Planerite
- Mauldin Mountain
- Montgomery County
- Arkansas
- U.S.A.
- 5.6 by 2.6 by 2.1 cm – Miniature specimen (fits into a 5 cm cube)
Planerite is hydrous aluminum phosphate; it is a cation deficient member of the turquoise group. Foord & Taggart (1998) used material from this locality to redefine the species. The mineral name honors Dimitrii Ivanovich Planer (1821-1882), mineralogist and Director of the Gumeshevsk copper mines, Russia, who originally discovered the mineral (Hermann, 1862).
Planerite here forms a rather continuous coverage of pale green crystals to 0.5 mm. The planerite crystals group into wart-like aggregates. This specimen was part of the Charles Trantham (1936-2020) estate.
