| contents | Most of the sediments at Sites 819 through 821 are underconsolidated, likely the result of high sedimentation rates. Normally consolidated sediments appear at intervals of low sedimentation rate at Site 820. Overconsolidation occurs in the shallowest unit of Site 820, suggesting recent mass wasting, and at the deepest interval, which may define an older erosional surface. At Site 819 for the depth range of 0 to 400 m, porosity is correlated with percentage of mud and is inversely proportional to carbonate content. Mass accumulation rates in the upper 30 m above a major hiatus at Site 819 are fairly constant from 240 to 100 k.y., following a 50-k.y. period of slightly higher accumulation rates. The mass accumulation rate increases steadily from 100 k.y. to the present. |
