Nickel–Strunz classification -05- carbonates

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)
**"PGE" – Platinum-group element (Ru, Rh, Pd, Os, Ir, Pt)
**03.C Aluminofluorides, 06 Borates, 08 Vanadates (04.H V ^{,6/sup> 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 enitive: 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
