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, naturally occurring alloys, semi-metals and non-metals. The Nickel–Strunz classification system also includes the naturally occurring phosphides, silicides, nitrides and carbides. The following elements occur as native element minerals or alloys: == 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 (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() 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 (ινος ''inos'' ), fibre) * * *Phyllo: sheet (from Greek φύλλον ''phyllon'', leaf) * * *Tecto: 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 * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Native element minerals」の詳細全文を読む スポンサード リンク
