Core Subject : Science,
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

Magnetostratigraphy is the element of stratigraphy that deals with the magnetic characteristics of rock units, obtained by measuring the direction and intensity of magnetism in rocks of different ages. The magnetic characteristic most often used, however, is the polarity of magnetic remanence. The polarity is said to be "normal" (north-seeking magnetization gives a northern hemisphere pole, as today) or "reverse" (north-seeking magnetization gives a southern hemisphere pole). The polarity is established from isolating of the primary remanent magnetism of the sample, using paleomagnetic investigation.Magnetostratigraphy defines the sequence of geomagnetic polarity reversals recorded during deposition of a geological formation. This approach can be a very valuable technique for the subsurface correlation of marine and continental sequences and is the only correlation technique which is independent of any facies control. It provides an important complement to biostratigraphy for core correlating and dating. In general the rock magnetic stratigraphy involves the utilization of magnetic properties of sediments and sedimentary rocks as a means of (1) stratigraphic correlation, (2) identification of sediment sources and transport mechanism, (3) characterization/detection of paleoenvironmental change.

Abstract

Attempts have been made to determine the stability of a geomagnetic field for the last 4 Ma of Plio-Pleistocene volcanic rocks from the Bandung area, and it was found that the geomagnetic directions were indicated to be much deflected from the present geomagnetic direction, and in the present study were supported by complementary studies of petrographical and geochemical characteristics leads to a better comprehensive on the variations of the Earth's magnetic field. The result shown that most of K-Ar ages are consistent with obtained magnetic polarity and other stratigraphic indicators. Therefore, an improved chronostratigraphy in this area would be as a standard for correlation, especially to establish the Plio-Pleistocene stratigraphy on the area such like West Java in particular, which is mainly dominated by volcanic origin.
