The geology of the Banggai-Sula microcontinent, eastern Indonesia

Australian crust in Indonesia

“…This suggests that there is another Permian-Triassic source. Acid magmatism of PermianTriassic age is known from the Bird's Head (Pieters et al 1983), and the Banggai-Sula Islands (Pigram et al 1985;Garrard et al 1988). Transport of Permian-Triassic zircons from the Tin Belt to SE Borneo is unlikely (Witts et al 2011) but their presence can be explained if they were eroded from the SW Borneo block itself.…”

Evolution of the boundary between the Philippine Sea Plate and Australia: palaeomagnetic evidence from eastern Indonesia

“…However, recent evidence indicates that this suggestion is incorrect; the ophiolite was obducted westward onto west Sulawesi at the end of the Oligocene (Parkinson, 1991), whereas thrusting of the ophiolite onto the western edge of the Sula Platform occurred in the latest Miocene (Garrard et al, 1988;Davies, 1990). There is no record of Late Oligocene-Early Miocene deformation at the western edge of the Sula Platform (Davies, 1990) and furthermore, the Sula Platform could not have moved along the Sorong Fault since the fault did not form until ~ 25 Ma.…”

The Caribbean: an oroclinal basin?

“…Hypocentre locations from supporting material to Engdahl et al (1998). (Garrard et al 1988) that moved west (Fig. 3) and collided with the East Arm of Sulawesi in the Late Miocene (Davies 1990).…”
