Notes on the mineral list:
— Material labelled "manganocummingtonite" or "tirodite" (both names discredited) from this locality has been shown to be clino-suenoite by electron microprobe (by Mike Hawkins, curator at the NY State Museum mineral collection). See further discussions at: http://www.mindat.org/mesg-7-206424.html
— Additional material labeled "tirodite" from this locality was confirmed to be anthophyllite by XRD performed by John Attard on a sample submitted by John Duck in April 2012.
— Visual identification, under daylight, of either mineral or from similar-looking tremolite, commonly together in samples, is not possible. However, under UV light the tremolite fluoresces yellow-orange and the clino-suenoite/anthophyllite fluoresces pink/reddish. Detailed analyses are still needed to separate the latter two minerals.

| ⓘ Anthophyllite Formula: ◻{Mg2}{Mg5}(Si8O22)(OH)2 |
| ⓘ Clino-suenoite Formula: ◻{Mn2+2}{Mg5}(Si8O22)(OH)2 Description: Analysed by Hawkins at the NY State Museum. |
| ⓘ Formula: ◻[Mn2+Na][Mg4Fe3+]Si8O22(OH)2 Description: "Segeler (1961) mistakenly referred to the manganoan cummingtonites from Talcville, New York as "tirodite," because the yellow amphibole from Tirodi contains substantial amounts of Mn and Mg. Unfortunately, Segeler's misidentification of manganoan cummingtonite as tirodite received the blessings of the IMA Commission on New Mineral Names". (Ghose & Hexiong 1989).
Tirodite was discredited in the 1997 paper on amphibole nomenclature as a synonym of Parvowinchite. Thus specimens of manganocummingtonite labelled as tirodite was erronously relabelled as "parvowinchite".
There are no evidence of significant Na content in these amphibioles. |
