Cross-section restoration is a powerful tool for checking if interpreted fault and horizon geometries can be restored to valid pre-deformation states.  
Essentially footwall cutoffs should correspond to hangingwall cutoffs when deformation is restored, with no gaps or overlaps in the restoration. It provides a robust method of evaluating structural histories. 
Geosec software can address extensional and reverse faulting, folding, ductile deformation, halokinesis and the overprinting of several deformation events.

Section restoration allows:

• evaluation of the geometric validity of seismic interpretations and constraint to be placed on fault and horizon mapping

• illustration of timing and magnitude of major phases of basin formation and later modification

• assessment of the history of structural elements e.g. displacement histories for key faults

• evaluation of pre-rift structural and stratigraphic patterns
