Re: New minerals (nomenclature/classification) approved by IMA CNMNC in October and November 2022
Ikorskyite, KMn3+(Si4O10)·3H2O, è un nuovo fillosilicato, membro della sotto-classe sepiolite-palygorskite (palysepiole, end–member (n = 1) of the palygorskite-sepiolite polysomatic series).
La struttura della fase è correlata a quella della silinaite, NaLi(Si2O5)·2H2O.
