| contents | Manganese nodules, micronodules, and crusts were encountered in surface sediments, and at depth, in 6 of the 10 sites drilled during DSDP Leg 29 south of New Zealand and Tasmania. Major concentrations of surface nodule pavements occur on and adjacent to the Campbell Plateau south of New Zealand, south of the Tasman Rise, and in the South Tasman Sea. These deposits are found on top of erosional unconformities, which span tens of millions of years and reflect scouring by strong bottom currents. Micronodules were also found at depth throughout most of these cores. Their occurrence apparently is dependent upon a number of environmental factors. |
