About WyllieiteHide

Peter J. Wyllie
deep bluish-green to deep oily-green, gray-green, to greenish-black
Vitreous, Sub-Metallic
4 - 4½
Crystal System:
Named by Paul B. Moore and Jun Ito in 1973 in honor of Peter John Wyllie (8 February 1930, London, England - ), Professor of Geology, University of Chicago (1965-1983) and the California Institute of Technology (1984-1999), for his work on granite melts in dry and aqueous conditions. He received the Roebling Medal in 2001.

The original wyllieite from the Victory Pegmatite, Custer, South Dakota, USA (Moore and Ito, 1973) was redefined by Moore and Ito (1979) as ferrowyllieite-MnNaNa, but their new wyllieite, designated by them as wyllieite-□NaCa, was not formally described except for a published chemical analysis and the implicit assertion that their material otherwise conformed to the wyllieite group (Min Mag 43:227, 1979).

The mineral rosemaryite is named for his wife.
