Section  and volume restoration is a powerful tool to understand and validate structural interpretations.  The idea is that if you can draw a section through a structure, you might understand it.  If you can balance that section (1. Use structures that you can observe  in the region is similar type structures or that you know occur in a particular structural domain and   2. You can restore the section to its undeformed state). 
Restoration of the section by increments provides kinematics and intermediate geometries as additional constraints on your interpretation. 

The section below was drawn through the Paradox Basin in western Colorado and eastern Utah in a NE (right end) to SW direction.  The Uncompaghre Uplift is shown on the right.  The Paradox Basin is unique in the Rocky Mountains because of its prominent salt walls and minibasins.  The Basin was not highly deformed by the Laramide Orogeny (Late K-Paleogene) and so shows salt tectonics 'frozen in time' approximately in the geometry that was present as they formed. 

The following sections show incremental restoration of the Paradox Basin.  The lines in the synorogenic Cutler Group represent reflectors on the seismic data that can be mapped with confidence in making the interpretation.  Only a few of the incremental steps are included here.

The section 1 is an interpretation of the Paradox Basin today
Section 2 shows the basin after restoration of some of the synorogenic deposits of the Early Permian Cutler Group.  The correlation of the synorogenics are known from mapping around the plunge ends of the salt walls.  Sections are restored using the "Last in, First out" method.  That is, the most recent sediments are removed from the section first.
Section 3. After removal of the Mesozoic section
Section 4. Removal of the assymetric sediment of the 'heel' of the youngest basin
Section 5.  Removal of the asymmetric sediment package of the 'toe' of the next youngest basin
Section 6. Removal of the asymmetric sediment package of the 'heel' that minibasin
Section 7.  Removal of both the 'toe' and 'heel' packages of the next youngest minibasin
Section 8.  Removal of part of the sediment of the oldest minibasin and some of the faulting at the front of the Uncompaghre Uplift that produced the geometry of the NE side of the basin.
Section 9. Removal of older parts of the sediment in this minibasin and restroration of the some more of the fault displacement.
Section 10.  Restoration of the Paradox Basin implies that when the Paradox Salt was deposited, the Uncompaghre Uplift was not yet present.  This has additional implications for the Late Paleozic tectonics of the region.  See Kluth and DuChene, 2009, Rocky Mountain Association of Geologists.
North-South structural cross section of the southern Owl Creek Mountains (trend E-W) in central Wyoming, based on well and seismic data. North is on the right. The section implies that the Owl Creek front is a thrust array that began as a triangle zone that then was 'abandoned' by the trusts that bound the core of the range made up of Precambrian basement rocks.  This section implies several miles of southward shortening across the front.
