Abstract:
Particles of red brown to yellow brown semiopaque oxides (RSO) dominate the insoluble residue fraction of the sediments at Site 597. Unlike the X-ray amorphous particles in the Bauer Deep sediments, these particles are composed of mainly goethite; the amount of X-ray amorphous ferric hydroxide and poorly crystalline ferromanganese oxyhydroxides is generally small relative to the amount of goethite.
A qualitative goethite crystallinity index was established. The variations observed in the crystallinity of goethite with increasing depth and changes in lithology suggest that aging and long-term exposure to seawater in a high water/sediment regime influence and increase the rate of recrystallization of the Fe-oxyhydroxides of the RSO particles.
The percentage of organic carbon is low in these sediments; it varies primarily between 0.2 and 0.4 wt.%. Phillipsite is present throughout the sediment column and is more concentrated in the youngest clay layer and in the oldest basal sediments.
