Formula:
(Na,Sr,K,REE)(Ca,Zr,Mn)(Ti,Fe)18Fe2O38
Member of:
Co-described with other unnamed group members: UM2006-05-O:CaFeKMnNaREESrTiZr, UM2006-06-O:CaFeKMnNaREESrTiZr, UM2006-08-O:CaFeKMnNaREESrTiZr, and UM2006-09-O:CaFeMnREESrTiZr.
CaFe-analogue of landauite. ~Zr analogue of UM2006-08-O:CaFeKMnNaREESrTiZr (not considering the Fe valency).
Note on the locality: "fenitized megaxenolith" within the Khibiny pluton; although the precise localization is not reported, it is almost undoubtedly the Kaskasnyunchorr site based on the listed, very characteristic, associates.
