New Zealand Crustal Fault Structural Model Video Discussion Video Discussion Video Discussion This example illustrates how StructureSolver can be used to estimate the deep trajectory of crustal scale faults, using a relatively small amount of structural information from the cover section. Such determinations can be valuable when doing basin-scale analysis. By varying the fault trajectory you can also get an estimate of the uncertainties in your solution. Locking hangingwall cutoffs greatly simplifies this analysis. Otherwise you need to perform iterative adjustments of the deep fault trajectory and the hangingwall reference depths.
