Argentite (Ag2S> may replace sphalerite (ZnS) in which case migration and
substitution of the metallic element Zn by Ag is possible. Another possibility is the
dissolution of sphalerite and precipitation of the silver mineral (Fig. 157).

Geochemistry of Strata Bound Deposits in China
Nevertheless, the major industrial minerals are native silver and, most commonly
seen , argentite. Because of this, our emphasis is placed on the estimation of
solubilities of argentite so as to discuss, thereby, the conditions of formation of ...
