Abstract
The principal cause of 18O depletion, Ca2+ increases, and Mg2+ decreases in the pore fluids of cores from leg 35 of the Deep Sea Drilling Project (DSDP) is the alteration of basalt, volcanic ash, and igneous components of terrigenous material. Post-depositional diagenetic reactions have produced smectites, zeolites, K-feldspar, and celadonite as the main authigenic products. 18O/16O data from calcite and clay minerals suggest that these reactions took place over a range of times, temperatures (10–60 °C), and pore fluid 18O/16O compositions. At site 323, the sediments 30–74 m above basement are enriched in Mn, Fe, Cu, Ni, Co, Mo and Sr. Below these horizons, Ba shows a sharp increase towards basement. The 13C/12C values (δ = −18.4 to −21.2‰ PDB) of authigenic calcites in the sediments reflect an organic matter source for the carbon.
