Mineralogy, fluid inclusions and S-Pb-H-O isotopes of the Erdaokan Ag-Pb-Zn deposit, Duobaoshan metallogenic belt, NE China: Implications for ore genesis

The recently discovered Erdaokan Ag-Pb-Zn deposit is located in the Duobaoshan gold-copper metallogenic belt in the eastern part of the Central Asian Orogenic Belt. The ore-bodies occur mainly as veins hosted in the breccia. Three stages of mineralization, including early magnetite-quartz-pyrite, middle silver-sulfide-bitumen-quartz and late carbonate stages, were recognized. Here we report results from electron microprobe analysis (EPMA),...
