Journal Article
Published: 01 February 2009
The Canadian Mineralogist (2009) 47 (1): 25–38.
...William G. Mumme; Dan Topa; Emil Makovicky Abstract The crystal structure of proudite was redetermined with the holotype material from Tennant Creek, Australia, using a Nonius single-crystal diffractometer and Mo K α radiation. Our determination of the structure, based on 3388 observed reflections...
