About Adranosite-(Fe)
Formula:
(NH4)4NaFe3+2(SO4)4Cl(OH)2
Alternative crystal-chemical formula, emphasising the presence of -Na-Cl-Na-Cl- chains in the structure:(NH4)4Fe3+ 2(OH)2(SO4)4.NaCl; some NH4 may be replaced by K.
Colour:
pale yellow
Lustre:
Vitreous
Specific Gravity:
2.18
Crystal System:
Tetragonal
Name:
For the relation to Adranosite-(Al).
Type Locality:
Isostructural with:
The Fe3+ analogue of Adranosite-(Al). Chemically related to acmonidesite and therasiasite.
Originally described as an anthropogenic phase that has formed on a burning coal dump ["Unnamed (NH4-Fe-Na-Cl Sulphate)"]. Subsequently found in a natural fumarole.
Structurally, an unusual salt inclusion phase (Kolitsch & Brandstätter, 2007; Mitolo et al., 2013).
In the crystal structure, beside the NaCl chains, there are:
- helicoidal [FeO4(OH)2SO4]n chains
- NaO4Cl2 square tetragonal bipyramids that share Cl-bearing corners
- NH4+ ions are located in cages, and the ammonium-bearing sites have the coordination number 9.
Synonymous with UM2011-17-SOCl:FeHNNa.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.

Interference Figure:
This shows the idealized uniaxial interference figure - the conoscopic
(convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis
centred and vertical. The coloured rings are isochromatics, computed with the
same physics as the Michel-Lévy bar above; the dark cross is the isogyre.
For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.
