth faults to subsurface controls, specifically geopressure, is direct (Hart et al, 1995;Hunt et al, 1994;Hunt, 1990;Bruce, 1973), and it is not surprising that fluids and gases are expelled from such zones (Sassen et al, 1993;Freed and Peacor, 1989).…”
