Pyrosmalite-(Fe)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Fe2+8Si6O15(OH,Cl)10
Hardness:
Crystal System:
Trigonal
Name:
Named in 1808 by Johann Friedrich Ludwig Hausmann from the Greek πυρ = fire and οσμη = smell, because of the strong odor the mineral gives off when strongly heated. Renamed by IMA with a suffix -Fe, indicating its relationship to pyrosmalite-(Mn).
Pyrosmalite-(Fe)-Pyrosmalite-(Mn) Series.

"The mineral was originally named pyrodmalith (Hausmann 1808), then shortly after changed to pyrosmalite by Karsten (1808). History, crystallography and chemistry was discussed by Zambonini (1901, Zeitschrift für Krystallographie vol. 34, p.554-561), who remarked that all historical investigations was performed on material from Bjelke mine up until when material from Dannemora, Sweden was described by Lindström 1888. Essentially all investigations up until Zambonini displayed slight to moderate Fe > Mn, Zambonini’s own investigation on material from Nordmark confirmed this.
In the description of the new mineral manganpyrosmalite (Frondel & Bauer, 1953), it was acknowleged that six old (Fe-dominant) analyses together with the new (Mn-dominant) indicated a continuous solid solution series with Fe/(Fe+Mn) ratio from about 0.60-0.25. The old name pyrosmalite was retained for members with Fe>Mn and manganpyrosmalite was applied to members of the series with Mn>Fe.
In The iron end-member of the pyrosmalite series,from Pegmont lead-zinc deposit, Queensland, Vaughan (1986, Min. Mag. vol.50:527-531) reported an extremely iron-rich member of the series that had Fe/(Fe+Mn) ratio 0.92. Vaughan explained the nomenclature used by Frondel & Baur, and noted that the Pegmont material fell within the pyrosmalite field sensu stricto. However, Vaughan self in the article used “pyrosmalite” to designate the series and expressed an opinion that the nomenclature was unresolved. In a later short communication, Vaughan (1987, Min. Mag. vol.51:174) could report that the IMA Commission had resolved the nomenclature issue “and the Fe-rich species described in Vaughan (1986) is designated ferropyrosmalite”. This may briefly sound as Vaughan discovered a new species, when in fact he was decribing the most Fe-rich of the (Fe-rich) pyrosmalites. Thus, Vaughan was “only” enforcing a nomenclature revision, so that pyrosmalite came to designate the Fe-Mn solid solution series and the Fe vs Mn fields, came to bear names, ferropyrosmalite and manganpyrosmalite, that directly indicated the composition.
I think this is a good example of how name revisions get confounded with “new” discoveries and mineralogical history unfortunately gets erased.
"
(Johan Kjellman posting on Mindat forum)

"A slightly later paper by Stillwell and McAndrew (1957, Min. Mag., p. 371) also mentions Frondel and Bauer and states:
"In doing so (i.e. proposing the name manganpyrosmalite) they relegate the name pyrosmalite from that for a species as found with approximately equal amounts of Fe and Mn to that of a variety with Fe>Mn; this departure from the earlier usage is undesirable. The name pyrosmalite is here retained for all members of the isomorphous series."
(Jeffrey Vaughan, pers. comm. to Uwe Kolitsch)

The work of Yang et al. (2012) suggests the presence of disordered structural water in pyrosmalite-(Fe), consistent with infrared spectroscopic data measured from the same sample.
