About Wallkilldellite-(Fe)Hide

Formula:
(Ca,Cu)4Fe2+6(AsO4,SiO4)4(OH,O)8 · 18H2O
Colour:
Brown to brownish yellow
Lustre:
Vitreous, Resinous
Hardness:
2 - 3
Crystal System:
Hexagonal
Isostructural with:
The Fe analogue of Wallkilldellite. Note: The Mn dominant member of the series is not called Wallkilldellite-(Mn). The suffix "-(Mn)" has been used in error. Compare Mitridatite Group.

Apparently closely related to Unnamed (Arseniosiderite-related mineral) (see Walenta, 2006).
