Native element minerals

Top

Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals and intermetallic elements, semi-metals and non-metals. This group also includes natural alloys, phosphides, silicides, nitrides and carbides.

There are 32 elements (18 metals, 5 nonmetals and gases) that can be found in nature in their elemental form. Metals give a metallic luster on their polished sides, some nonmetal and semimetal minerals too.

Nickel–Strunz Classification -01- Native elements

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses the Classification of Nickel–Strunz (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[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
