“…Dufrénoy (1856) stated that the "variété manganésifère" from Piemonte is named "piemonite". Hey (1955) Burns & Strens (1967). Nonetheless, there seems to be a general problem Table 1.…”

“…This timing gives epidote precedence. Pistacite is not listed among accepted mineral names (in spite of its frequent use) by Hey (1955) but referenced as synonym of epidote. Other obsolete names (Dana, 1896) are oisanite, puschkinite (six other spellings have also been used, e.g., pushklinite in Dufrénoy, 1856), achmatite, beustite and escherite.…”

“…However, X-ray diffraction data are mandatory to confirm this relationship. Hey (1955) referenced also treanorite as synonym for "allanite" and additionally the following "allanite" varieties: Cerepidote, cerorthite, yttrio-orthite, magnesium-orthite, and mangan-orthite. The "orthite" vs. "allanite" controversy was resolved in 1986 by the Commission on New Minerals and Mineral Names, IMA, in favor of "allanite".…”

The key cation-sites M3 and A1 (and, in principle, M2) determine the root name. In both clinozoisite and allanite subgroups no prefix is added to the root name if M1 = Al. The prefixes ferri, mangani, chromo, and vanado indicate dominant Fe 3+ , Mn 3+ , Cr 3+ , and V 3+ on M1, respectively. In the dollaseite subgroup no prefix is added to the root name if M1 = Mg. Otherwise a proper prefix must be attached; the prefixes ferro and mangano indicate dominant Fe 2+ and Mn 2+ at M1, respectively. The dominant cation on A2 (other than Ca) is treated according to the Extended Levinson suffix designation. This simple nomenclature requires renaming of the following approved species: Niigataite (old) = clinozoisite-(Sr) (new), hancockite (old) = epidote-(Pb) (new), tweddillite (old) = manganipiemontite-(Sr) (new). Minor modifications are necessary for the following species: Strontiopiemontite (old) = piemontite-(Sr) (new), androsite-(La) (old) = manganiandrosite-(La) (new). Before a mineral name can be assigned, the proper subgroup has to be determined. The determination of a proper subgroup is made by the dominating valence at M3, M1, and A2 expressed as M 2+ and or M 3+ , not by a single, dominant ion (i.e., Fe 2+ , or Mg, or Al). In addition, the dominant valence on O4: X -or X 2-must be ascertained. The dominant trivalent cation on M3 determines the name, whereas the A2 cation appearing in the suffix has to be selected from among the divalent cations. (2) Allanite and dollaseite subgroups: For the sites involved in the charge compensation of a heterovalent substitution in A2 and O4 (i.e. M3 in the allanite subgroup; M3 and M1 in the dollaseite subgroup), identification of the relevant end-member formula must take into account the dominant divalent charge-compensating octahedral cation (M 2+ ) and not the dominant cation in these sites.Formal guidelines and examples are provided in order to determine a mineral "working name" from electron-microprobe analytical data.

“…STANDARD texts (Ross and Hendricks, 1945;Hey, 1955;Strunz, 1966;Nemecz, 1981) all attribute the first description of the mineral volkonskoite to K/immerer (1831). However, in his account (taken from the letter, dated 10 April 1831, he sent from 'Petersburg' to von Leonhard) K/immerer merely states:…”

All three polymorphs exhibit a single broad asymmetric band at 140 cm-1 (not shown), the assignment of which is not known.Conclusions. The variation in spectra described here for the three polymorphs differs from that described previously for various specimens of leadhillite (sensu strictu) by Russell et al. (1983) who showed that the relative intensity of OH, CO3, and SOn absorption bands varied, and proposed that mutual substitution of these ions occurs within the leadhillite structure.The X-ray powder pattern of macphersonite is distinctly different from those of susannite and leadhillite (Livingstone and Sarp, 1984), which themselves, as reported by Mrose and Christian (1969), are virtually indistinguishable. It is shown here, however, that all three polymorphs are readily distinguished by their IR spectra. Moreover, the appearance in a high resolution IR spectrum of the closely spaced 691, 687 cm-~ doublet may be diagnostic for macphersonite.

“…Kirwanite is described (Thomson, 1836) as opaque, dark olive green in colour, with fibrous texture, the fibres divergent, forming brushes and filling cavities 'in a kind of basaltic rock'; hardness 2, S.G. 2.941, analysis SiO 2 40.50, AI20 311.41, FeO 23.91, CaO 19.78, H20 4.35, total 99.95%. Lacroix (1885) re-examined kirwanite optically and suggested that it was an altered amphibole mixed with epidote and quartz and his conclusion has been generally accepted (Hey, 1962;Leake, 1978).…”

X-ray powder, optical, infrared, and chemical data suggest that kirwanite is an amphibole of composition (Na, K)o.loCa1.8o(Fe2+,Mn)3.1oMgo.79Fe3~4Alo.78Si7AsO22(OH)2 and thus corresponds to ferriferro-hornblende (Leake, 1978). The type locality, originally given as the NE coast of Ireland, is most likely Dunmore Head, Co. Down. Kirwanite occurs in the groundmass and the vesicles of variolitic andesite dykes of the Mourne dyke swarm. Thomson's original analysis of kirwanite was probably made on a mixture and the name should not be used for an amphibole species.
