REVISED CHEMICAL FORMULAE

A paper on the mineral vigrishinite has been recently published [Mineralogical Magazine, 82 (2018), 787–807] in which the ideal chemical formula of the mineral is given as NaZnTi4(Si2O7)2O3(OH)(H2O)4, with sodium as an essential constituent. These data were examined carefully by the CNMNC officers and were considered reliable. Accordingly it was agreed to modify the formula of vigrishinite in the official IMA List of Minerals.

A paper on the mineral cafarsite has been recently published [European Journal of Mineralogy, 30 (2018), 859–868] in which the ideal chemical formula of the mineral is revised as (Ca,Na,☐)19Ti8Fe3+4Fe2+4(AsO3)28F, with no water molecules or hydroxyls, and with fluorine as an essential constituent. These data were examined carefully by the CNMNC officers and were considered reliable. Accordingly it was agreed to modify the formula of cafarsite in the official IMA List of Minerals.

Complimenti agli autori e scopritori delle 4 nuove specie italiane (ma ovviamente a anche a tutti gli altri che hanno lavorato per le specie estere...).

E che specie...! Congratulazioni a Gianluca che entra nel club, e una nota di rammarico per la gasparite-(La), minerale trovato per la prima volta a Molinello nei lontani anni '90 che per una serie di disgraziate circostanze non è entrato nei Nostri Minerali!

L'ekebergite, dedicata a Anders Gustav Ekeberg, potrebbe avere analogie con l'achalaite (supergruppo della columbite)?:

Achalaite Fe2+TiNb2O8 mon C2/c 9.422 11.427 5.120 90.00 90.12 90.00 4
Ekebergite Fe2+ThNb2O8 mon P2/c 9.815 5.629 5.224 90.00 93.520 90.00 4

La jeankempite, dedicata alla curatrice del A. E. Seaman Mineral Museum dal 1975 al 1986, Jean Petermann Kemp Zimmer (1917–2001), potrebbe definirsi il deidratato quasi-polimorfo della guérinite...
