摘要
In this paper, the authors report new elemental and Sr-Nd-Pb isotopic data in Tongling region. The distinctly geochemistry characteristics indicate the adakitic rocks and the large-scale Cu-Au mineralization of Tongling and the Lower Yangtze River belt result from partial melting of the subducting oceanic crust.
