A geologic cross section should integrate all known borehole, geophysical, and surface data; information off the line of section should be projected along strike (along plunge in folded strata) into the section. A cross section that is balanced is not necessarily correct, but one that is not balanced is invariably wrong unless a valid explanation is provided in the cross section. Structural balancing not only produces a more accurate cross section, but it also tests the ideas that we build into the section.
To be balanced, a cross section should be drawn (1) without vertical exaggeration, and (2) parallel to the direction of maximum regional extension (perpendicular to the strike of normal faults). Constant cross-sectional area before and after deformation must be assumed unless strain data are obtainable from the actual rocks.

Structural and Depositional Styles of Gulf Coast Tertiary Continental Margins: Application to Hydrocarbon Exploration
The structure and genetic stratigraphy of the Gulf of Mexico continental margin are inextricably intertwined. As hydrocarbon exploration and exploitation advance into the deeply buried Tertiary basin fill, interpretation of the complex depositional and structural styles of the outer shelf and upper slope setting will increasingly challenge the interpreter. This publication provides a coherent summary of the key concepts, models, and tools that are needed to meet this exploration challenge, and includes chapters on: basic principles, submarine slope systems, models of growth faults, mechanics of diapir growth, petroleum traps, and techniques on analyzing normal faults and balancing cross sections with extended strata.
