Ag may be replaced by minor Cu and Bi by minor Pb.
Colour:
Steel-gray to tin white
Crystal System:
Monoclinic
Name:
Named in 1953 by Edward Wilfrid Nuffield from the Latin pavo (= peacock) in honor of Martin Alfred Peacock [January 15, 1898 Edinburgh, Scotland - October 30, 1950 Toronto, Ontario, Canada], Canadian mineralogist and crystallographer, Professor of Mineralogy (1937-1950), University of Toronto, for his many contributions to the study of mineral sulfosalts, culminating in the posthumously published Atlas of X-Ray Data for the ore minerals. Peacock was an eminent morphological crystallographer and a pioneer in X-ray mineralogy in Canada.
