and thickness of sediments entering trench, mainly from Bengal Fan. Sumatran Fault System apparently
connected to spreading centers in Andaman Sea. Part of Sumatra SW of Sumatra Fault zone moves NW with

zone tectonics. Amer. J. Sci. 280, p. 193-223.

heavy mineral distribution in Miocene sandstones of the North Sumatra Basin. J. Southeast Asian Earth Sci. 10,
3-4, p. 177-190.
(Heavy minerals record changes in provenance in N Sumatra Basin. E Miocene Belumai Mb (Peutu Fm)
sandstones derived from granitic terrain in E or SE. Uplift of Barisan Mts in early M Miocene led to
introduction of sand from W or SW (Keutapang Fm), from metamorphosed pelitic rocks intruded by granites.
Contemporaneous intermediate- acidic volcanic rocks also involved. Chrome spinel abundant in Lower
Keutapang but rare in Upper Keutapang Mb, indicating ultramafic rocks important component of Barisan
Mountain source in M Miocene, but insignificant by Late Miocene)

but series of small faults across broad frontal accretionary wedge)

J. Southeast Asian Earth Sci. 14, 5, p. 351-371.
(AFT and OM data suggest Tertiary sediments exposed in Ombilin Basin have low-medium thermal maturities
(Ro-average 0.39–0.50%). This suggests outcrops studied were not part of main Paleogene-Neogene graben
system that was subsequently inverted, but likely represent marginal, rift shoulder sedimentation)

(Bengkalis Depression N-S Paleogene graben complex: chain of interconnected lozenge-shaped depressions
with several side grabens. It formed by extension, with complexities related to basement inhomogeneities.
Neogene-Recent compression caused uplift, erosion and destruction of graben and its fill, progressively from S.
Compression and tectonic overprinting of earlier extension produced major basement block uplift, normal fault
