The seismic reflection profile below is from the High Island South Addition area, GOM basin, [[distance::20 mi]] east of the East Breaks shelf-margin delta. It illustrates the vertical stacking of seven depositional sequences within a fault-bounded salt-withdrawal basin. Down arrows at the inflection point of each clinoform identify the top of the clinoform of each sequence. In general, each cycle consists of (1) a thick basinal package of relatively discontinuous, variable-amplitude, hummocky reflections that grade upward into (2) parallel, continuous, uniform amplitude reflections, overlain by (3) a prograding clinoform that downlaps the underlying facies. Each clinoform is interpreted as a shelf-margin delta prograding into this outer-shelf to upper-slope fault-bounded basin as shown by the presentday sea floor profile. The seven prograding clinoforms are mapped into a nearby well and are correlated with two-cycle charts ([[:file:sedimentary-basin-analysis_fig4-25.png|Figure 1]]). Cycle 1 of this figure correlates with the clinoform package of [[:file:sedimentary-basin-analysis_fig4-19.png|Figure 2]].
