[[:file:sedimentary-basin-analysis_fig4-50.png|Figure 8]] is a block diagram of the depositional model for the ''Glob alt'' reservoir interval. The model shows a 40-50-mi-long (60-80 km) transport system from a shelf-edge delta basinward to the East Breaks 160-161 minibasin. Depositional water depths exceeded [[depth::1000 ft]] (320 m) (upper bathyal), suggesting transport was by gravity-flow processes. Sandstone deposition in the minibasin may have resulted from subtle variations of sea-floor topography, perhaps related to early salt withdrawal.<ref name=ch04r53>Kneller, B., 1995, Beyond the turbidite paradigm: Physical models for deposition of turbidites and their implications for reservoir prediction, ''in'' Hartley, A.
