About KamchatkiteHide

Formula:
KCu3(SO4)2OCl
Colour:
Greenish-yellowish brown
Lustre:
Vitreous
Hardness:
Specific Gravity:
3.48
Crystal System:
Orthorhombic
Name:
For the Kamchatka peninsula, in which the type locality is situated.
The recent structure refinement is done by Siidra et al. (2016). The structure may be understood as an example of "host-guest" principle, and this is attributable to other Cu oxysulphate minerals.
