a, b Tectonic units of China (a) and the Qinling-Dabie orogen (b) showing the location of the Poshan Ag-Pb-Zn deposit (modified from Chai et al.25). c A photograph showing the occurrence of acanthite in the high-grade ores that contain abundant calcite and chlorite and variable proportions of acanthite and native silver. d Acanthite occurring both as anhedral crystals and tiny inclusions in calcite. e Native silver that replaced acanthite in calcite. Aca, acanthite; Ag, native silver; Cal, calcite; Chl, chlorite.
