Sl. Ren et al., GEOCHRONOLOGY, GEOCHEMISTRY AND TECTONIC IMPLICATIONS OF XIONGSHAN DIABASIC DIKE SWARM, NORTHERN FUJIAN, SCIENCE IN CHINA SERIES D-EARTH SCIENCES, 40(4), 1997, pp. 411-417
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.
