Recommended nomenclature for zeolite minerals: Report of the Subcommittee on Zeolites of the International Mineralogical Association, Commission on New Minerals and Mineral Names 论文

摘要

This report emboclies recommendations 011 zeolite nomenclature approved by the International Mineralogical Association,\nCommission on New Minerals and Mineral Names, In a working definition of a zeolite minerai used for this review, structures\ncontaining an interrupted framework of tetrahedra are accepted where other zeolitic properties prevail, and complete substitution\nby elements other than Si and Al is allowed. Separatespecies are recognized in topologically distincti ve compositional series\nin which different extra-framework cations are the most abundant in atornic proportions. To narne these, the appropriate\nchemical syrnbol is attached by a hyphen to the series name as a suffix, except for the names harmotome, pollucite and wairakite\nin the phillipsite and analcime series, Differences in space-group symmetry and in order-disorder relationships in zeolites\nhaving the same topologically distinctiveframework.do not in general provide adequate grounds for recognition of separate\nspecies. Zeolite species are not to be distinguìshed solely 011 the ratio Sì : Al except far heulandite (Si: Al < 4.0) and\nclinoptilolite (Si :AI.~ 4.0). Dehydration, parti al hydration, and overhydration are not sufficient grounds far the recognition\nof separate species of zeolites. Use of the term "ideal formula" should be avoided in referring to a simplified or averaged\nformula of a zeolite. Newly recognized species in compositional series are as follows: brewsterite-Sr, -Ba, chabazite-Ca,\n-Na, -K, clinoptilolite-K, -Na, -Ca, dachiardite-Ca, -Na, erionite-Na, -K, -Ca, faujasite-Na, -Ca, -Mg, ferrierite-Mg, -K, -Na,\ngmelinite-Na, -Ca,-K, heulandite-Ca, -Na, -K, -Sr, levyne-Ca, -Na, paulingite-K, -Ca, phillipsite-Na, -Ca, -K, and stilbite-Ca,\n-Na. Key references, type locality, origin ofname, chemical data, IZA structure-type syrnbols, space-group symmetry, unit-cell\nclirnensions, and comments Oll structure are listed far 13 compositional series, 82 accepted zeolite minerai species, and three\nof doubtful status. Herschelite.Jeonhardite, svetlozarite, and wellsite are discredited as minerai specìes names. Obsolete and\ndiscredited narnes are listed.
