...V.V. Sharygin Abstract Three minerals of the mayenite supergroup have been found in fluorellestadite-bearing metacarbonate rock (former fragment of petrified wood of ankeritic composition) from the dump at the Baturinskaya-Vostochnaya-1-2 mine. These are eltyubyuite Ca 12 Fe 10 3+ Si 4 O 32 Cl 6...

...Evgeny V. Galuskin; Frank Gfeller; Irina O. Galuskina; Thomas Armbruster; Radu Bailau; Viktor V. Sharygin Abstract The mayenite supergroup, accepted by the IMA-CNMNC (proposal 13-C), is a new mineral supergroup comprising two groups of minerals isostructural with mayenite (space group No. 220, I 4...

... from the mineral structure at about 550°C. Chlorkyuygenite crystallized initially as chlormayenite, which later was altered under influence of volcanic gases containing water vapour. In the first paper of this series we present a recommended nomenclature for the mayenite supergroup, and also redefine...

... structure characteristic of the mayenite supergroup. In fluormayenite 1/3 of the structural cages are occupied by fluorine. In fluorkyuygenite, in addition to fluorine and negligible amounts of OH, H 2 O molecules occupy about 2/3 of the cages. The holotype fluormayenite from Jabel Harmun has the crystal...

..., srebrodolskite–brownmillerite and mayenite-supergroup minerals are the main minerals commonly associated with gazeevite. Gazeevite is isostructural with zadovite and aradite; the 1:1 type AB 6 ( T O 4 ) 2 ( T O 4 ) 2 W , occurs together with the structurally related minerals of the nabimusaite series, 3:1 type...
