Alfred W. Jolliffe
Formula:
NiAsSe
Colour:
White
Lustre:
Metallic
Hardness:
6 - 6½
Specific Gravity:
7.10 (Calculated)

Member of:
Cobaltite Group
Name:
Named by L.J. Cabri, J.H.G. Laflamme, A.C. Roberts, A.J. Criddle, and L.J. Hulbert in 1991 in honor of Alfred "Fred" Walton Jolliffe (8 May 1907, Winnipeg, Manitoba, Canada - 5 August 1988), geologist with the Geological Survey of Canada and professor at Queen's University. His early geological mapping of the Beaverlodge area in northern Saskatchewan for the G.S.C. encouraged commercial exploration in the area.
