Sub-chapter V.1 contains 893 papers on the geology of the Sulawesi region.
Today Sulawesi is a triple junction of three major tectonic plates, Eurasia to the west, Pacific to the NE and Australia- New Guinea- Indian Ocean to the South and East. Its peculiar K-shape reflects a Cretaceous- Recent history with multiple episodes of subduction, collision and dismemberment of the active margin by hyperextension.
The ‘arms’ of Sulawesi represents three fundamentally different geologic provinces:
Intensely folded Late Cretaceous ‘flysch’ is overlain unconformably by less-deformed Eocene clastics with coals, which were surveyed in detail in the early 1900's, but were never deemed commercial. These are overlain by widespread Late Eocene Nummulites platform carbonates, and capped by thick Miocene and younger volcanics.
The tectonics of Sulawesi today is dominated by a few large sinistral strike-slip fault zones (Palu-Koro, Matano and Malili-Kendari). These faults accommodate the NW relative movements of parts of Sulawesi due to the continued convergence of Pacific, Australian and Eurasian Plates after the M Miocene collision of the Bangai-Sula microcontinent (Magetsari et al. 1987, etc.). As documented by paleomagnetic data, this convergence also caused the 60° counterclockwise rotation of the SW arm of Sulawesi (Panjaitan and Mubroto, 1994) and 90° clockwise rotation of the North arm.
This currently active NW-SE relative motion of the Sulawesi region also created young accretionary prisms/ fold-and-thrust belts at the N side of the North Arm (with subduction of Celebes Sea oceanic crust) and at the W side of West Sulawesi (with probable consumption of much of Makassar Straits basin floor below W Sulawesi in the last 10 My; e.g. Pubellier et al. 2005) .
East Sulawesi is characterized by one of the world's largest ophiolite complexes. Age of obduction is believed to be Late Eocene- Early Oligocene. .Below the relatively flat-lying ophiolite cover is a poorly known, but significant Late Triassic- Cretaceous marine sediment section. Milsom et al. (2000) suggested E Sulawesi, Buton, Buru and Seram were parts of a single microcontinent that separated from Australia in the Jurassic and collided with the Eurasian margin to form the Sulawesi orogen in the Oligocene.
