Abstract:

This study of the interstitial water concentration-depth distributions of iodide, bromide, boron, d11B, and dissolved organic carbon, as represented by absorbance at 325 nm (yellow substance: YS) and laser-induced fluorescence (LIF), is a follow-up of the extensive shipboard program of interstitial water analysis during ODP Leg 131. Most of the components studied are associated with processes involving the diagenesis of organic matter in these sediments.

Three zones of the sediment column are discussed separately because of the different processes involved in causing concentration changes:

1. The upper few hundreds of meters: In this zone, characterized by very high sedimentation rates (>1200 m/m.y.), interstitial waters show very sharp increases in alkalinity, ammonia, iodide, bromide, YS, and LIF, mainly as a result of the diagenesis of organic carbon;

2. Whereas below 200 mbsf concentration gradients all show a decreasing trend, the zone at ~ 365 mbsf is characterized by concentration reversals, mainly due to the recent emplacement of deeper sediments above this depth as a result of thrust-faulting;

3. The décollement zone (945-964 mbsf) is characterized by concentration anomalies in various constituents (bromide, boron, d11B, manganese, LIF). These data are interpreted as resulting from an advective input of fluids along the zone of décollement as recent as ~ 200 ka. Possibly periodic inputs of anomalous fluids still seem to occur along this décollement zone.
