Supplement to: Gieskes, Joris M; Sirocky, Frank X; LaKind, Judy (1983): Interstitial water studies, Leg 72. In: Barker, PF; Carlson, RL; Johnson, DA; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 72, 391-394, https://doi.org/10.2973/dsdp.proc.72.109.1983
Interstitial waters collected at Sites 515 and 516 during DSDP Leg 72 have been analyzed for major and minor constituents. At both sites increases in dissolved calcium and decreases in dissolved magnesium with depth imply reactions in the sediment column involving these constituents. It is suggested that these concentration changes are related to reactions involving biogenic silica transformation.
