Abstract:The Yangtze Craton hosts significant Zn-Pb deposits in Neoproterozoic to Carboniferous carbonates (> 60 Mt Pb + Zn metals), accounting for 30% of China's Zn-Pb resources. However, determining the timing of zinc and lead mineralization in these reservoirs is challenging. This study employs LA-ICP-MS U-Pb geochronology on calcites to date Zn-Pb deposits hosted in Lower Cambrian limestone in the Huayuan orefield. Three generations of calcite formation were dated: the first recorded the pre-ore deposition of Lo… Show more
