Abstract

Language:

The mineral ‘oboyerite’, first described in 1979 from the Grand Central mine, Tombstone, Cochise County, Arizona, USA, has been re-examined. The type specimen from the Natural History Museum, London and a specimen from the Natural History Museum of Los Angeles County were analysed in this study. The discreditation of ‘oboyerite’ as a valid mineral species has been approved by the IMA−CNMNC (Proposal 19-D). Single-crystal X-ray diffraction (SXRD), powder X-ray diffraction (PXRD), electron probe microanalysis (EPMA) and scanning electron microscopy (SEM) were all employed to show that ‘oboyerite’ is formed of at least two distinct phases, including the lead-tellurium oxysalt minerals ottoite and plumbotellurite. During the course of the discreditation, plumbotellurite was confirmed to be identical to the synthetic compound α-Pb2+Te4+O3. Previously, in some mineralogical literature plumbotellurite was described as orthorhombic with no known crystal structure.
