Name:
Named after the (then) type locality of Tirodi, India.
Discontinued (1997) amphibole name. The "type" material from the Tirodi Mine (1938) is an alkali- and Mn-rich amphibole later called parvowinchite, and finally ghoseite. Since then the name tirodite was predominantly used to describe Mn-rich amphiboles within the Mn-rich cummingtonite/manganocummingtonite range. Mostly this is now classified as clino-suenoite.
Note: Material described as "tirodite" from the International Talc Company mine, Talcville, New York, USA (Segeler, 1961), has been shown to be manganocummingtonite by electron microprobe analyses (by Mike Hawkins, curator at the NY State Museum mineral collection). See further discussions in http://www.mindat.org/mesg-7-206424.html and Ghose & Yang (1989).
