A talc mine located 0.8 km (2,700 feet) NE of Talcville.
Note to mineral list:
Material labelled " tirodite" from the International Talc Company mine, Talcville, New York, USA, 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.
