A cross section with internally consistent geometry: Concepts
of balancing cross sections applies to all kinds of faulting and deformation,
but was first developed in thrust systems.
- Balance occurs when bed lengths and cross-sectional area
are equal in both deformed and undeformed state (except with volume loss due
to consolidation and dissolution
- Structures drawn on section should be those observed in
outcrop or limited to geologic structures expected in a particular
- Cross section must be able to be restored to undeformed
state. That is, removal of deformation should result in group of undeformed
sedimentary rocks with expectable geometry
- Line-length and area balancing
- Depth to detachment calculation--an outcome of area
- Fault displacement established
- Section may be correct
If it doesn't balance it can't be right.
If it balances the cross section a possibly correct, acceptable solution.
