Material
- Name
- Pyrrhotite sub-micrometer size grains
- Origin
- commercial
- Relevance
- main - major
- Mass fraction
- 0.77
- Abundance comments
- This abundance value is a lower value, because some amount of ammonium salt (but probably very little) may have sublimated with the water ice during preparation of this sublimate residue. Massic abundance superior or equal to about 77 wt%. Volumetric abundance equal or superior to about 52 vol%.
- Size method
- The natural sample of pyrrhotite was grinded as described in Rousseau et al. (2018) to form sub-micrometer size grains as confirmed by Scanning Electron Microscopy images.
