摘要：
A detailed study of isotope and trace element on the volcanic-intrusive complex in Yanbei, Jiangxi Province is reported. All rocks of the complex have similar crystallization age, relatively high (Sr-87/Sr-86)(i) and delta(18)O, high Pb-207/Pb-204, lower epsilon(Nd) and old Nd model age. They also possess high Rb/Sr and F/Cl, weak Ce and intense Eu negative anomalies. These characteristics clearly demonstrate that the volcanic-intrusive complex is the product of the evolution of cognate magma, end the initial magma was formed by the partial melting of Early-Middle Proterozoic metasedimentary rocks.
