Interstitial water studies on small core samples, legs 16, 17, and 18
Abstract
Legs 16, 17, and 18 encountered three groups of sediment types: rapidly deposited biogenic deposits, showing marked changes in interstitial calcium, magnesium, and strontium; slowly deposited biogenic deposits, showing little variability in pore fluids other than elevated silica concentrations; and terrigenous deposits. The latter showed the usual loss of sulfate and combination of diagenetic reactions culminating in loss of Na + , K + , Mg ++ , with variable changes in Ca ++ . Very high barium concentrations (to 59 mg/kg) occurred at Site 178 (Leg 18).
