“…In the Java Sea there is a broadly horizontal regional unconformity at the base of a Cenozoic section, and beneath it are synforms containing 5-10 km of section interpreted as Precambrian to Permian-Triassic (Granath et al 2011). Below the Cenozoic section south of Java is a broadly flat-lying sequence several kilometers thick, which Deighton et al (2011) and Nugraha & Hall (2012) suggest is Mesozoic or older. The lack of significant deformation of the Cenozoic section, and the thick pre-Cenozoic section, suggests that this sequence is a fragment of strong Australian lithosphere now incorporated within a weaker Sundaland.…”

Southeast (SE) Asia is surrounded by subduction zones causing intense seismicity and volcanic activity. Subduction has been the principal tectonic driver of collisions that caused the growth of continental SE Asia, and most recently the collision of Australia with SE Asia. The western part of SE Asia, Sundaland, is a heterogeneous and weak region, reflecting processes that can be observed today in the east, where there are subduction zones in different stages of development. A close relationship between subduction rollback and extension has caused dramatic elevation of land, exhumation of deep crust, and spectacular subsidence of basins, observable with remotely acquired images and seismic and multibeam data obtained from oil exploration. New dating indicates that subsidence and uplift occurred at high rates during short time intervals. Laboratory studies, modeling, and reconstructions provide valuable insights, but field-based studies continue to present surprises and new discoveries essential for interpretations of the geological history of the region.

“…The biostratigraphic top information (Shell interpretations) from these wells are the main reference for our mid and late Tertiary age-controlled stratigraphic interpretation ( Figure 5). The Cilacap-1 well was drilled by Union Texas but appears to have been terminated before returning cuttings (Deighton et al, 2011).…”

“…An alternative is that Unit F is older than Middle Eocene. Deighton et al (2011) suggested this unit to be Mesozoic based on its position and seismic character similarities with Mesozoic and/or Palaeozoic sections from the Australian NW Shelf. If the rifting that affects Unit E is Middle Eocene then Unit F is older.…”

“…These seismic lines south of Java have imaged a deep stratified sequence ( Figure 3 and Figure 4) which is restricted to East Java and is absent beneath the West Java forearc. The age of the lower section is still uncertain but Deighton et al (2011) suggested it may be Mesozoic. This paper uses the new seismic data to assess the age of the lower section and acquire a better understanding of the tectono-stratigraphic evolution of the East Java forearc.…”

Cenozoic subduction of the Indo-Australian plate beneath Java began in the Middle Eocene. The East Java forearc preserves a record of Cenozoic sedimentation and tectonic history, and information about the character of the deeper crust. Based on new seismic data, morphology analysis, and correlation with offshore wells and geology on land, the East Java forearc stratigraphy can be divided into six tectono-stratigraphic units with three major unconformities.
