J.V. Hepworth (ed.) Tungsten Geology symposium, Jiangxi, China, 1981, ESCAP/RMRDC, p. 217-231.
(In NE Bangka discontinuous serpentinites at Pemali Mine; viewed as trace of southern continuation of Triassic
Raub-Bentong suture of Malay Peninsula by Pulunggono & Cameron 1984)

Ann. Conv. Indon. Petrol. Assoc., IPA08-E-124, 18p.
(Reservoir model of 1972 NSO gas discovery, 100km off N Sumatra. Producing since 1999. 415' gas column in
E-M Miocene Malacca Lst reefal buildup. Area ~7 x 10km, OGIP 2.7 TCF gas. NSO gas ~32.5% CO2 and
1.5% H2S)
Suseno, P.H., Zakaria, N. Mujahidin & E.A. Subroto (1992)- Contribution of Lahat Formation as hydrocarbon
source rock in South Palembang Area, South Sumatera, Indonesia. Proc. 21st Ann. Conv. Indon. Petrol. Assoc.,
1, p. 325-337.
(Lahat or Lemat Fm mainly coarse volcanic rocks, but in some areas also claystone/ shale, like Benakat Shale.
Such sediments organic-rich and in oil window. Mixed Type II- III kerogens may yield oil and gas. Biomarkers
suggest Lahat and Talang Akar source rocks are identical)
Susianto, A., E.S. Utoro & S. Grahia (2006)- Oligocene- Early Miocene paleogeography models South Balam
Trough, Central Sumatra Basin. Proc. 35 th Ann. Conv. Indon. Assoc. Geol. (IAGI), Pekanbaru 2006,
PITIAGI2006-053, 16p.
(S Balam Trough one of most prolific petroleum systems in C Sumatra Basin. Paleogeographic maps made for
three chronostratigraphic intervals. In Oligocene syn-rift time half grabens created with lake deposits in center
(Pematang Brown Shale), bordered by fan deltas. Late Oligocene map of early post-rift phase illustrates
Pematang Upper Red Bed formation deposition. In late post-rift Early Miocene more shallow marine influence,
with fluvial and deltaic deposition (Menggala Fm))
Susilawati, R. & C.R. Ward (2006)- Metamorphism of mineral matter in coal from the Bukit Asam deposit,
South Sumatra, Indonesia. Int. J. Coal Geol. 68, p. 171-195.
(Miocene coal of Bukit Asam in S Sumatra mostly sub-bituminous, consistent with regional burial. Effects of
Plio-Pleistocene igneous intrusions produced coal with vitrinite reflectance up to 4.17% (anthracite).
Unmetamorphosed coals contain well-ordered kaolinite and quartz. Heat-affected coals, with Rv >1.0%,
dominated by interstratified illite/smectite, poorly crystallized kaolinite and paragonite)

Strait, Indonesia. Tectonophysics 467, p. 55-71.
(Sunda Strait opening initiated in early Late Miocene following M Miocene onset of Sumatra fault system.
Three major graben systems/ pull-apart basins: W and E Semangko and Krakatau. Prior to Late Miocene most
of Sunda Strait and surroundings probably developed in non-marine environment.)

Sunda forearc basins off southwest Sumatra and southwest Java. Marine Geol. 219, 2-3, p. 133-154.
(20 seismic lines in SW Sunda arc margin between Manna and W Java show fore-arc basin structures and
stratigraphy since Late Paleogene. Paleomorphology of Cretaceous continental margin persisted until
Oligocene and paleoshelf margin extended NW off Sumatra. Two structural events between Late Oligocene-
Pliocene. Back thrust-faulting along S border of fore-arc basin and initiation of Cimandiri FZ in Late
Oligocene; Sumatra and Mentawai FZ initiated in Pliocene. Four Neogene sedimentary cycles. Volcanic
activity abundant since late M Miocene. Turbidite deposition common along and seaward of basin slope during
sea level lows in late M Miocene and L Miocene)
