3.1 Revised formula for peprossiite-(Ce)

In the IMA List of Minerals the current formula of peprossiite-(Ce), (Ce,La)(Al₃O)${}_{\mathrm{2}/\mathrm{3}}$B₄O₁₀, is not charge-balanced. Following the approval of the new mineral peprossiite-(Y) (IMA 2024-046; this Newsletter) and the re-examination of the latest analytical data on holotype peprossiite-(Ce) (American Mineralogist, 85, 586–593, 2000), it was agreed to modify the formula to CeAl₂(B_3.67Si_0.33)O_10.67.

3.2 Revised mineral symbols

After the approval of the new mineral nioboixiolite-(Fe³⁺) (IMA 2024-057; this Newsletter), for which the symbol Nbix-Fe³⁺ is adopted, it was agreed that all minerals including an extended Levinson suffix in their name should contain the same suffix in the symbol. Accordingly, the symbol for three newly approved minerals is modified as follows:

• ixiolite-(Fe²⁺) – new symbol Ix-Fe²⁺ (old symbol Ix-Fe changed)

• ixiolite-(Mn²⁺) – new symbol Ix-Mn²⁺ (old symbol Ix-Mn changed)

• nioboixiolite-(Mn²⁺) – new symbol Nbix-Mn²⁺ (old symbol Nbix-Mn changed)

This is an executive decision taken by the CNMNC officers.
