Figure 25. A simplified model of accommodation. 1) For any given area, the accommodation is the volume available for deposited sediment. 2 and 3) With constant sediment supply, deposition will fill in the available accommodation starting closest to the source and building outward. 4) With lower sea level, accommodation space decreases and the carrying capacity (typically) increases causing the erosion where the accommodation can not hold the surplus sediment. 5 and 6) In a faulted region, the accommodation is more variable and will reflect in a varied preservation potential.
