The available petrochemical data indicate that volcanic rocks in the Sanshui basin of Guangdong Province are characteristic of the island-arc tholeiite-calc-alkaline series.Their K-Ar ages range from 43 to 64 Ma, corresponding to Early Tertiary. The Nd-Sr-Pb isotopic correlations give two binary mixing trends, indicating a mixed source of Leiqiong depleted mantle, seawater and altered sediments pertaining to subduction.Our studies have confirmed the existence of an ancient subduction zone beneath the South China continent, which is considered to have resulted from the suturing of various terrains in southern China.
