ABSTRACT
Seismic multi-channel and magnetic data acquisition of Gorontalo deepsea basin with 457 kms length has been carried out by Marine Geological Institute, Research and Development Agency of Energy and Mineral Resources Department. Gorontalo basin is one of frontier and deepsea basins in eastern part of Indonesia. Its basin has 510 kms length, 120 kms width and 1000 – 4000 m water depth.
Based on seismic interpretation and then be integrated with magnetic data, this basin has been controlled by normal faults and half-graben indication. The central part was found basement high. This area also occured volcanic activity of Colo Montain in Una-una Island. based on seismo-stratratigrapy analysis, north-western part of this basin was characterized high energy complex sediment. Geological structure analysis indicate extension tectonic as early basin forming. In the eastern part of Togian island, the geological structure was dominantly influenced by obduction between Banggai-Sula micro-continent and ophiolite complex of eastern Sulawesi.
Modeling of chronostratigraphy that influenced by tectonic processes was created to give regional concept of basin forming. The tectonic processes of this basin give important implication to be probably found two types of hydrocarbon trap i.e. build-up reef and combination trap of structural/stratigraphy.
Key words: seismic stratigraphy, tectonic, Gorontalo basin, hydrocarbon trap
