Neoproterozoic plutonic rocks from the western Gyeonggi massif, South Korea: Implications for the amalgamation and break-up of the Rodinia supercontinent

► Early Neoproterozoic arc magmatism from the western South Korea related to the assembly of Rodinia. ► Middle Neoproterozoic anorogenic alkali plutons in the same area related to the disruption of Rodinia. ► These Neoproterozoic plutons provide important constraints on a regional tectonic link associated with evolution of Rodinia in East Asia.
