Re: Lumping and splitting: Toward a classification of mineral natural kinds

Nel testo alcuni errori...
E.g. leggasi aluminoedtollite and edtollite al posto di "aluminoedtoilite and edtoilite" e francoisite-(Ce), francoisite-(Nd) al posto di "francoisite-Ce, francoisite-Nd" e ancora phosphuranylite in luogo di "phosphuranaylite".

Re: On the paragenetic modes of minerals: A mineral evolution perspective

Interessante!

Da notare che gli autori giudicano antropogenici una vasta serie di composti minerali: "anthropogenic minerals, for example as byproducts of mining (603 minerals)". Con lo stesso tipo di approccio io ne individuo un po' meno di 1000 (organici e prodotti di combustioni inclusi).

Re: The where of mineral names: Zimbabweite, St. Anne’s Mine, Mwami, Zimbabwe

La formula corretta è la seguente: Na(PbNa0.5K0.5)(Ta3Nb0.5Ti0.5)As3+4O18.

Re: IMA 2019-105 = niasite; IMA 2019-122 = johanngeorgenstadtite

Quasi sicuramente la formazione di queste due specie è dovuta al fuoco, così come la formazione in campioni della stessa località-tipo di aerugite, bunsenite, paganoite, petewilliamsite e xanthiosite.
