Alice E. Wilson
Formula:
Na2Sr2YCe(CO3)6 · 3H2O
Colour:
pale yellow to yellow, lemon yellow, green yellow, orange-yellow, pale green to green, pale grey to grey, green grey, beige, and colourless
Lustre:
Vitreous
Hardness:
3
Specific Gravity:
3.37 (Calculated)
Crystal System:
Triclinic
Name:
Named in honor of Alice Evelyn Wilson (26 August 1881, Cobourg, Ontario, Canada - 15 April 1964, Ottawa, Ontario, Canada), geologist and paleontologist with the Geological Survey of Canada. She was Canada’s first female geologist and the recognized authority on the fossils and rock of the Ottawa-St. Lawrence Valley. She became the first female Fellow of the Royal Society of Canada in 1938. The suffix indicates the dominant essential rare-earth elements, according to IMA nomenclature.
The Ce analogue of alicewilsonite-(YLa). Unique combination of elements (at the upload time). A rare example of separation of REEs (rare earth elements) into separate structural positions (compare the chemically similar bainbridgeite-(YCe); and bainbridgeite-(NdCe)).

Epitaxial Relationships of Alicewilsonite-(YCe)Hide

Epitaxial Minerals:
WeloganiteNa2Sr3Zr(CO3)6 · 3H2O
Donnayite-(Y)NaCaSr3Y(CO3)6 · 3H2O
Bainbridgeite-(YCe)Na2Ba2YCe(CO3)6 · 3H2O
Epitaxy Comments:
alicewilsonite-(YCe) on donnayite-(Y) and vice versa. Similar relationships were observed between alicewilsonite-(YCe) and the recently approved new species bainbridgeite-(YCe), Na2Ba2YCe(CO3)6 ⋅ 3H2O. On one specimen, alicewilsonite-(YCe) was found forming an epitactic overgrowth on weloganite, Na2Sr3Zr(CO3)6 ⋅ 3H2O. Homoepitactic growth is also common.
