Forms: 1900s– plancheite, 1900s– planchéite.

Origin: A borrowing from French. Etymon: French planchéite.

Etymology: < French planchéite (A. Lacroix 1908, in Compt. rend. hebd. de l'Acad. des Sci. 146 724) < the name of J. Planche , French traveller and naturalist, who brought the first specimens of the mineral from the Congo + -ite -ite suffix¹.

Mineralogy.

1968 Mineral. Abstr. 19 54/1 Planchéite occurs in the iron deposit of Capo Calamita, Elba, where it was found in the form of small masses with a radial fibrous structure, associated with dioptase and chrysocolla.

1977 Amer. Mineralogist 62 491/1 Unfortunately, for planchéite the poor quality of the asbestos-like material has allowed only a semi-quantitative structure refinement.
