About KhaidarkaniteHide

Formula:

Cu₄Al₃(OH)₁₄F₃ · 2H₂O

Originally given as Na_0.34Cu₄Al₃(OH)₁₄F₃ · 2H₂O.

Colour:

Light blue or bright sky-blue

Lustre:

Vitreous

Hardness:

2½

Specific Gravity:

2.84

Crystal System:

Monoclinic

Member of:

Cyanotrichite Group

Name:

Named after the discovery locality.

Type Locality:

ⓘ Khaidarkan Sb-Hg deposit, Kadamjay District, Batken Region, Kyrgyzstan

Cyanotrichite Group.
Visually similar to cyanotrichite and carbonatecyantrichite.

A small amount of sulphate may be present (or even necessary) in khaidarkanite; the Na content may be variable (Hager et al., 2009). Hager et al. (2009) attributed the Na content to impurities. The current (2022) IMA formula has no Na.
