The pseudomalachite-ludjibaite-reichenbachite conundrum: OD description

Emil Makovicky
Published: 30 September 2019
The Canadian Mineralogist (2019) 57 (5): 571–581.
DOI: https://doi.org/10.3749/canmin.1900016
...Emil Makovicky Abstract Crystal structures of the three polymorphs of Cu 5 (PO 4 ) 2 (OH) 4 , namely pseudomalachite, ludjibaite, and reichenbachite, can be described as being composed of rods perpendicular to their crystal-chemical layering. Two different sorts of rods can be defined. Type 1 rods...
