About ZincobotryogenHide

Formula:
(Zn,Mg,Mn2+)Fe3+(SO4)2(OH) · 7H2O
Colour:
Bright orange-red
Lustre:
Vitreous, Greasy
Hardness:
Crystal System:
Monoclinic
Name:
The name is derived from its zinc content and similarity to botryogen.
The Zn analogue of botryogen. The higher hydrate counterpart of chaidamuite. Chemically similar to zincocopiapite and somehow to lishizhenite. A very rare secondary Zn-Fe(III) sulphate formed in the oxidation zone.

Orginally described as a new mineral by Kwang-chih et al. (1964) from Xitieshan Pb-Zn deposit, Da Qaidam Co., Haixi Autonomous Prefecture, Qinghai (Chinghai) Province, China. Thereafter considered as a mineral that needed reinvestigation. Finally approved by IMA in 2016 (IMA 2015-107).

Crystal structure details:
(1) chains of the [Fe3+(SO4)2(OH)(H2O)]2− composition, set || c
(2) chain-linked [MO(H2O)5] octahedra, where M = Zn, Mg
(3) also chain-linked but unshared water molecule
(4) 1+2+3 gives larger chain-forming [M2+Fe3+(SO4)2(OH)(H2O)6(H2O)] module
(5) hydrogen bonds play a role of an inter-chain module linkage
