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

Turbidite sandstone can form important reservoir rocks. Some giant oil fields with recognized ultimate recoveries larger than 500 million barrels have been found in turbidite deposits. Some major reservoir units in the North Sea Basin are interpreted as multiple stacked submarine lobes with little evidence of channeling. Other giant turbidite reservoirs were also found in the US and other fields in the world.

Abstract

Quaternary deposits in Borneo are commonly not assigned to any formation or group and are usually not studied in great detail but are important for understanding of the Pleistocene to Holocene climate and drainage evolution. This study presents a detrital zircon provenance analysis of two possible (Plio-) Pleistocene fluvial deposits in West Sarawak, indicating two very different source areas and paleo-river drainages. Those paleo-rivers resemble the present-day drainage but show much higher energy level deposits associated with higher sedimentation rates possibly as a function of (Plio-) Pleistocene climate and hinterland exposure. The deposits at Kampung Jangkar in western West Sarawak were entirely sourced by the uplifted Pueh batholith. In contrast, sediments in Petra Jaya district (northern Kuching city) were sourced by recycling of the Kayan Sandstone near the Bungo Range in the area of the town Bau. The Petra Jaya sediments have abundant Pliocene and some Late Miocene zircons. The Niut Volcanics south of West Sarawak are of this age, but are basic and could not yield significant zircons. It is therefore concluded that zircons came from acid igneous rocks of Pliocene age, as well as the Kayan Sandstone and Middle Miocene Bau Suite igneous rocks, where they formed a highland in the Bau-Bungo Range region which has been entirely removed by erosion.

Abstract

In May 2012, Bailey and Jones published an article titled “Micropalaeontology Under Threat!” in Geoscientist Online Special, which attracted a number of readers’ attention. This topic was discussed further in the Sedimentology and Paleontology Linked-in group. The article describes trends in the United Kingdom, but these are similar in many other countries. It observed how since the 1980's the employment opportunities for micropaleontologists decreased as a result of downsizing by oil companies, how training opportunities decreased due to reduction in the number of universities teaching micropaleontology courses, and how retirements of an aging population of biostratigraphers may soon lead to a shortage in experienced biostratigraphers.To understand the situation in Indonesia, the topic was launched in IAGI-net. A simple survey was run on Facebook to involve students. This article summarizes the discussion and survey to provide a general understanding and quick overview on how micropaleontological education is conducted in Indonesia.

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.
The Himalaya-Bengal Fan Denudation-Accumulation System during the Past 20 Ma G. Einsele; L. Ratschbacher; A. Wertzel

Abstract

Mass balances for both denudation in the Himalayas and sediment accumulation in the Subhimalayan basins, including the Bengal deep-sea fan but excluding the Indus fan, yield 7.1 x 10^6 km2 and 7.4 x 10^6 km2 (s +/- 20%), rock of 2.75 g/cm3 density, respectively, for the past 20 Ma. Coarsening and increased sediment accumulation rates in the foreland basin and in the Bengal foredeep indicate accentuated tectonic activity and unroofing in the Himalayas since that time. The sediment volume includes ≥ 1 x 10^6 km3 of Neogene Bengal fan sediment that was lost via the Nicobar fan to the Sunda accretionary wedge. In addition, the Indian peninsular rivers contributed about c. 0.6 x 10^6 km3 of solid load to the basins. Average denudation during the past 20 Ma, as derived from geothermobarometric data and restored cross sections, occurred most rapidly along the High Himalayan crystalline chain (vertical unroofing, c. 1000 m/Ma; northward lateral retreat of southern Himalayan slope, exposed to monsoonal rain, ≥ 3.5 km/Ma), and much slower in the Tehtyan sedimentary zones to the north (average 150 m/Ma). The solute loads of the modern Himalayan rivers indicate a mean chemical denudation rate of 17 m/Ma. The distinct decrease in sediment accumulation on the outer Bengal fan between about 7 and 1 Ma (in contrast to the Indus fan) is probably caused by exogenic factors rather than by a significant decline in tectonic activity. Pre-20 Ma sediments in the Subhimalayan basins were derived mainly from the southern margin of the Tibet plateau or form sources outside the study area.

Abstract

Kali Banyumeneng is located in Mranggen, Demak (Central Java province). The studied outcrop is located approximately 11.25 km to the SE of Semarang city and at the geographic coordinate of 100° 28’ 59.65” E and 7° 02’ 43.45” S.The study area is geologically located in Kendeng Zone, which is also often referred as Kendeng Mountains, an east-west trending anticlinorium in the northern part of Java. The northern border of the Kendeng Zone is Randublatung Depression, while the southern border comprises a line of volcanoes called Solo Zone. Kendeng zone is a continuation of the Northern Mountains Serayu Zone that developed in Central Java. The Salatiga section of the Kendeng zone extends towards the east to Mojokerto and plunges under the Brantas river. The continuation of these mountains can still be tracked under the Madura Strait.Van Bemmelen (1949) subdivided Kendeng Mountains into 3 parts that consist of the western part, which lies between Mt. Ungaran and Solo (north Ngawi); the central part that lies between Solo and Jombang and the eastern part that extends from east Jombang to Brantas River Delta and continuously to Madura Bay. The study area occurs in the western Kendeng Zone. Previous work shows that the study area consists of two lithostratigraphic units called Kerek and Kalibeng Formations. Kerek Formation consists of interbedded sandstones, claystones, and sandy limestones with observed sedimentary structures such as graded bedding, ripple mark and convolute. Kalibeng Formation is subdivided into lower and upper parts. The lower part of Kalibeng Formation consists of sandstones that shows turbiditic nature. The upper part of Kalibeng Formation is composed of breccias with fragments formed by limestone. The Upper Kalibeng Formation also contains forams, molluscs, corals and algae and it shows a bedding structure.Observations were carried out to determine the depositional environment model of Kali Banyumeneng area based on lithology, sedimentary structures and fossils.

Abstract

In February 2015, the Padjadjaran University (Universitas Padjadjaran - UNPAD) Sedimentology Research Team held an excursion to Kepulauan Seribu (Thousand Islands) in the Java Sea, offshore northern Jakarta. The trip was not just about having fun and luxurious escape, but more importantly it was to enjoy the adventure with pocket-friendly expenses and gain new geological knowledge directly from the field. For a team that comprises young geologists, every side of the earth is interesting especially in relatively remote areas where earth processes’ imprints are preserved better; the geological phenomena can be traced back to its formation in the past and deduced of the impact in the future.
