Tongling region in the Lower Yangtze River belt (LYRB) is one of the most important Cu-polymetal producers in China (Fig. 1). Metal deposits are closely associated with and genetically related to the dioritic rocks in the region (e.g., Chang et al., 1991; Mao et al., 2011). The petrogenesis of Early Cretaceous dioritic intrusions and their genetic relation with Cu-Au deposits have been debated in the past decade (Xie et al., 2012 and references therein). This contribution aims to provide firmer constraints on the petrogenesis of the dioritic rocks and Cu-Au mineralization, based on in-situ geochemistry of zircon from ore-forming dioritic intrusions in the Tongling region.
