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 edited by Christel Tennyson too (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 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]
Classifications
- 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.
- 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 et al. 2009), 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; arsenides, antimonides, bismuthides
- Class 02.H – 02.M: sulfosalts; sulfarsenites, sulfantimonites, sulfbismuthites, 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
- Subclass: inoborates
