| Sinkankasite is very rare at the Palermo Mine.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1.2 to 1.5 mm white, bladed, sprays on vivianite.
Field Collected: Forrest Fogg
Catalog No.: u2020
Notes: Ex. Mike Swanson collection. Acquired by Ray Meyers and donated to the NH Mineral display. The specimen boxes with original labeling are included here.
A tiny blade fragment was extracted for EDS analysis from the sinkankasite spray shown in the top photo (at about the 8 o'clock position). The semi-quantitative EDS analysis gave a result consistent with sinkankasite (within the limitations we have experienced with this instrument for carbon tape mounted grains.) Two probings were made and the element atomic percents measured were converted to atoms per formula unit (APFU).
