摘要：

<正>We report Pb isotopic compositions for feldspars separated from 57 orthogneisses and 2 paragneisses from three exhumed UHPM slices as North Dabie zone(NDZ), Central Dabie zone(CDZ) and South Dabie zone(SDZ) in Dabie orogen, central China. Precursors of the orthogneisses are products of bimodal magmatic events at Neoproterozoic, those in the NDZ emplaced into the lower crust and those in the CDZ and SDZ into middle or upper crust, respectively.
