Differential loading of the mobile salt resulted in some syndepositional subsidence and accommodation of the ''Glob alt'' sand-prone [[isochron]] thick. The apparent thickening into the north-bounding [[growth fault]] is due to the maximum differential subsidence and isochron thickening being coincident with the fault trace of a much younger growth fault phase. Biostratigraphic calibration of the fault system indicates most, if not all, of the fault offset occurred during middle Pleistocene time, after the ''Trifarina rutila bioevent'' (= ''Ang B'') dated at 1.30 Ma ([[:file:sedimentary-basin-analysis_fig4-31.png|Figure 10]]). This is more than [[length::1.5 m]].y. after deposition of the ''Glob alt'' sands.
