6. Conclusions
- The U–Pb dating of the Zengudi and Tuobake granite porphyries from the Sanjiang area reveal that these granites were emplaced between 254 and 246 Ma, indicating that their emplacement occurred at the closure of the Paleo-Tethys Ocean during Late Permian to Early Triassic.
- Whole-rock geochemistry and zircon Hf isotopic compositions suggest that the granite porphyries are typical volcanic arc rocks formed in the continental arc setting after the subduction of oceanic crust. These rocks were originated from plagioclase-rich and clay-poor clastic source magmas which have likely undergone intensive fractional crystallization.
- The crust of the Jiangda-Weixi volcanic arc belt was thickened by eastward subduction of the Baoshan block during the closure of the Paleo-Tethys, which resulted in partial melting of the thickened crust.
