About Donnayite-(Y)Hide

00394270015411581631120.jpg
Joseph D. H. and Gabrielle Donnay
Formula:
NaCaSr3Y(CO3)6 · 3H2O
Colour:
pale yellow to yellow, colorless, white, grey, brown to reddish brown
Lustre:
Vitreous
Hardness:
3
Specific Gravity:
3.30
Crystal System:
Triclinic
Name:
Named donnayite in 1978 by Chao et al. in honor of Joseph Désiré Hubert Donnay (6 June 1902, Oreye, LiÚge province, Belgium - 8 August 1994, Mont Saint Hilaire, Quebec, Canada), Professor of Mineralogy and Crystallography, Johns Hopkins University, Baltimore, U.S.A. and his wife Gabrielle (Gai) Donnay-Hamburger (1920, Landeshut, Silesi, Germany (now Poland) - 4 April 1987, Mont St. Hilaire, Quebec, Canada), Professor of Crystallography, McGill University, Montréal, Canada, for their significant contributions to crystallography. He was awarded the 1971 Roebling medal. She is known for solving the complex structure of tourmaline, and later solved numerous other structures. The suffix/modifier was added by the IMA in 1987 to conform to the Levinson rule for species with essential REE, indicating, in this case, predominant yttrium.
Two polytypes are known, donnayite-(Y)-1A and donnayite-(Y)-3R.

The UM1992-05-CO:CaCeLaNaSr phase, although suggested to be polymorphous with donnayite-(Y), slightly differs in terms of chemistry.

Re-examination of donnayite-(Y) type specimens showed that the original description contains data collected on two different phases with simplified formulae NaCaSr3Y(CO3)6.3H2O and Na2Sr3)6.3H2O. The latter corresponds to alicewilsonite-(YCe)(IMA 2020-055). A another specimen with donnayite-(Y), with the ideal formula NaCaSr3Y(CO3)6.3H2O was redefined by IMA as the holotype of donnayite-(Y) (IMA 2022, Proposal 22-F)
