Abstract:
The entire suite of halogens was measured in the pore fluids of Hole 1033B and 1034B from Saanich Inlet: ODP Leg 169S. The fast sedimentation rates and large amount of organic carbon burial coupled with anoxia of the overlying waters promotes an advanced stage of diagenesis within the sediment column. Chloride interstitial water profiles suggest salinity variations within the waters of Saanich Inlet. Concentration profiles for iodide and bromide support the argument that they are produced through the degradation of organic matter. Although the concentration increases in I- and Br- indicate that these halides are not regenerated in similar proportions to marine organic matter, it appears that iodide and bromide are regenerated to similar degrees within the sediment column and in similar proportions to the sediment halide concentrations. Fluoride porewater values show a complicated pattern, most likely caused by secondary reactions involving complexation with Mg2+, carbonate fluorapatite precipitation, carbonate mineral diagenesis, and/or uptake into alumino-silicate minerals.
