(Sumatran fault in N Sumatra (1°S- 3°N) GPS-derived slip rates increase slightly N-ward from 23 mm/yr at
0.8°S to 26 mm/yr at 2.7°N. Banda Aceh embayment is extruded to NW at 5 mm/yr. N part of back arc basin is
part of rigid Sunda Shelf, while N forearc is subjected to extension nearly parallel to arc

margin identifies a new continental fragment that accreted to Sumatra during the Early Eocene. American

(Reconstruction of abyssal plains along W Australian margin reveals that, apart from Greater India and
Argoland, a third continental block (Gascoyneland) must also have rifted from Australia since Jurassic. From
132 Ma it formed the stretched continental crust of Exmouth Plateau and then oceanic crust of Gascoyne and
Cuvier abyssal plains. At 115 Ma Gascoyneland began moving N while Greater India continued W.
Gascoyneland would have reached W Sumatra at ~60 Ma. Woyla Group, consisting of the Sikuleh, Natal and
Bengkulu terranes, alongW coast of Sumatra, identified as oceanic arc, which accreted in Jurassic-Early
Cretaceous after formation of short-lived, narrow marginal seaand may overlie continental crust due to the
presence of the Sikuleh granitoid batholith. We propose Gascoyneland now buried beneath Woyla Terrane)
