BERITA SEDIMENTOLOGI aims to disseminate knowledge on the field of sedimentary geology to its readers. The journal welcomes contributions in the form of original research articles, review articles, short communications and discussions and replies. Occasionally, Berita Sedimentologi also includes field trip reports and book reviews, which are published only after going through peer-review processes. The main geographical areas of interest are Indonesia and SE Asia, however contribution from the rest of the world is also welcome. Berita Sedimentologi covers broad topics within sedimentary geology, particularly on depositional processes and their records in the rocks, petrology, sedimentology and stratigraphy of both siliciclastic and carbonate rocks; sequence stratigraphy, paleontology, biostratigraphy and sedimentary geochemistry. The journal also accepts articles on interdisciplinary research in sedimentary basin analysis, including large-scale basin geodynamics processes, mechanism of sedimentary basin formation, earth surface processes, sediment routing systems, petroleum geoscience and applied sedimentary geology analysis for mining and engineering geology.

Abstract

The southeast Java Sea forms a submerged part of the Sunda Shelf and lies on a relatively stable continental shelf, which reached its final form during the Quaternary. Marine geological investigations in this area have mostly been carried out as part of regional studies on the Sunda Shelf. Detailed studies, particularly for younger sequences, are lacking and, as a result, the neo-tectonics and response of the shelf area to extreme sea level fluctuations during Plio-Quaternary times are poorly known.A set of high resolution reflection seismic profiles totalling some 3750 line km has been studied. All data were acquired by the Marine Geological Institute of Indonesia, which ran the survey in the southeast Java Sea in 1989-1990. The data show that the Late Tertiary sedimentation in the study area partly occurred in half graben basins, mostly bounded by northeastward trending faults which may be related to the regional suture belts running from central Java to south Kalimantan. Towards Pliocene time, the sedimentation occurred in east-trending synclinal basins, which indicate the dominance of a northward tectonic compressional stress. This continued until the Early Pleistocene, as indicated by some local thickening of the Early Pleistocene deposits. Since then, further basin development appears to have ceased, and a tectonically stable condition may have been reached. Quaternary sedimentation gradually changed the basin morphology into a relatively flat plain characterised by multiple erosional features resulting from extreme sea level fluctuations.

Abstract

The presence of gas hydrates in deep marine sediments and their Bottom Simulating Reflectors (BSRs) on seismic lines can be used to estimate present-day surface heat flow. Despite its limited accuracy, the estimated heat flow is still useful as an input in thermal maturity modeling of a frontier basin.BSRs commonly occur at several hundred meters below the seafloor, in low latitudes generally in areas with water depth greater than about 700-1000m. They run parallel to the sea floor and may cross-cut lithological boundaries. They represent a phase boundary between a gas-hydrates-stable zone and underlying free gas- and water-saturated sediments. Since the depth of the hydrate- free gas phase change is a function of temperature, depth (pressure) and gas composition for a given gas composition (assuming hydrostatic pressure and mainly methane gas), the temperature gradient between seafloor and the BSR can be calculated from its depth. The temperature gradient can then be converted into heat flow, provided that thermal conductivity of the sediment is known.

Abstract

Exploration in frontier areas is always challenging and has resulted in the development of various new technologies including georeferenced, high resolution seafloor multibeam bathymetry and backscatter. The multibeam bathymetry data provides sea floor depth information, while the backscatter data records the amount of acoustic energy received by the sonar after interactions with the sea floor and are used to infer seabed features and materials. Interpretation of these new dataset combined with piston cores and seismic data have been conducted in the offshore of North Banggai Sula. This integrated approach has been termed as SeaSeepTM technology.

Abstract

During the colonial years there was little support from the Netherlands government for non-applied scientific work. The colonies had to pay for themselves and had to be profitable for the Netherlands; science was not considered to be a good investment. Nevertheless, a number of important oceanographic expeditions took place, for example, the Siboga and Snellius expeditions. Both were named after the ships that carried the scientists and both were paid for by the Netherlands government. The objective was to prove that the Dutch Indies were not only the best governed, but also the scientifically most developed tropical colony. Moreover there were the Dutch who needed to consolidate colonial rule by showing the flag over the whole archipelago. Germans, British, Americans and Japanese were encroaching on the Far East (New Guinea, Philippines, Malaysia and Taiwan) and in some ways the expedition can be considered as ‘gunboat science’. Even so, vast amount of prime oceanographical, hydrographical, biological and geological data were collected with state-of-the-art equipment.
