(Three main unconformity bounded units in Late Eocene- Pliocene of C Sumatra: (1) Kelesa Synthem: Late
Eocene-Oligocene synrift sequence, equivalent to Lower Red Beds, Brown Shale, Upper Red Beds; (2) Sihapas
Synthem: Late Oligocene- M Miocene post-rift, equivalent with Lakat, Tualang and Telisa Fms. Terminated by
structural inversion of Binio Event in M Miocene and Barisan Mts uplift at 13 Ma; (3) Petani Synthem: M
Miocene- Recent inverted basin sequence, equivalent to Binio and Korinci Fms. Binio Event local
unconformity. Minas Event is youngest deformation in Plio-Pleistocene (~5 Ma))

(New seismic in Sumatra margin fore-arc. Area of oblique subduction with two large strike-slip faults parallel
to subduction trench, Sumatra fault on Sumatra and Mentawai fault offshore, separating accretionary prism
from fore-arc basin. Widespread Paleogene uplift and erosion followed by Miocene subsidence, evidenced by
two transgressive-regressive shelf sequences. In Pliocene-Quaternary fore-arc basin segmented into several
sub-basins (Aceh, Simeulue and Nias basins) by compressional zones or strike-slip faults. Subsidence rate
increased, producing sequence 3 for Pliocene, and 4 for Quaternary. Local variations in sediment thickness
indicate tectonics prevail over eustacy)
