- Groundwater
Warm fluid (50 to 60 C) from 3.5 Ma basaltic basement, sampled from the casing of ODP Hole 1026B (Leg 168) two years after drilling (Sharma et al., 2000). Coordinates not published.

| 0.11 | 1 | low-temperature basement fluid Single analysis (ODP 1026B). ODP 1026B: 50 °C, Mg 2.42 mmol/kg, Cl 555 (556) mmol/kg, Os 518 fmol/kg, measured 0.111, corrected 0.11 ± 0.001. Cl in brackets: content corrected for seawater contamination during sampling. Os 518 fmol/kg and 187Os/188Os 0.110, below MORB (about 0.125): sign of an anciently depleted mantle domain beneath the ridge according to the authors. | Sharma et al.
