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

Event deposits of some lateral extent as defined here occur almost in all types of sedimentary basins. They reflect either locals, intra-basinal processes, or they are associated with regional or global mechanisms. Some types of event beds, such as sediment gravity flows, sandy and muddy turbidites, are common and usually well preserved. They make up large proportions of basin fills, whereas others (e.g., tsunami deposits and in-situ earthquake structures) appear to be less frequent or rare in the geological record. Volume, frequency, and facies of event deposits are controlled by several processes: pre-event sediment accumulation, triggering and transport mechanism, and mode of final deposition.

Abstract

This overview on event deposits is based on (1) a brief summary on denudation rates in regions of various relief and climate as derived from the suspended and bed loads of river, (2) the fractions of sand and mud present in the filld of various basins, and (3) the mechanisms controlling sediment remobilization.

Abstract

The role of terrestrial sediment supply in basin filling and sequence stratigraphy has been frequently mentioned, but quantitative data have been rarely presented and evaluated.

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

Kuliah yang diberikan Prof. Einsele dihadiri oleh hampir seluruh mahasiswa tingkat akhir jurusan Teknik Geologi, yang berjumlah sekitar 75 orang. Selain itu dihadiri pula oleh Ketua Jurusan dan dosen dari jurusan Teknik Geologi. Adapun waktu pelaksanaannya adalah pada tanggal 12 Desember 1997, jam 10-12, dan judul dari materi yang dibawakan adalah Denudation Accumulation System. Pada intinya kuliah tersebut menjelaskan hubungan antara proses denudasional yang dihitung secara kwantitatif dan membandingkan pengaruhnya terhadap proses dan pengendapan yang terjadi, khususnya pada daerah non-marine. Berbagai contoh, khususnya dari Himalaya ditampilkan melalui visualisasi yang sangat menarik. Selama dan sesudah kuliah tersebut beberapa kali pertanyaan diajukan oleh peserta dan diikuti dengan diskusi menarik. Di antara diskusi itu adalah mengenai pengaruh dari volkanisme dan juga iklim terhadap pengendapan yang terjadi, dan juga komposisi dari material yang dihasilkan. Menurut hemat kami kuliah tersebut sangat bermanfaat di dalam memberikan suatu wawasan baru bagi para mahasiswa dan juga para dosen untuk mendengarkan secara langsung keterangan yang diberikan oleh pakar di bidang sedimentologi ini.Diambil dari surat Dr. Agus Guntoro (dosen Univ. Trisakti) kepada Pengurus FOSI

Abstract

The mid-Cretaceous to Eocene flysch deposits of the Xigaze forearc basin in southern Tibet were investigated in a 120 km segment along the Indus Yarlung suture zone. The basin evolved south of the magnetic arc (Gangdise belt) of the Lhasa block on top of trapped oceanic or transitional crust.
