Datasets
| number | title | Methods | variables analyzed | ||
|---|---|---|---|---|---|
| 1 | Major element compositions of the ALH carbonates by analyzed EPMA. The data numbers correspond to the location of XANES measurements | EMP, CALC | MnO, CO2, TOTAL, MgO, SiO2, FeO, Na2O, CaO, SO3, P2O5 | ||
Methods
| method name | laboratory | method comment | More details are available for the following variables | |
|---|---|---|---|---|
| CALCULATED | UNKNOWN | Concentration of C02was determined by calculations based on stoichiometry because it cannot be measured by EPMA. | ||
| ELECTRON MICROPROBE | TOKYO INSTITUTE OF TECHNOLOGY | JXA-8530F, JEOL. 15 kV accelerating voltage and a 20 nA of focused (1μm in diameter) electron beam. The standard ZAF correction was applied to all the analyzed spots. |
