The second list of additions and corrections to the Glossary of Mineral Species (1995).

INTRODUCTION

As stated in the "Note added in proof" to The First List of Additions and Corrections to the Glossary of Mineral Species 7th Edition (1995), a major revision of the classification and nomenclature of the Amphibole Group has been published in several mineralogical journals. I have spent many hours with that report and this article is the result.

I have attempted to summarize the report by Leake et al. (1997), but I highly recommend that the original paper be consulted by readers interested in this complex group of minerals. So far, it has appeared in the Canadian Mineralogist 35, 219-246 (1997), Mineralogical Magazine 61, 295-321 (1997), the European Journal of Mineralogy 9, 623-651 (1997), and the American Mineralogist 82, 1019-1037 (1997).

An interesting aspect of the new classification is the probable absence of examples in Nature to fit some of the names and definitions given in the report. As I have said to several people, we now have a wonderfully constructed set of pigeonholes, but we are not sure that there are pigeons in each of these. Quite possibly, there are data in the voluminous literature dealing with amphiboles which represent some of these defined names and I would like to encourage anybody who might recognize any of these to contact me. I then will attempt to get the authors who published the data to: (1) characterize the minerals and submit proposals for their approval to the Commission on New Minerals and Mineral Names of the International Mineralogical Association or (2) provide material to a group here in Toronto which will carry out the necessary work.

I am pleased to acknowledge the assistance of the following people. Prof. Bernard E. Leake, University of Glasgow, gave freely of his time to answer my questions about the new classification of which he is the senior author. Dr. Joel E. Grice, Canadian Museum of Nature, pointed out that two of the names listed in the report require the prefix "potassic". Mr. Malcolm E. Back, Royal Ontario Museum, offered several suggestions which greatly improved an earlier draft of this article. Dr. John C. Schumacher, Albert-Ludwigs Universitat, Freiburg, Germany, kindly provided his expertise regarding the calculation of formulae for the sadanagaite-magnesiosadanagaite series. Dr. Wendell E. Wilson, Mineralogical Record, was very encouraging and supportive of this project. Lastly, we all owe a debt of gratitude to the members of the Amphibole Subcommittee of the Commission on New Minerals and Mineral Names, I.M.A. who spent many hours working on the classification; unfortunately, they are too numerous to list here.

AMPHIBOLE GROUP

The classification of the Amphibole Group has been revised by a subcommittee of the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA). The report on the new classification by Leake et al. (1997) has been published (or is in press) in many mineralogical journals, including those mentioned above in the introduction. Readers interested in this group of minerals should consult that report.

Seventy-five species names are listed in the report with their end member formulae and, according to Prof. Leake (personal communication, 21 May 1997), there are analyses of all of these species which fall into the compositional fields which define them. In other words, all of them are considered to exist in Nature. However, many of the species in the list have not been characterized formally, nor have they been submitted for approval to the CNMMN.

In terms of anions, almost all of the amphibole species are defined with twenty-two oxygen ions and two hydroxyl (OH) groups. Exceptions are kaersutite and ferrokaersutite with twenty-three oxygens and one hydroxyl and ungarettiite with twenty-four oxygens. However, some of the species have fluorine-dominant analogues and the names of such species should have the prefix "fluoro"; for example, richterite and its fluorine-dominant analogue, fluororichterite, are known. On the other hand, although fluorocannilloite exists the hydroxyl-dominant analogue is not yet known; if it is found and approved by the CNMMN, it would receive the name cannilloite. A similar case involves ferroleakeite (hydroxyl-dominant), which has not been found although fluoro-ferroleakeite is known and has been approved by the CNMMN; in contrast, leakeite (hydroxyl-dominant) has been approved by the CNMMN but a fluorine-dominant analogue has not been found. It is interesting to note that analytical data exist in the literature for at least two amphiboles which fall into the hastingsite field and which are chlorine-dominant; one of these is almost completely characterized but the data for the other consists only of chemical analytical data. Once they are characterized and subsequently approved by the CNMMN, their names would be prefixed by "chloro".

Some of the species found in Nature might require the addition of other prefixes such as "potassic"; an example is potassic-fluororichterite. Leake et al. (1997) list and define the following prefixes: alumino, chloro, chromio, ferri, fluoro, mangano, permangano, mangani, potassic, sodic, titano, and zinco. Where assigned, they are an integral part of the species name.

In an attempt to differentiate between the names of possible amphibole species and those known to exist in Nature, two modified lists are presented here. The lists contain all of the names recognized by Leake et al. (1997) and, in addition, prefixed names of species known to occur in Nature which have been properly characterized have been added. The species whose names are given in bold type are the equivalents of species that are known to have been formally approved or "grandfathered" by the CNMMN. Most of these were recognized in the Glossary of Mineral Species 1995. New species approved since its publication, are also given in bold type. Where necessary, the names required by the new classification scheme have been applied. Some species may have been overlooked, but without a thorough examination of all the amphibole analytical data in the literature, this is difficult to overcome. It must be stressed that even if a set of analytical data for an amphibole indicates that a name from the classification scheme applies to that mineral, a formal proposal must be made to the CNMMN for approval of the species.

Some of the names require special discussion: actinolite, fluorocannilloite, fluoro-ferroleakeite, fluororichterite, potassic-fluororichterite, manganocummingtonite, manganogrunerite, sadanagaite, magnesiosadanagaite, and ungarettiite.

Actinolite has been retained by the subcommittee for members of the tremolite-ferro-actinolite series, where the ratio Mg/(Mg+[Fe.sup.2+]) is greater than 0.5 and less than 0.9.

The species fluorocannilloite, fluoro-ferroleakeite, and ungarettiite are listed in The First List of Additions and Corrections to the Glossary of Mineral Species 7th Edition (1995), but the spelling of the first two names has been changed by the report.

Fluororichterite and potassic-fluororichterite appeared in the Glossary of Mineral Species 1995, with slightly different spellings.

The names manganocummingtonite and manganogrunerite replace the names "tirodite" and "dannemorite", respectively.

The minerals sadanagaite and magnesiosadanagaite present some problems. The formulae given in the new classification for these two minerals are, respectively, [Mathematical Expression Omitted] and Na[Ca.sub.2][[Mg.sub.3][([Fe.sup.3+],Al).sub.2]][Si.sub.5][Al.sub .3][O.sub.22][(OH).sub.2]. In both formulae, [Fe.sup.3+] [greater than] Al, but calculation of the empirical formulae from the original chemical analytical data for the type specimens of these two species shows that Al [greater than] [Fe.sup.3+]. The formulae listed for these species in this paper have been written with Al [greater than] [Fe.sup.3+]. There appear to be problems with the original chemical data for magnesiosadanagaite and the calculation of its formula is not completely satisfactory. However, other analyses in the literature confirm the existence of magnesiosadanagaite. In addition, the type materials named sadanagaite and magnesiosadanagaite are, strictly speaking, potassicsadanagaite and potassic-magnesiosadanagaite, respectively. The prefix "potassic" is required because K [greater than] 0.50 in both formulae.

The first list contains all of the amphibole species names arranged alphabetically. The second list gives the amphibole species arranged by subgroup.

The standard amphibole formula is [Mathematical Expression Omitted]. The components A, B, C, T, and X of the formula correspond to the following crystallographic sites:

A one site per formula unit;

B two M4 sites per formula unit;

C a composite of five octahedral sites made up of 2 M1, 2 M2, and 1 M3 sites per formula unit;

T eight tetrahedral sites in two sets of four per formula unit;

X two sites per formula unit.

The ions considered normally to occupy these sites are:

[ ] (empty site) and K (at A only), Na (at A or B), a (at B only), L-type ions: Mg, [Fe.sup.2+], [Mn.sup.2+], Li, and rarer ions of similar size such as Zn, Ni, Co (at C or B), M-type ions: Al (at C or T), [Fe.sup.3+], and, more rarely, [Mn.sup.3+], [Cr.sup.3+] (at C only), High-valency ions: [Ti.sup.4+] (at C or T), [Zr.sup.4+] (at C only), Si (at T only), Anions: OH, F, Cl, O (at X).
