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).〔 〕 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.〔 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)). James A. Ferraiolo was responsible for it at Mindat.org.〔(Strunz Classification )〕 The IMA/CNMNC supports the Nickel–Strunz database. == 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 , 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 * * * * Subclass: phylloborates * * * * Subclass: tectoborates * * Nickel-Strunz class 07: Sulfates, Selenates, Tellurates * * * Class: sulfates, selenates, tellurates * * * Class: chromates * * * Class: molybdates * * * Class: tungstates * * Nickel-Strunz class 08: Phosphates, Arsenates, Vanadates * * * Class: phosphates * * * Class: arsenates * * * Class: vanadates * * Nickel-Strunz class 10: Organic Compounds * * * Class: organic compounds * Classification of minerals (silicates) * * Nickel-Strunz class 09: Silicates and Germanates * * * Class: silicates * * * * Subclass 09.A: nesosilicates * * * * Subclass 09.B: sorosilicates * * * * Subclass 09.C: cyclosilicates * * * * Subclass 09.D: inosilicates * * * * Subclass 09.E: phyllosilicates * * * * Subclass: tectosilicates * * * * * 09.F: without zeolitic H2O * * * * * 09.G: with zeolitic H2O; zeolite family * * * * Subclass 09.J: germanates 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「Nickel–Strunz classification」の詳細全文を読む スポンサード リンク
