Materials

	Name	Arrangement	Mass (g)	Mass fraction	Abundance comments
	Pyrrhotite sub-micrometer size grains			0.77	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 56 vol%.
	Ammonium sulfate			0.23	This abundance value is an upper 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 lower or equal to about 23 wt%. Volumetric abundance lower or equal to about 44 vol%.
