Aragonite: Mistaken Identities
The full results of the X-ray diffraction (XRD) analysis done for the Rocks & Minerals paper “Aragonite: Mistaken Identities” are shown below. The samples are listed alphabetically by country of origin, and more specific location information is listed where known. Sample numbers are those used internally by the A.E. Seaman Mineral Museum, and separately analyzed phases from single specimens are denoted by ‘early’ and ‘late’ (along with any other distinctions) where appropriate.
All samples were originally identified as aragonite and the identification indicated by the XRD analysis is listed under the ‘New ID’ column.
Some locality information could not be verified, and may have been copying errors from the original transcription of the handwritten labels. Suspect locality names are put in quotation marks.
Please note that these were analyzed as individual specimens and the study is not meant to imply that all specimens from a given locality are, or aren’t, aragonite.
