A material that is NOT an approved mineral species
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe-Mg-Ni-O-H
Crystal System:
Trigonal
Possibly a carbonate. Distinct from desautelsite and pyroaurite; Ni replaces Mn.
From Cedar Hill serpentinite quarry, Lancaster County, Pennsylvania, USA.
The structure is possibly composed of 1/4(Ni,Fe)OOH within the laminae of a Mg(OH)2 rhombohedral lattice.
