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 Canadaâs 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)).
