Common Trace Fossils of the Deltaic and Turbidite Outcrops in Kutei Basin, East Kalimantan: A Field Note Herman Darman
Berita Sedimentologi Vol 19, No 1 (2004)
Publisher : Ikatan Ahli Geologi Indonesia

The Kutei Basin is dominantly clastic Tertiary basin bounded by basement uplifts in the north, west and east. The basin is open towards the Makassar Strait in the east. The Paleogene sections of the basin were outcropped at the basin margin. In Muara Wahau area in the northern part of the basin, this section is dominated by turbidites with slump features. High variety and low quantity of trace fossils are found in the thin-bedded turbidites, mostly grazing structures and the assemblage suggest Nereites ichnofacies. The trace fossil associations suggest ocean basin environment of deposition and the biostratigraphic analysis indicates bathyal to abyssal zone. At the centre of the basin the Neogene deltaic sections cropped well in Samarinda area. there is high quantity of trace fossils but low in variety. Dwelling vertical burrows of Skolithos ichnofacies are dominant in this section. The trace fossil association suggests tidal zone with inner to outer neritic biostratigraphic environment.

Introduction to Cenozoic Biostratigraphy of Indonesia-SE Asia J.T. (Han) van Gorsel; Peter Lunt; Robert Morley
Berita Sedimentologi Vol 29, No 1 (2014)
Publisher : Ikatan Ahli Geologi Indonesia

An overview is presented of the current 'tools' of biostratigraphy and biofacies interpretation, as applied in the Cenozoic basins of Indonesia and Southeast Asia. We discuss previous work and historic developments of the biozonations and biofacies significance of the principal microfossil groups used in the region (foraminifera, calcareous nannofossils, palynology) and present the latest zonation charts and tables of key references. Brief reviews of work done on ostracodes, diatoms and radiolaria are also included.

Why don’t we look to the west? Widianto, Harry; Noerwidi, Sofwan
Berita Sedimentologi Vol 47, No 3 (2021)
Publisher : Ikatan Ahli Geologi Indonesia

Paleontological data indicate that the beginning of Java Island’s human habitation took place at the Plio-Pleistocene boundary, around 2.4 Ma, along with uplift process and glacial-interglacial cycles. However, the oldest Homo erectus fossil was mainly found in the eastern part of Java Island where age-dating indicates that they were from ca. 1.5 Ma, especially along the riverbanks of Bengawan Solo and Brantas, such as Perning, Sangiran, Kedungbrubus, Ngandong, Ngawi, Trinil, and Sambungmacan.Recently, Pleistocene sites were discovered from the western part of Java, e.g., Rancah (Ciamis), Semedo (Tegal), and Bumiayu (Brebes) with their archeological, paleontological, and paleoanthropological potentials. This work will present the significance of the potential, especially paleoanthropological data from the new sites, and their implications to the Quaternary prehistory research strategies determination in the future.We present new geological, archeological, paleontological, and paleoanthropological evidence from those mentioned sites. The result shows that the distribution of Homo erectus were extended to the western part of Java, between 1.8-1.7 Ma, older than the oldest previous finding of Homo erectus from Perning and Sangiran. This finding suggests a new window of the human arrival on this island. So, why don’t we look to the west? Intensive research in the future should be addressed to the western part of Java Island.

Deep-water Gulf of Mexico Basin: An Overview of Its Petroleum Exploration F. Hasan Sidi
Berita Sedimentologi Vol 15, No 1 (2001)
Publisher : Ikatan Ahli Geologi Indonesia

The Gulf of Mexico Basin is one of the most prolific petroleum provinces in the world. The present-day deepwater portion of the Guld of Mexico has been explored since mid 1970's. Exploration and development activities have increased significantly during the last couples of years. Since then, over 600 wildcat wells have been drilled in the various deep-water plays in the basin, and industry has leased in excess of 4300 lease blocks covering a cumulative area of more than 38,700 square miles. This activity has been caused by several factors including significant discoveries in deep-water, outstanding reservoir performance in some these discoveries, innovative production techniques, and new Federal royalty relief.There have been 121 discoveries made in the province during the period from 1975 to the end of 1998 with the mean size of these discoveries is 96.5 MMBOE and the largest field found to date is Mars (720 MMBOE). Despite the abundance of drilling and leasing in the basin, some deepwater Gulf of Mexico plays are still in the unproven stage.

Cenozoic Stratigraphy of the East Java Forearc A.M. Surya Nugraha; Robert Hall
Berita Sedimentologi Vol 26, No 1 (2013)
Publisher : Ikatan Ahli Geologi Indonesia

The study area is located in the offshore SE Java and is situated at the southeast edge of the Eurasian plate, known as Sundaland. Sundaland is the continental core of SE Asia and was constructed by amalgamation of continental blocks during the Mesozoic. The East Java Forearc is a relatively unexplored area and the basement has long been considered to be Cretaceous arc and ophiolitic-accretionary complexes. But now there is increasing evidence for continental crust beneath the East Java Sea, and the southern part of East Java.This article presents the findings of an MSc study (Nugraha, 2010) and a geological history presented in an IPA paper (Nugraha and Hall, 2012). New seismic lines south of Java have imaged a deep stratified sequence which is restricted to East Java and is absent beneath the West Java forearc. Main datasets were provided by TGS, comprising three long-offset 2D-seismic datasets (SJR-9, SJR-10, and SJI-10). These data consist of thirty-seven 2D marine seismic lines across the Java forearc with a total of 8266 km survey length. Previously published seismic data (Kopp et al., 2006) were limited to shallow imaging 4-streamer seismic sections.

Book Review: Mesozoic Geology and Paleontology of Misool Archipelago, Eastern Indonesia Herman Darman
Berita Sedimentologi Vol 31, No 1 (2014)
Publisher : Ikatan Ahli Geologi Indonesia

Scientific publications on the Mesozoic of Eastern Indonesia are very rare. This region is relatively remote and accesses to outcrops are generally difficult. Recent publications are predominantly published by petroleum companies based on their subsurface data. It is important to integrate subsurface and outcrops to understand the geology of the area. Hasibuan’s research on becomes important piece of information because he worked entirely based on outcrop data.

Indonesian Marine Geology Research Vessels: Their Capacity and Activity Ai Yuningsih; Wahyu Pandoe; Herman Darman
Berita Sedimentologi Vol 33, No 1 (2015)
Publisher : Ikatan Ahli Geologi Indonesia

About two thirds of Indonesian territory is covered by sea, below which there is little-documented and fascinating geological features which require study. Observing and understanding this geology is obviously technically more difficult than for the onshore. Thus, knowledge of the submarine geology relies on research and commercial ships.The marine geology of Indonesia has been studied since the 18th century. Two French ships called Boudeuse and Etoile, and led by De Bougainville sailed to collect data in 1768. Since then many other research vessels came and were run by researchers from the UK, Austria, the Netherlands, USA, Germany and Japan. In late 1980s Indonesia bought its own research vessel, Baruna Jaya 1, and since then has built its own fleet of research vessels.

The South China Sea: Sub-basins, Regional Unconformities and Uplift of the Peripheral Mountain Ranges Since the Eocene Franz L. Kessler; John Jong
Berita Sedimentologi Vol 35, No 1 (2016)
Publisher : Ikatan Ahli Geologi Indonesia

This paper reviews the complex interaction of basin subsidence, erosion and uplift of mountain ranges that enclose the South China Sea (SCS). We found that recent uplift is a feature occurring dominantly at the fringes of the Sundaland Plate, around Sumatra/Java, Borneo, the Philippines and Taiwan. More significantly, there is a positive age correlation between regional unconformities, formation of oceanic crust and uplift of the peripheral mountain ranges. However, the magnitude of erosion related to each major unconformity can vary regionally, and could partly be subjected to climatic influence. The oldest truly regional unconformity recognizable is of very Late Oligocene age, and acts as an angular unconformity in Sabah, Sarawak, and the Malay/Penyu Basins (at Base ‘K’ level), at or very close to the base of the Miocene sedimentary package. We call this unconformity the Base Miocene Unconformity (BMU). Other than the BMU, the widely-known seismic event called the Mid-Miocene Unconformity (MMU) could be correlated with the end of proto-SCS spreading, and uplift may have occurred only in segments of the SCS, in particular at the southern fringe. The Late Miocene Shallow Regional Unconformity (SRU) points to a short compressive pulse that affected mainly areas of Sabah and Sarawak. The more recent Intra- Pliocene unconformity (IPU), commonly forming the base of some uplifted coastal terraces can be seen in particular in the south and eastern parts of the SCS, and correlates with uplift of areas such as NW Borneo and Taiwan. The event is a likely consequence of the Taiwan collision interplayed with the docking of the Philippines Plate in the Early Pliocene with NW Borneo at the Palawan/Philippines Margin. The Malay, Penyu, Natuna Basins and Vietnam Margin are predominantly Oligocene to Lower Miocene fills, whereas the NW Borneo Foredeep/Palawan Trough, deepwater Nam Con Son Basin and the Bunguran Trough have predominantly a Neogene fill.This observation points to a reduced extensional regime if compared with the south-eastern margin, where fault activity continued to the Mid/Late Miocene. The compiled uplift data in the surroundings of the SCS, as well as the presence of seismically mapped regional unconformities suggest that the greater Sundaland Plate has seen a number of extensions and compression/inversion/rotation phases; however there appears to be no positive evidence for the presence of microplates and/or subduction during the Oligocene/Miocene. In summary, crustal stretching, uplift and the resulting unconformities can be compared to different instruments of an orchestra playing individually; no harmonic tune can be achieved and there is little merit in looking at each contributing factor in isolation.
