Abstract

Willyamite is recorded from this Pb-Zn-Ag-Sb deposit in Sardinia. EPMA results give the formula (Co (sub 0.71) Ni (sub 0.30) )SbS for the cobalt-richest willyamite. Coexisting ullmannite has only 0.2% Co, with Ni 28.4%. The willyamite shows a slightly yellower hue, similar reflectivity and very slightly higher polishing hardness than the ullmannite.
