Diapir Model Structural Restoration
The background image is of a cross-sectional scale model simulating normal faulting over the crest of an active diapir . The preparation for restoration involves the following steps:
- Drawing of fault traces
- Drawing of horizon segments - ensuring that individual horizon segments do not cross faults, and that horizon segments on either side of a fault project neatly into the fault so that slip on the fault can be determined.
- Selection of horizon for "one-click" restoration.
The instantly restored structural configuration corresponds very well with the observed intermediate state of development of the model (see Nunns (1991)), particularly in the upper part of the section. There are a few complications at the bottom of the section due to artifacts associated with fault terminations.
Example from Nunns(1991).
