The carbonate class in both the Dana and the Strunz classification systems include the nitrates.[1][2]

Nickel–Strunz classification -05- carbonates

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009).[3] This list uses the classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).[2]

  • 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)
    • "PGE" – Platinum-group element (Ru, Rh, Pd, Os, Ir, Pt)
    • 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)
      • Tekto: three-dimensional framework
  • Nickel–Strunz code scheme: NN.XY.##x
    • NN: Nickel–Strunz mineral class number
    • X: Nickel–Strunz mineral division letter
    • Y: Nickel–Strunz mineral family letter
    • ##x: Nickel–Strunz mineral/group number, x add-on letter

Class: carbonates
