Where sedimentation rates are high, grounding-line fans and morainal banks can aggrade to sea level and form ice-contact deltas (Figure 7(a); Powell, 1990).Such deltas often form isolated flat-topped mounds, located on topographic highs that acted as pinning points during glacier retreat (Figure 7(b)).They are characterized by steep ice-contact slopes and pitted surfaces due to the melt-out of ...

SEDIMENTATION

The constant rate period corresponds to pulp settling at its initial concentration. During the final falling rate section the pulp is in compression. Point C is known as the compression point or the critical sedimentation point, and identifies the point at which the pulp-supernatant interface goes from zone settling into compression.
