About Jianshuiite
Formula:
(Mg,Mn,Ca)Mn3O7 · 3H2O
Colour:
Brown to brownish-black.
Hardness:
1½ - 2
Crystal System:
Trigonal
Member of:
Name:
Named in 1992 by G. Yan, S. Zhang, M. Zhao, J. Ding, D. Li for Jianshui county which includes the type locality.
Isostructural with:
In the structure Mg is in the interlayer space, above and below the vacant sites of the Mn-O octahedral sheet. Mg has octahedral coordination, being linked to 3 oxygen atoms of the octahedral layer and 3 ones belonging to interlayer-residing water. Some Ni and maybe Mn2+ may be located at the Mg site.
