Abstract
Sm/Nd isotopic age determination showed that Xiongshan dike swarm was at 585.7 Ma +/- 30 Ma. The trace element geochemistry and Sr/Nd/Pb iso tope geochemistry studies indicate that the dike swarm was products of back-are basin spreading ridge and the magma originated from the depl eted mantle region which was metasomatized by LILE-rich liquids/melts derived from subduction slab.
