Comment:
AGE is the stratigraphic age (Rea et al., 1998, doi:10.1029/98PA00123) of the sample

| # | Name | Short Name | Unit | Principal Investigator | Method/Device | Comment |
|---|---|---|---|---|---|---|
| 1 | AGE | Age | ka BP | Geocode | ||
| 2 | Sample code/label | Sample label | Pettke, Thomas | DSDP/ODP/IODP sample designation | ||
| 3 | Sample mass | Samp m | g | Pettke, Thomas | ||
| 4 | Mineral assemblage | Min assembl | Pettke, Thomas | X-ray diffraction (XRD) | ||
| 5 | Potassium | K | % | Pettke, Thomas | Abundances based on the total volume of 39Ar and the age. The error on these estimates is of the order of 10-20%, resulting from the errors on the sample size and the volumes during step analyses | |
| 6 | Argon-39 | 39Ar | % | Pettke, Thomas | The break seal sample gas fraction (Dong et al., 1995 doi:10.1126/science.267.5196.355, Hall et al., 1997 doi:10.1016/S0012-821X(97)00041-1) permits the measurement of the recoil loss of Ar isotopes from the sample during irradiation | |
| 7 | Age model | Age model | ka | Pettke, Thomas | The encapsulated total gas age is equivalent to a conventional K-Ar age (Dong et al., 1995, Hall et al., 1997), it includes the recoil fraction of 39Ar | |
| 8 | Age, standard deviation | Age std dev | ± | Pettke, Thomas | Total gas age, 2-sigma error | |
| 9 | Age, standard deviation | Age std dev | ± | Pettke, Thomas | Retention age, 2-sigma error | |
| 10 | Age model, optional | Age model opt | ka | Pettke, Thomas | The retention age (Dong et al., 1995, Hall et al., 1997) is the integrated age of all steps without the 39Ar recoil fraction, hence is equivalent to conventional 40Ar/39Ar bulk melting ages |
