Abstract: Continental wrench shear basins and back-arc basins are developed on the present stable northern Sundaland. Different basin geometries and structural patterns among Cenozoic basins in northern Sundaland indicate different origins and/or timing of basin formation. Wrench faulting has played a significant role in the formation of these Cenozoic basins. The collision of the Indian Subplate with the Eurasian Plate during early Cenozoic has caused a redistribution of stress within this region. Zones of weakness have been reactivated or created by these stress field changes, thus initiating the subsidence of these basins. The episodic initiation of Cenozoic basins may have begun as early as Jurassic and continued in Eocene-early Oligocene and Late Miocene.
