interpreted thrust front, DW Namibia Interpretation

Interpretation of the thrust front in DW Namibia. The thicknesses of units either side of the thrust are essentially the same - no there is no evidence for different amounts of layer parallel shortening (or extensional) strain across the front - or for differential compaction (post displacement) across the thrust.
