of the crust around the North Sumatra area. Proc. 25 th Ann. Conv. Indon. Petrol. Assoc., p. 81-91.
(Structural discontinuity around N Sumatra effect of split in descending oceanic plate along continuation of
Investigator Ridge Transform Fault. Discontinuity reflected by sharp change of Sumatra Fault, volcanic line
offset and major changes to strike of Batee fault and Batee trench. Area around discontinuity low gravity
anomaly with higher anomaly in center, indicating low density body of mantle material intruded by higher
density igneous material in center. Gravity model pattern reflects thinning of crust beneath N Sumatra due to
regional tensional stresses of mantle depth at ~20 km depth)

(Pasemeh Block is small intra-montane basin near Pageralam in Barisan Mts, behind Gumai Mts. Miocene
stratigraphy with Talang Akar quartz sandstones and baturaja Limestone suggests it was western extension of S
Sumatra basin. Surface oil and gas seeps and thermogenic hydrocarbons (incl. high-CO2 gas) in first
exploration well Ruas-1 suggest working petroleum system in Muara Dua area in SE of block. Quality of
seismic data poor, due to presence of young near-surface volcanics)

(Sumatra fore-arc basin subsiding trough between rising subduction complex and elevated continental core. Up
to 4 km of Miocene-Recent on E flank of basin over unconformity cut across Paleogene continental margin that
was uplifted and disrupted in Late Oligocene. Large step-like offsets of paleo-shelf edge attributed to rightlateral
strike-slip faults, splaying across fore-arc from Sumatra Fault Zone. Offsets up to 100 km+, producing
marginal re-entrants that became sites of turbidite-filled basins behind growing Neogene accretionary prism.
Larger re-entrants may be floored with oceanic crust. Seaward flank of fore-arc basin migrated W during
Neogene subduction. By late M Miocene, trench slope break was near sea level and formed shelf edge high.
Thrusting and folding related to subduction probably decreased gradually upslope until LatePliocene, when
large flexures and E-directed reverse faults developed)
