About HydrohetaeroliteHide

Formula:
ZnMn2O4 · H2O
Colour:
Dark brown to brownish black
Lustre:
Sub-Metallic
Hardness:
5 - 6
Specific Gravity:
4.64 - 4.93
Crystal System:
Tetragonal
Name:
Named in 1928 by Charles Palache allusion to the water content (HYDRO) and its relationship to hetaerolite. The material was originally described as hetaerolite by William E. Ford and W. M. Bradley in 1913.
Discredited in 2018 (Bosi et al.)
Isostructural with:
Reinvestigation with modern methods seems desirable.
Unit-cell parameter c appears to be distinctly smaller than that of hetaerolite.

First Recorded Occurrence of HydrohetaeroliteHide

General Appearance of First Recorded Material:
Fibers grouped in radiated masses with botryoidal serfaces, also in massive granular and bladed aggregates that may be encrusted with chalcophanite
Geological Setting of First Recorded Material:
Late stage mineralization of a marble-hosted zinc oxide and zinc silicate ore deposit. Thought to be the result of advanced alteration of franklinite.
