About NatropharmacosideriteHide

Formula:
NaFe3+4(AsO4)3(OH)4 · 4H2O
Colour:
Light green, dull orange; pale green in transmitted light.
Lustre:
Vitreous
Hardness:
3
Specific Gravity:
2.79
Crystal System:
Isometric
Name:
The name reflects its dominant sodium content and relationship to pharmacosiderite. Originally name sodium-pharmacosiderite, the name was later changed to natropharmacosiderite (Nickel 2008).
Pharmacosiderite Group.
Forms a series with pharmacosiderite.

Initially found on a single museum specimen, presumably a weathering product of arsenopyrite.
