Why is IMA2011-083 a new mineral
Alexander Hölzel

29th Jan 2012 13:49 UTCAnatoly Kasatkin
Chinner and Dixon described in the 1973 paper you are referring to "osumilite-(K,Mg)" from Ireland. They did not get it formally
approved by IMA (Mindat assigns IMA 1975-002 number to keyite).
In 1980 IMA rejected the name "osumilite-(K,Mg)":
http://rruff.info/rruff_1.0/uploads/MM43_1053.pdf
Thus, current IMA list of minerals mentions "osumulite-(K,Mg)" as being discredited and "osumilite-(Mg)" described in 2008 by Seryotkin et al. (EJM 20, 191-198) as published without approval by CNMNC:
http://pubsites.uws.edu.au/ima-cnmnc/IMA2009-01%20UPDATE%20160309.pdf
So Mg-dominant analogue of osumilite, being described repeatedly in past, was never formally approved by IMA.

""Dear Marco,
I would like to elucidate the situation in reference to the comment of Etienne Medard on your site: "What surprises me about Osumilite-Mg is that Miyashiro's type material for Osumilite (American Mineralogist 41: 104-116, 1956) was the Mg-dominant end-member. How come the Fe-dominant end-member is now osumilite, and there is a need for describing a new Mg end-member ?"
Really, it is not an end-member, but an intermediate member of the series osumilite – osumilite-(Mg). Fe-dominant osumilite from Sakkabira, Japan, has Fe2+:Mg=1.33:0.65. Our data (supplementary) confirm that the mineral from Sakkabira is Fe-dominant and its approximate formula is (K0.7Na0.3)(Fe1.1Mg0.8Mn0.1)(Al2.5Fe0.5)(Al1.7Si10.3)O30.
There was a need to describe osumilite-(Mg) because there was no complete descriptions of this mineral on the same type material.
Mg-dominant (at the octahedral site) analogues of osumilite have been described repeatedly (Armbruster and Oberhänsli, 1988; Balassone et al., 2008; Seryotkin et al., 2008). However this mineral has the status N (“published without approval by the CNMNC”). In the IMA list of minerals, for osumilite-(Mg) the reference Seryotkin et al. (2008) for the description of a technogenetic sample is given. Moreover, the formula of osumilite-(Mg) in the IMA list of minerals, KMg2O30,does not correspond to the formula KC0.83NaB’0.10(Mg1.78Fe0.16Mn0.03Ti0.03)A(Al2.88Fe0.12)T2(Al1.91Si10.09)T1O30 presented in the cited paper. “Osumilite-(K,Mg)” has been discredited by the IMA CNMNC. Our work was aimed at a complete investigation of a type specimen to be approved by the IMA CNMNC as a valid species, with a definite name.
You can place this my comment on your site, if you want.
Best wishes
Nikita Chukanov.""
