The Phuket-Slate Belt terrane can be traced for 1700 km from Phuket to Mandalay. It is characterized by very thick Early Permian diamictite and was emplaced by dextral strike-slip faulting in the Late Cretaceous–Palaeogene. Southwards the bounding-fault system extends to Sumatra and aligns with the restored proto-Indian-Ocean India–Australia transform when Greater India was moving towards its collision with Eurasia. This coupling with the north-going India plate resulted in up to about 450 km of dextral shift on the terrane’s bounding fault system. Post-emplacement sinistral movement on the crosscutting Mae Ping and Three Pagodas Faults resulted in the terrane’s present outline.
