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

Conglomerate beds with generally rounded to subrounded coal fragments are common in channel deposit facies in Samarinda Region (East Kalimantan), beds occur as interbeds within Balikpapan Formation. The coal fragments are possible transported and sedimented wood cuts or transported coal fragments from an older coal seam. This study compares the bed thickness with the diameter of the coal fragments and the other fragments. The cross plot of the bed thickness and grain size gives a better understanding of the sedimentation processes. Anomaly diameter of the coal fragments indicated wood fragments origin coals, also showed by the texture, the gradual changes of colour and the shape of the fragments. Small fragments (less than 1 cm) is hard to distinguish due to unclear texture and shape. There are two possibilities of the small coal fragments origins, coal clastics or small high density wood cuts. Coal fragments characteristics in conglomerate beds and typical Gp and Sp facies characteristics show that the coal fragment were deposited in a point bar controlled by a flooding process and the Gms facies was deposited in proximal channels.

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

The tectonic evolution of Sulawesi is complex it is situated in the triple junction of the Indo-Australian, Eurasian and Pacific Plates. The late Cretaceous to Neogene history has resulted in considerable changes in the tectonic setting attributable to plate motions. Southern Sulawesi was a fore-arc region in the late Cretaceous with the deposition of a deep marine siliciclastic sequence; this evolved into a back arc setting in the Eocene, and a thick succession of volcanics of both acidic and basin composition were developed from Eocene to lower Miocene times. Following this volcanic phase carbonate sedimentation dominated in the Middle Miocene. This study documents the tectonic control on carbonate facies distribution (Tacipi and Walanae Formations) in the Middle Miocene-Lower Pliocene of southern Sulawesi.

Abstract

Field trip yang diselenggarakan dalam rangka IPA Convention 1996, diselenggarakan di Bengkulu. Field trip yang disertai oleh 30 orang ini dipimpin oleh Bpk Berlian dan Sudarman dari Lemigas. Meskipun field trip ini dilaksanakan hampir satu tahun yang lalu, namun sayang rasanya jika hanya dinikmati oleh sedikit orang saja. Oleh karena itu kami tulis di sini agar lebih banyak orang yang dapat menikmatinya.
