Petrogenesis and metallogenic implications of Late Cretaceous I- and S-type granites in Dachang–Kunlunguan ore belt, southwestern South China Block

The southwestern part of the South China Block is one of the major Sn, W and Cu metallogenic provinces related to Mesozoic granitoid suites. However, the genetic relationship between the magmatic petrogenesis and metallogeny is not well-constrained. Here we evaluate the petrogenesis of Late Cretaceous granites and their link to regional metallogeny from the Dachang–Kunlunguan ore belt in the eastern part of the province. This belt includes...
