SouthEast Timor Offshore

This schematic interpretation of a North-South cross-section, between the Northern Australian Shelf and the Banda Volcanic arc, explains the global tectonic context of the region, in which two convergent subduction zones seem more than likely, one explaining the Wetar volcanic arc and the other the plunging of the Australian lithospheric plate under the Wetar volcanic arc with formation of the Timor accretionary complex, as illustrated below.

This tentative geological interpretation of a seismic line of the SE Timor offshore does not refute the conjecture than the Australian lithospheric plate plunges under the Banda volcanic arc (Wetar volcanic arc) creating an important accretionary wedge with young forearc sedimentary basin, The Timor oceanic trough highlights the limit between descending ant the overriding plates.
