| Resumo |
Sediment cored within the Barbados subduction complex at Sites 541 and 542 are underconsolidated. Underconsolidation and changes in physical properties of the cored section can be related to excess pore water pressure that equals the lithostatic load at Site 542 and to major thrust faulting observed at Site 541. Apparently, the pore fluids within the subduction complex are absorbing the tectonic shock of underthrusting. Sediment sampled from the reference Site 543 on the adjacent Atlantic Plate are also underconsolidated. However, underconsolidation in Hole 543 is apparently due to the movement of excess nitrogen gas observed deeper in the hole. Excess gas was not observed at Sites 541 and 542. |
