Table T21. Estimates of major ion concentrations expected at the pore fluid anomaly observed at 500 m CSF. (See table notes.)
|
Formation fluid |
Expected value |
Observed value |
|
|---|---|---|---|
| Mg (mM) | 5 | 15 | 16 |
| Ca (mM) | 157 | 128 | 127 |
| Na (mM) | 298 | 334 | 315 |
| SO4 (mM) | 4 | 9.0 | 8.5 |
| Cl (mM) | 620 | 608 | 604 |
Notes: Formation fluid value estimated by interpolating the data from above and below the observed anomaly at 500 m CSF. Expected value assuming a 20% seawater component, based on the potassium data.
