− | Deposition or erosion of sediments depends on the interaction of cycle phase and the creation of accommodation space. The sediments comprising a depositional sequence are deposited during falling, lowstand, rising, and highstand phases of a sea level cycle. Erosion, which forms a critical element of the boundaries of a depositional sequence, generally occurs during falling sea level and lowstands.<ref name=ch04r99 /> Within the basin depocenter, the sequence boundary consists of a conformity that correlates with the erosional unconformity along the basin margin. | + | Deposition or erosion of sediments depends on the interaction of cycle phase and the creation of accommodation space.
