Abstract

The use of microfossils in the dating of sedimentary rocks is commonplace, and well documented. However, the use of these fossils, particularly benthic foraminifera, in the interpretation of depositional environments has received less attention. A series of mudstone samples collected from five formations outcropping in eastern Sabah, NE Borneo, ranging in age from Eocene to Pliocene in age, has yielded more than 80 species of calcareous and agglutinated foraminifera. These have been interpreted to give both stratigraphical and depositional information.The microfossil assemblages are interpreted to represent conditions ranging from those inhabiting mangroves, very shallow marine to paralic coastal settings, through to open marine, relatively anoxic settings. These interpretations are supported by the interpreted sedimentology of measured outcrop sections. The preservation, size of individual tests, species diversity and diagenetic signatures have been combined to provide a detailed picture of conditions extant at the seabed during deposition of these sediments. This includes oxygen and energy levels, as well as evidence of post mortem dissolution. Around 60% of the samples yielded a very limited fauna, or were barren. Among the assemblages identified are deep marine 'flysch-type faunas' that are also comparable to the Agua Salada Fauna of Northern Venezuela.The synthesis of foraminiferal and sedimentological data provides a powerful tool in identifying depositional environments in seemingly homogenous mudstone beds. Hence it can be used as a correlation tool. Through applying the process described here to hydrocarbon exploration, it is possible to extrapolate additional information on depositional settings from core, and hence provide sequence stratigraphic architectural trends. These can be used to predict source rock distribution. This approach may also be applied to cuttings data in the absence of well logs or core.

Abstract

In Indonesia, nannofosils are commonly used for age estimation on Miocene marine sediment, but they are rarely performed on Quaternary sediment. This paper introduces two nannofossil biozones, Martini (1971) and Backman et al. (2012) and the comparison between the two biozones. An uninterrupted interval of marine sediments was described and picked for quantitative nannoplankton analysis. The samples were taken from Ledok Formation to Lidah Formation in Pati Region, Northeast Java Basin. The samples were prepared by quick smear slides method and and analyzed by quantitative field of view method. Martini (1971) biozone can be used to subdivide the Late Miocene–Pleistocene sediments into 5 biozones, but Backman et al. (2012) can be used to classify the same sediments into 8 biozones. The biozone subdivision from Backman et al. (2012) is more detailed than that of Martini (1971) because an updated dating and biozone in the three new dating zone data.

Abstract

The islands of Biak and Supiori, situated in the Bird’s Head region of New Guinea, comprise predominantly Neogene age carbonate units that extend offshore into the adjacent Biak Basin. Unusual geomorphologic features including pockmarks, headless canyons and semi-circular collapse structures identified in multibeam bathymetric imagery occur on the southern margin of the Biak Basin. These features have a bathymetric expression distinct from strike-slip faults of the Biak Fault Zone which bound the eastern margin of the basin. The Biak Fault Zone comprises several seismically active, segmented and parallel fault strands. Seismicity along the Biak Fault Zone is responsible for the shedding of mass transport deposits into the basin, however these are absent from the geomorphologic features along the southern margin of the basin. Instead, these features appear isolated and unrelated to activity of the Biak Fault Zone and are interpreted to have formed as a result of ‘spring sapping’ by submarine aquifers. Rapid uplift during the Pliocene caused exposure and karstification of carbonates from onshore Biak which extend into the offshore Biak Basin, providing conduits for a freshwater lens to develop within older Miocene strata. Diagenetic cement textures and fabrics indicate that many Miocene carbonates were subjected to meteoric diagenesis within freshwater aquifers that overprinted burial cements. This is supported by stable isotope analyses of diagenetic cements which record negative δ18O values.

Abstract

West Crocker Formation is located in Northwest Sabah of Borneo (Kalimantan) Island. This formation was deposited during Late Palaeogene (Oligocene) and is undoubtedly the best exposed example of a classic submarine fan system in the Asian region.A field visit had been done in August 1999 to view the outcrops of West Crocker Formation. These have been well-exposed in Kota Kinabalu and its vicinity. In fact, the field trip had been held to also visit other Paleogene and younger Neogene rocks in Labuan Island and Brunei areas. In this text, only the outcrops of West Crocker Formation will be discussed.

Abstract

Kendeng Zone is well known as the main depocenter in the North East Java Basin. It developed as a back arc basin related to Oligo-Miocene volcanic arc and was subsequently filled with thick pelagic and volcanogenic sediments.This article emphasizes on determination of facies, geometry and distribution of sand bodies within the Miocene Kerek Formation that comprises the western Kendeng Zone. Sedimentological logs and rock samples were collected from outcrop data along river traverses in the study area. The samples were described and characterized by using petrography, paleontology and sedimentology analyses. Three depositional facies were identified, which consist of massive sandstone of submarine lower fan, a lobe of submarine lower fan and pelagic mud deposits.Statistical analysis was also used to characterize and describe identified depositional facies within the Kerek Formation. Statistically, the geometry consists of (1) pebbly massive sandstones of submarine lower fan (mean distribution of sands bodies: 4.58 km, mean thickness: 0.6 m, length from 3D modeling: 1.58 km); (2) sandstone sheets of submarine lower fan (mean distribution of sands bodies: 2.85 km, mean thickness: 0.08 m, length from 3D fence diagram: 1.26 km); (3) pelagic mud, which is composed solely of thick mudstone lithofacies. In term of reservoir potential, the massive sandstones that have significant amount of porosity would be considered as having the highest potential.

Abstract

The Mahakam River is located in East Kalimantan (Borneo), Indonesia, recognized as a good example of a mixed fluvial and tide-dominated delta. The river supplies sediments to Makassar Strait basin and has built a major delta systems at its mouth. The delta plain consists of predominantly fine grained sediments, provided by the fluvial system.The Mahakam river drainage basin drains the Kutai Tertiary basin. The drainage basin is bounded by the Tertiary uplift in the east, Mangkaliat ridge in the north, and the Kuching High in the west. The northeast-southwest Tertiary ridges separate the drainage basin from the sea. Centripetal, trellis and deranged drainage patterns occur in the basin.Erosion processes are intensive in this area, due to the tropical heavy rain fall. The fluvial system is also influenced by vegetation, evapotransporation rate and tide. The Kutai Lakes Complex occurrence in the drainage basin and the high evapotransporation potential affects the sediment supply for the Mahakam Delta. Sediments supplied by the basin consist of predominantly quartz sandstone, shale and organic material. Sedimentological processes in the fluvial system are very active. The Kutai Lakes and the high evapotransporation potential of the area influence the sediment supply for the Mahakam Delta.

Abstract

This is a brief note of our visit to Solok, Sawahlunto area, Ombilin Basin on November 8, 2008 for the purpose of broadening our knowledge on non-marine depositional sequence and its relationship to the development of hydrocarbon petroleum system in the region. Exposure of the outcrops is excellent in the form of accessibility and vertical extent of the stacked sequences.Unfortunately, as the time was limited, there was no opportunity to conduct sufficient detailed description of the outcrops. However, several notes of broad observation of the outcrops were made. Part of them is discussed in this paper.A total of eight (8) locations (=STA) were visited during this half-day reconnaissance trip. The traverse began from Solok using a car towards the northeast to locations 1 to 8 following the existing main road to Sawahlunto. The outcrops are easilyaccessed and visible from the main road. Some of the outcrops are located immediately on the edge of the road.

Abstract

The evolutionary series from Heterostegina (Vlerkina), through Tansinhokella to Spiroclypeus is reviewed. Both previously unpublished work (Muhar, 1956) and new field data is used to support the hypothesis that this evolutionary development can be observed twice in the fossil record. The first lineage became extinct at the Oligocene- Eocene boundary, and then the same morphologies re-appeared in the middle and later Oligocene. Both the negative evidence (absence) of Early Oligocene [Tc / Td Letter Stage] records, and the positive evidence of a gradual evolutionary series in Oligocene times, are discussed. At the moment there is no reliable way to distinguish the Late Eocene and later Oligocene tests, so the same generic name has to be applied to each occurrence, even though they are separated in time. This leads to the unusual situation that all three genera have to be reported as having two evolution and two extinction datums.The later Oligocene transition of Tansinhokella into Spiroclypeus is observed to be more gradual than the morphological criteria used to separate these genera in 1991 (Banner and Hodgkinson), but the two names are retained for end members of a gradual series with a distinct stratigraphic record.The hypothesis of iterative evolution was based on work in Java, and it was predicted that the other areas in Asia would preserve the same evolutionary pattern in the stratigraphic record. This work shows that the second evolutionary development of Tansinhokella and Spiroclypeus was at the same time in three geographically separate areas, the most reasonable explanation for which is iterative evolution, rather than ecophenotypic fluctuations or faunal migrations.The importance of Tansinhokella in the biostratigraphic subdivision of Letter Stage Te is highlighted.
