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.

Three fossil teeth reported from the Upper Cretaceous of West Timor are the only known fossils of Mosasaurus-type marine reptiles in the eastern Tethys region. However, there is some uncertainty about the exact locality of origin of these fossils.

Plio-Pleistocene Seismic Stratigraphy of the Java Sea between Bawean Island and East Java Susilohadi Susilohadi; Tjoek Azis Soeprapto
Berita Sedimentologi Vol 32, No 1 (2015)
Publisher : Ikatan Ahli Geologi Indonesia

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: Tectono-stratigraphic Evolution of Western Gorontalo Bay, Indonesia Parinya Pholbud
Berita Sedimentologi Vol 22, No 1 (2011)
Publisher : Ikatan Ahli Geologi Indonesia

Gorontalo Bay exists as one of eastern Indonesia’s mystery basins in terms of its tectonic evolution and stratigraphy. Detailed interpretation of newly acquired regional 2D seismic data provides an understanding of the tectono-stratigraphic evolution of the western part of Gorontalo Bay.The formation of western Gorontalo Bay and adjacent areas is related to thermal subsidence initiated during the Early Miocene, associated with plate tectonic collision in Sulawesi (—23 Ma). This event initiated the development of the fore-arc basin along a NE-SW trending zone of weakness in Oligocene and older basement rocks. The NE-SW trending basin was filled by thick deep marine sediments. Subsidence was interrupted by a later uplifting event along the southeastern margin.Carbonates became dominant in this basin following the formation of a thick carbonate platform. The shallow marine carbonates were developed widely in the basin before rapid subsidence to the present-day deep water (2 km depth). This rapid subsidence is the result of the Celebes Sea subduction and trench rollback during the Pliocene (—5 Ma) to Recent.The results from this study imply that this basin potentially has a petroleum system for future hydrocarbon exploration according to the depositional environments. Hydrocarbon could be sourced from mature deep marine sediments in the basin centre. Mixed grain rocks, fractures and local unconformities within the sedimentary mega sequences potentially form economical stratigraphic plays. These should be the major targets for hydrocarbon exploration in this area.

A Photographic Journey through the Cretaceous-Tertiary Stratigraphy of the Meratus Mountains-Barito Basin Margin, SE Kalimantan J.T. (Han) van Gorsel
Berita Sedimentologi Vol 34, No 1 (2016)
Publisher : Ikatan Ahli Geologi Indonesia

The SE margin of the Barito Basin shows a relatively simple succession of WNW dipping beds, brought to the surface during Late Miocene or younger uplift of the Meratus Mountain Range. Outcrops of Cretaceous - Miocene rocks can be studied east of the Trans-Kalimantan Highway East and NE of Banjarmasin, between Martapura in the south and Rantau and Kandangan in the north.A vast body of literature exists on the geology of this region. For references see the 'Bibliography of the geology of Indonesia and surrounding areas' (online at www.vangorselslist.com)The photos shown here were taken by the author in 2010, during a fieldtrip reconnaissance along the uplifted eastern margin of the Barito Basin along the SW Meratus Range. I’d like to thank Afin Sjapawi and Ellen de Man (ExxonMobil) and Agus Pujubroto and Roy Widiarta (Sugico) and others for guidance and help with logistics.

The Effects of Eustatic Sea Level Change in the Development of Carbonate Reservoir: An Overview Herman Darman
Berita Sedimentologi Vol 10, No 1 (1998)
Publisher : Ikatan Ahli Geologi Indonesia

There are some major factors that control the variations in stratal patterns and lithofacies distributions within carbonate rocks. They include tectonic subsidence, eustatic change of sea-level, sediment volume, and climate. However, the major control over carbonate sedimentations is the eustatic change of sea-level.The cyclic changes in global sea level produce reciprocal sedimentations that alternately open and shut off transport of terrigenous clastics across the shelf into the basain. These clastics are highly involved in carbonate deposits development. During high stand of sea level, carbonates are the dominant lithologies that accumulates on the shelf, shelf margin, and in the basin. During succedingly lower stands of sea level, terrigenous clastics progrades across the shelf, and initial clastic sedimentation occures as they by-passes the slope and accumulates in the basin.Sea-level changes not only controls the carbonate sedimentation, but also controls the thickness and the internal structures of the carbonate rocks. Various depositional environments produce by the sea level changes cause the heterogeneity of carbonate reservoir. The sea level changes are highly related to the carbonate reservoir creation, therefore it is important to understand their relationship.

Interplay between Submarine Depositional Processes and Recent Tectonics in the Biak Basin, Western Papua, Eastern Indonesia Bertoni, Claudia; Álvarez, Juan
Berita Sedimentologi Vol 23, No 1 (2012)

The offshore Biak Basin between Biak and Yapen Islands is a transtensional pull-apart basin. Deposition along basin margins is strongly influenced by active faulting. The bathymetric map of the basin shows submarine depositional processes occurred during relatively recent tectonic activity.

Archaeology of disaster in Indonesia: where are we now? Truman Simanjuntak; Marlon Ririmasse
Berita Sedimentologi Vol 47, No 3 (2021)
Publisher : Ikatan Ahli Geologi Indonesia

Natural disasters are a phenomenon that shaped the Indonesian Archipelago. Earthquakes and volcanic activities have become periodic experiences in the lives of people in this region. The geographical characteristics of Indonesia which are located at the confluence of active plates and part of the global volcanic chain are natural factors that make these islands vulnerable to disasters. Cultural historical studies have recorded various phenomena of past natural disasters in the archipelago. Some have had minimal impact, but others have resulted in the loss of civilization. Although the issue has become the important part of the civilization and profile of Indonesia, the archaeological study of disasters has not well developed. The existing studies so far are still very partial with the fragmentary results. Characterized with this complex character, the study of archaeological disaster requires a multidisciplinary approach. This paper attempts to discuss the archaeology of disasters in Indonesia including the background, current conditions and the prospects of future development. Particularly in discussing the role of local wisdoms in dealing with disasters as part of the civilization of the archipelago.

Reservoir Potential of Neogene Rocks in the Biak Island and Its Surrounding Areas Alviyanda Alviyanda; G.M. Lucki Junursyah; Rahmat Saragih

Biak Basin is located offshore to the immediate west and southwest of Biak Island. The basin contains up to 7,000m thick of sediments, which may be thermally mature to generate hydrocarbon if source rocks are present. The stratigraphy of the Biak Basin is generally dominated by carbonate sequences of Early to Late Neogene. The basin was drowned during the Oligocene, which could have led to source rock accumulation during this period. Then, carbonate platform facies were deposited massively above and can be of potential reservoir. The Neogene carbonates consist of two depositional sequences, namely Early Neogene sequence that contains Wainukendi, Wafordori, and Napisendi Formations; and Late Neogene sequence that contains Korem and Wardo Formations. A Late Miocene unconformity separates the two carbonate sequences.Reservoir rock potential of the Neogene carbonates has been evaluated by using quantitative parameters. Based on the evaluation, grainstone interbedded crystal limestone from the Napisendi Fm members has porosity ranging from 8.84% – 29.5% which can be categorized as good to special. Porosity types of the rock vary from intercrystalline, intracrystalline, and fracturing to vuggy. Secondary porosity occurred due to diagenetic rocks processes such as compacting, cementing, dissolution and dolomitization.
