If lower Tertiary Wilcox equivalent or uppermost Jurassic mudstones are the source for hydrocarbons in the East Breaks 160-161 field, then a migration avenue must exist through the salt that underlies the minibasin and [[Petroleum generation|generation]]-[[migration]]-[[accumulation]] must have been delayed until the trap formed approximately 1.2 Ma. In fact, alternative interpretations of salt distribution at the East Breaks 160-161 field suggest a salt weld with sediment-on-sediment below the minibasin rather than a salt floor (compare [[:file:sedimentary-basin-analysis_fig4-8.png|Figures 1]] and [[:file:sedimentary-basin-analysis_fig4-9.png|3]]). This suggests migration could have occurred from even older, more deeply buried source rocks.
