Nickel–Strunz classification
Nickel–Strunz classification is a scheme for categorizing minerals based upon their chemical composition, introduced by German mineralogist Karl Hugo Strunz (24 February 1910 – 19 April 2006) in his Mineralogische Tabellen (1941).[1] The 4th and the 5th edition was also edited by Christel Tennyson (1966). It was followed by A.S. Povarennykh with a modified classification (1966 in Russian, 1972 in English).
As curator of the Mineralogical Museum of Friedrich-Wilhelms-Universität (now known as the Humboldt University of Berlin), Strunz had been tasked with sorting the museum's geological collection according to crystal-chemical properties.[1] His book Mineralogical Tables, has been through a number of modifications; the most recent edition, published in 2001, is the ninth (Mineralogical Tables by Hugo Strunz and Ernest H. Nickel (31 August 1925 – 18 July 2009)).[2][3] James A. Ferraiolo was responsible for it at Mindat.org.[4] The IMA/CNMNC supports the Nickel–Strunz database.[5]
Nickel–Strunz code scheme
The Nickel–Strunz code scheme is NN.XY.##x, where:
- 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 an add-on letter
Nickel–Strunz mineral classes
The current scheme divides minerals into ten classes, which are further divided into divisions, families and groups according to chemical composition and crystal structure.[4]
- elements
- sulfides and sulfosalts
- halides
- oxides, hydroxides and arsenites
- carbonates and nitrates
- borates
- sulfates, chromates, molybdates and tungstates
- phosphates, arsenates and vanadates
- silicates
- organic compounds
IMA/CNMNC mineral classes
IMA/CNMNC proposes a new hierarchical scheme (Mills Hatert), using the Nickel–Strunz classes (10 ed) this gives:
- Classification of minerals (non silicates)
- Nickel–Strunz class 01: Native Elements
- Class: native elements
- Nickel–Strunz class 02: Sulfides and Sulfosalts
- Class 02.A – 02.G: sulfides, selenides, tellurides (including arsenides, antimonides, bismuthinides)
- Class 02.H – 02.M: sulfosalts (including sulfarsenites, sulfantimonites, sulfobismuthites, etc.)
- Nickel–Strunz class 03: Halogenides
- Class: halides
- Nickel–Strunz class 04: Oxides
- Class: oxides
- Class: hydroxides
- Class: arsenites (including antimonites, bismuthites, sulfites, selenites and tellurites)
- Nickel–Strunz class 05: Carbonates and Nitrates
- Class: carbonates
- Class: nitrates
- Nickel–Strunz class 06: Borates
- Class: borates
- Subclass: nesoborates
- Subclass: soroborates
- Subclass: cycloborates
