Found Sept 2000. Analyzed (EDS). This is one of two specimens with kodamaite from a find of “abundant” varennesite. The other specimen ( [1] ), has been confirmed by CMN staff via PXRD and EPMA (WDS). At the time that this photo was made (Dec 2017), the pinkish flaky stuff (mostly on the left) was unidentified, so the photo concentrated on the sphalerite crystal. The pinkish flakes have now been identified as likely kodamaite by staff of the Canadian Museum of Nature. (“Likely”, because the description of kodamaite has not yet – Dec 2022 – been published.) Currently the only other photo of kodamaite on Mindat is the one shown in the link given above. So a new photo featuring the kodamaite might be more appropriate. But I no longer own this specimen, so this photo (and the “related” – same minID – photos) will have to do. This specimen was analyzed via “quick & dirty” EDS in Dec 2017. — Photo: Modris Baum · CC0
Kodamaite
Kodamaite is an IMA-recognized mineral species in the silicate class, with the chemical formula Na₃(Ca₅Na)Si₁₆O₃₆(OH)₄F₂·(14-x)H₂O (x ≈ 5).
It crystallizes in the triclinic crystal system (space group P-1). It is a member of the Gyrolite structural group.
IMA symbol Kod, IMA status: approved, named in 2019.
It is found associated with Distribution From the Poudrette Quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu, Montérégie, Québec, Canada.
