WITHDRAWAL OF AN APPROVED MINERAL
Proposal 2005-012 was approved (mineral and name) in June 2005. The authors have recently submitted additional data on this phase which show that it is merely a monoclinic polytype of mackelveyite-(Y), namely mackelveyite-(Y)-2M. The approval for this proposal is thus
withdrawn.

IMA 2006-051 has not yet been approved, the handling of this proposal has been suspended until its relation with another mineral is resolved.
I sincerely apologise for this unfortumate error, also towards the authors of the proposal!

Yes Alfredo, 2005-012a: withdrawn. In mindat it can be exist as polytype-2M of mckelveyite.
IMA 2006-055 is the Fe3+ analogue of clinozoisite-(Sr) (ex "niigataite").
Ciao.

"IMA 2006-055 is the Fe3+ analogue of clinozoisite-(Sr) (ex "niigataite")."
Thanks, Marco. Of course, you're right.
This means it must get a new root name?

Dear Ernst,
thank you for the quickly explanation.
And about IMA 2006-052 that is the Fe3+-analogue of IMA 2006-051?
Is the 2006-052 an approved mineral?
Many thansk.
Best regards.

Yes of course; I have disclosed the second possibility. Thank you very much.
