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.

Fossil-bearing Citalang Formation, Sumedang-Majalengka, West Java Rizal, Yan
Berita Sedimentologi Vol 47, No 3 (2021)
Publisher : Ikatan Ahli Geologi Indonesia

The Citalang Formation in Sumedang-Majalengka area comprises of various lithological units, including coarse-grained sandstones to conglomerates, greenish grey to dark grey claystone with sandstone and tuff interbeds, and pumice-bearing tuffaceous sandstones and tuff. All these units occur in the lower part of the formation and the contacts with older, underlying rock units are unconformable in several places.Vertebrate fossil fragments are frequently found in the lowermost part of the formation, especially within the coarse-grained sandstones to conglomerates unit. This unit also holds stone tools artefacts, which were made from different kind of stones and show quite simple or primitive shape. The age of Citalang Formation is not yet resolved and still needs to be researched. Some published literatures suggest Pleistocene while there are others that suggest Pliocene.

Host Rock Packaging in the Big Gossan - Kucing Liar Cu-Au Mineralization Type in the Grasberg-Ertsberg District, Papua Herman Setyadi; Wahyu Sunyoto
Berita Sedimentologi Vol 14, No 1 (2000)
Publisher : Ikatan Ahli Geologi Indonesia

The Grasberg-Ertsberg Mining District is located in the highlands of the central range Jayawijaya Mountains of Papua (Irian Jaya) province, Indonesia. The Grasberg-Ertsberg District is one of the richest mining districts in the world. The district contains six known skarn and porphyry copper deposits with mineable reserves. Total 1999 proven and probable reserves in the district are 2.5 billion tonnes at 1.13% Cu and 1.05 g/t Au, dominated by the Grasberg super-giant porphyry copper-gold deposit (1.9 bt @ 1.04% u, 1.04 g/t Au).Kucing Liar and Big Gossan deposits occur in the stratigraphy contact of New Guinea Group and Kembelangan Group. The other skarn system occurs associated with the contact of New Guinea group and Ertsberg Diorite. This paper presents a review of the copper-gold mineralization appears in the sedimentary units and/or stratigraphic controls and its potential around the Grasberg-Ertsberg district related to this mineralization type.

Short Communication: No Jurassic Sediments on Sumba Island? van Gorsel, J.T. (Han)
Berita Sedimentologi Vol 25, No 1 (2012)
Publisher : Ikatan Ahli Geologi Indonesia

Roggeveen (1929) described a small ammonite fragment from SW Sumba Island, provisionally identified as a Middle Jurassic species. It is associated with Inoceramus-type bivalves. The presence of Jurassic age sediments within the intensely deformed Mesozoic section of Sumba was accepted by some authors and this presence of Jurassic ammonites and bivalves was used to support the presence of Australian continental basement crust on Sumba and South Sulawesi.However, subsequent workers on the geology of Sumba have been unable to find additional fossil evidence for the presence of Jurassic sediments on Sumba; the oldest rocks that could be reliably dated are of Late Cretaceous age.Three ammonite specialists were consulted to check the identification of the ammonite illustrated from Sumba by Roggeveen (1929). They concluded that the fragment could not be reliably identified and could well be a Cretaceous species, and also suggested that the associated Inoceramus looked like Cretaceous species. There is therefore no reliable evidence for the presence of any rocks older than Late Cretaceous on Sumba, and it remains to be demonstrated whether basement of Sumba contains any Australia-derived continental material.

The Use of Trace Fossils in Delineating and Interpreting Stratigraphic Discontinuities S. George Pemberton; James A. MacEachern; Murray K. Gingras
Berita Sedimentologi Vol 19, No 1 (2004)
Publisher : Ikatan Ahli Geologi Indonesia

Trace fossils represent both sedimentological and palaeontological entities and as such, represent a unique blending of potential environmental indicators in the rock record. Trace fossils and trace fossil suites can be employed effectively to aid in the recognition of various discontinuity types and to assist in their genetic interpretations. Ichnology may be employed to resolve surfaces of stratigraphic significance in two main ways: 1) through the identification of discontinuities using substrate-controlled ichnofacies (i.e., the firmground Glossifungites ichnofacies, the hardground Trypanites ichnofacies, and the woodground Teredolites ichnofacies), and 2) through careful analysis of vertical softground (penecontemporaneous) ichnologic successions (analogous to facies successions). Integrating the data derived from substrate-controlled ichnofacies (so-called omission suites) with palaeoecological data from vertically and laterally juxtaposed softground ichnological successions greatly enhances the recognition and interpretation of a wide variety of potentially significant stratigraphic surfaces.

A Review of the Foraminiferal Biostratigraphy of the Melinau Limestone, Sarawak Peter Lunt
Berita Sedimentologi Vol 29, No 1 (2014)
Publisher : Ikatan Ahli Geologi Indonesia

A study of the Melinau limestone, especially in the continuous Melinau Gorge section, reviews taxonomic concepts of Adams (1965) in the Heterostegina- Tansinhokella- Spiroclypeus lineage, proves the presence of Middle Eocene 'Letter Stage' Ta, at the base of the Melinau Limestone, examines the nature of the Eocene- Oligocene boundary and the absence of Wilfordia sarawakensis Adams from other Tb Eocene limestones in the region. Strontium dating and biostratigraphy calibrated to GTS04 shows there to be a significant change in sedimentary rates or preserved thickness during mid-Oligocene (latest Tc or intra-Td times), but the disconformity noted by Adams (1970) was not found, probably due to poor exposure. Observations on the termination of the Melinau limestone agree with those of Adams (1965, 1970) and Wannier (2009), with an initial event near the Oligo-Miocene boundary (Te4 to Te5 boundary) and the youngest limestones dated as Te5, about 20.3 Ma.

On the 91/17 pattern in the brackish ichnofabric Arifullah, Ery
Berita Sedimentologi Vol 47, No 3 (2021)
Publisher : Ikatan Ahli Geologi Indonesia

From previous research, I have identified what ichnotaxa dominate each ichnofabric unit and how many ichnotaxa are taking up a share of the total observed ichnofabric units. The contribution of this paper is the 91/17 pattern. The point of this pattern is that only 17% ichnotaxa (6 of 34 ichnotaxa) had 91% of the total ichnofabric units that were observed. In addition, the six ichnotaxa tend to be more monospecific. These are the most effective strategies for the animal to survive by constructing the most essential structures. These strategies are common in brackish paleoecology in the fluvial-marine transition zone.

Sandstone Diagenesis: Establishing Threshold Temperature and Depth of Porosity Deterioration, Penyu Basin and Tenggol Arch, Offshore Peninsular Malaysia Franz L. Kessler; John Jong
Berita Sedimentologi Vol 41, No 1 (2018)
Publisher : Ikatan Ahli Geologi Indonesia

A review of clastic sandstone reservoirs from the Penyu Basin and Tenggol Arch area has revealed that the deepest, stratigraphically oldest and potentially overpressured reservoirs are affected by diagenetic alteration of reservoir mineral components. There is a marked discrepancy between measured reservoir temperature and calculated reservoir temperature based on vitrinite reflectance data in several investigated wells. Assuming a relatively constant temperature gradient in the basin during the Pliocene to recent time, quartz cementation started at a paleo-depth of ca. 2000m tvdss or 105°C, and porosity was mostly destroyed at a depth of ca. 3000m tvdss and 130°C. This said, there is a strong stratigraphic correlation between pre-Oligocene sediments with high vitrinite reflectivity readings, and a strongly elevated contemporaneous temperature gradient. Therefore, the scope for deep oil and gas drilling maybe reduced in at least some parts of the basin, where oil is found locked in diagenetically altered pore spaces. In addition, geological data also suggest that the Penyu Basin is very complex and may have stronger affiliation with pull-apart rather than with rift basins.
