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

Gorontalo Bay exists as one of eastern Indonesia’s mystery basins in terms of its tectonic evolution and stratigraphy. Detailed interpretation of newly acquired regional 2D seismic data provides an understanding of the tectono-stratigraphic evolution of the western part of Gorontalo Bay.The formation of western Gorontalo Bay and adjacent areas is related to thermal subsidence initiated during the Early Miocene, associated with plate tectonic collision in Sulawesi (—23 Ma). This event initiated the development of the fore-arc basin along a NE-SW trending zone of weakness in Oligocene and older basement rocks. The NE-SW trending basin was filled by thick deep marine sediments. Subsidence was interrupted by a later uplifting event along the southeastern margin.Carbonates became dominant in this basin following the formation of a thick carbonate platform. The shallow marine carbonates were developed widely in the basin before rapid subsidence to the present-day deep water (2 km depth). This rapid subsidence is the result of the Celebes Sea subduction and trench rollback during the Pliocene (—5 Ma) to Recent.The results from this study imply that this basin potentially has a petroleum system for future hydrocarbon exploration according to the depositional environments. Hydrocarbon could be sourced from mature deep marine sediments in the basin centre. Mixed grain rocks, fractures and local unconformities within the sedimentary mega sequences potentially form economical stratigraphic plays. These should be the major targets for hydrocarbon exploration in this area.

Abstract

Sulawesi is well known for its complex Cretaceous-Tertiary collisional tectonic history, with a succession of volcanic arc deposits. Numerous publications have appeared on these topics. Also quite a few papers discuss general stratigraphy of areas, but very few papers can be characterized as 'sedimentology papers', i.e. papers documenting and interpreting sedimentary structures, measured sections, current directions, provenance, depositional environments, paleogeography, etc.

Abstract

Sulawesi Sea and its surrounding area is an active tectonic region. Many studies were done to understand the tectonics in this area. For this reason, several seismic vintages were acquired in the Sulawesi Sea (Celebes Sea) area. The seismic lines were published in:1977 by Hinz: single multichannel reflection seismic (MRS) profile1979 by Hamilton: single trace reflection seismic lines1987 by Hinz and 1989 by Fechner: seismic data acquired by SONNE-cruise 49 in Mindanao area, at the eastern end of the Celebes Sea Basin.1994 by Zen and Hinz: seismic data acquired by SONNEcruise 94, sponsored by German institutions.1997, by Beiersdorf et al.: seismic data acquired by SONNE-cruise 98 which also did geological and geochemical investigations.This article shows the seismic expressions in the southern margin of the Sulawesi Sea, which is the subduction zone in the north of Sulawesi North arm and known as North Sulawesi Trench.

Abstract

Barru area comprises four sedimentary sequences that include Cretaceous flysch sediment of Balangbaru Formation in the lower part, overlain by Tertiary terrestrial sediments of Mallawa, shallow-marine redeposited carbonate of Tonasa and volcaniclastics sediment of Camba Formations in the upper part. Three of these sequences show characteristics of deep-marine depositional system that are associated with turbidite – debris flow facies and post-depositional deformation structures. Their occurrences are interpreted to have been controlled by regional tectonics, in particular during the redeposition of the Tonasa Formation carbonates and also the volcaniclastic-epiclastic of the Camba Formation. The difficulties in defining sedimentary basin in this area might possibly be, in part, due to the basin was modified during or after the depositional period. Therefore, it is very hard to trace the basin continuously in only one site.

Abstract

Southern Spain is famous for its beautiful beaches that usually receive a flock of Spanish and European tourists during the summer. The region has Mediterranean climate without much rain but a lot of sunshine for majority of the year. It has mild and wet winter but in some places it can be very dry and has limited vegetation cover only. The climate is a contributing factor to the preservation of spectacular rock outcrops, which provide beautiful landscapes, outstanding scenes, and more importantly, valuable field laboratory to learn sedimentology and stratigraphy. One such region is Almería Province that has several small basins, including the Almería-Níjar Basin.The Almería-Níjar Basin has extensive outcrops of Upper Miocene carbonate complex that lie on the foothill of Sierra Alhamilla and also along the coast. Recently, a group of geoscientists from Repsol visited some of the Upper Miocene carbonate outcrops to see their large scale geometries and then to get a closer look at their lithofacies. The visit was aimed mainly to observe paleomorphology that can be used as analogs for seismic interpretation purpose. The Upper Miocene carbonate outcrops of the Almería-Níjar Basin are unique because their present geometries are still similar to their paleomorphologies during the time of deposition.

Abstract

The offshore margin of West Sulawesi (eastern Makassar Straits) is characterized by an active, Late Miocene/Early Pliocene to present day, NE-SW-trending and NW-verging deepwater fold and thrust belt. The fold and thrust is approximately 250 km long and as much as 75 km wide and consists of an Oligocene to present day succession that was deposited on subsiding, thinned, rifted continental crust and is now deformed by SW-to NE-verging thrust faultrelated folds deformed on multiple detachment layers. Based on the across strike variations in structural style and bathymetry changes, the West Sulawesi fold and thrust belt can be divided into five across-strike main structural domains. From northwest to southeast these are: the abyssal plain, the deformation front, the folded domain, the thrust domain and the inversion domain. The abyssal plain is solely deformed by Pliocene to Pleistocene, low-displacement, planar extensional faults, which are interpreted to be the result of flexural subsidence ahead of the advancing thrust front. The structural styles of the deformation front are strongly controlled by inversion of the Pliocene to Pleistocene extensional faults. Inversion of pre-existing faults controls fault localization and fold vergence, giving rise to complex wedge and triangle zone geometries.The structural styles of the folded and thrust domains are characterized by complex NW- to SE-trending detachment and fault-propagation folds, with multiple detachment levels developed in Oligocene and Miocene mudstones. The inversion domain is the innermost and oldest element of the thrust belt and consists of large anticlines that resulted from reactivation of Paleocene rift structures. The results presented in this work are based on the structural analysis of 3480 km of regional 2D seismic lines.The structural patterns described here have implications for understanding fault-fold geometries and growth in other deepwater fold and thrust belts.
