Ziel der Reise / Objectives of Cruise:

Cruise SO139 GINCO3 investigated the accretionary complex at the Sunda arc off southern Sumatra and western Java; geological, geochemical, geothermal, and biological methods were applied (3000 km profiling with swath mapping and sediment echosounding systems; 101 sampling and probing stations). From the thin sediment cover of the accretionary complex AC we sampled Pliocene/Pleistocene to recent muddy sediments with volcanic ash and turbiditic intercalations. At the northern graben shoulder we sampled rocks of continental provenance" (Miocene claystone, greenstone, diabas, andesite, Quarzite). From the same structure we recovered Vestimentifer sp., a tubeworm specialised to vent areas. A vent site exhibited the highest heat flow (153mW/m2) and it is the first one discovered in a forearc basin without known active volcanism.
