REVISED CHEMICAL FORMULAE

A paper on the mineral satimolite has been recently published [Mineralogical Magazine, 82 (2018), 1033-1047] in which the ideal chemical formula of the mineral is given as KNa2(Al5Mg2)[B12O18(OH)12](OH)6Cl4·4H2O, with magnesium 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 satimolite in the official IMA List of Minerals.

Re: New minerals approved by IMA CNMNC in December 2018 and January 2019

Come anticipato in altro messaggio l'ultima parte di minerali approvati a fronte di proposal datati 2018, sarà approvata entro il 28 febbraio 2019.
Globalmente il totale ammonta a più di 165.
Con questa tranche di approvazioni le valide specie minerali ammontano a 5468.

Come si piò vedere nessuna specie nuova con località-tipo italiana, ma gli autori italiani non mancano!
Alcune specie sono veramente "esotiche"!!!

Nel PDF del giornale sussiste un errore come citare la nickeltyrrellite è infatti errato: qui è stato debitamente corretto in: How to cite: Förster, H.-J., Ma, C., Grundmann, G., Bindi, L., and Stanley, C.J. (2019) Nickeltyrrellite, IMA 2018-110. CNMNC Newsletter No. 47, February 2019, page 200; European Journal of Mineralogy, 31, 199–204.
