A fault along which movement occurs as sediments are deposited on and above the fault scarp. Continued movement and sedimentation over an extended period of time causes the oldest and lowermost sediments to be offset the most and causes the amount of offset to decrease upward within younger deposits (fFigure1). Such faults are common in the Gulf Coast. | A fault along which movement occurs as sediments are deposited on and above the fault scarp.
