IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses the classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).

• Abbreviations:
  • "*" – discredited (IMA/CNMNC status).
  • "?" – questionable/doubtful (IMA/CNMNC status).
  • "REE" – Rare-earth element (Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu)

  • 03.C Aluminofluorides, 06 Borates, 08 Vanadates (04.H V^[5,6] Vanadates), 09 Silicates:
    • Neso: insular (from Greek νησος nēsos, island)
    • Soro: grouping (from Greek σωροῦ sōros, heap, mound (especially of corn))
    • Cyclo: ring
    • Ino: chain (from Greek ις [genitive: ινος inos], fibre)
    • Phyllo: sheet (from Greek φύλλον phyllon, leaf)
