Commentaar:


Material labelled " tirodite" from the International Talc Company mine, Talcville, New York, USA (Segeler, 1961), has been shown to be manganocummingtonite 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 the International Talc Company mine, Talcville, New York, USA, was confirmed to be anthophyllite by XRD performed by John Attard on a sample submitted by John Duck in April, 2012.

Accordingly, without confirmation, the identity of similar material may be either manganocummingtonite or anthophyllite. Visual identification or identification by fluorescent response is not possible.

Commentaar over activators en spectra:


The photoluminescence spectra, optical excitation spectra and PL decay curves of anthophyllite from Canada were obtained at 300 and 10 K by Aierken Sidike and Al.. The MnO content in the sample, determined using an electron probe microanalyzer, was high at 5.77 wt%. In the photoluminescence spectra obtained under 410nm excitation, bright red bands with peaks at 651 and 659nm were observed at 300 and 10 K, respectively. The origin of the red luminescence was ascribed to Mn2+ in anthophyllite from the analysis of the excitation spectra and photoluminescence decay times of 6,1–6,6 ms. In the PL spectra obtained under 240nm excitation at 300 K, a small violet band with a peak at 398 nm was observed. On the violet band at 10 K, a vibronic structure was observed. The origin of the violet luminescence was attributed to a minor impurity in anthophyllite.
