IJOG : Indonesian Journal on Geoscience
Published by Geological Agency of Indonesia

Core Subject : Science,
Earth & Planetary Sciences
The spirit to improve the journal to be more credible is increasing, and in 2012 it invited earth scientists in East and Southeast Asia as well as some western countries to join the journal for the editor positions in the Indonesia Journal of Geology. This is also to realize our present goal to internationalize the journal, The Indonesian Journal on Geoscience, which is open for papers of geology, geophysics, geochemistry, geodetics, geography, and soil science. This new born journal is expected to be published three times a year. As an international publication, of course it must all be written in an international language, in this case English. This adds difficulties to the effort to obtain good papers in English to publish although the credit points that an author will get are much higher.

Abstract

http://dx.doi.org/10.17014/ijog.vol1no1.20065aThe Tigapuluh Mountain located in southeast corner of the Riau Province, is a part of the southern margin of the Central Sumatera Basin, one of the biggest hydrocarbon producing basin in Indonesia. The hydrocarbon source rock potential is a fine grained clastics within the Late Eocene Kelesa and Oligocene Lakat Formations. The Kelesa Formation source rock has a TOC value of 2.31–9.63%, with hydrocarbon content of a good to excellent categories (6.23–70.72 kg/ton rock), whereas the Lakat Formation has a TOC value of 0.67–3.46%, with hydrocarbon content of a poor to excellent categories (1.21–37.38 kg/ton rock). Source rock thermal maturation of the Kelesa Formation ranges from a late immature to early mature, with kerogen type of I and II, whereas the Lakat Formation ranges from a late immature, with kerogen type of I, II, and III. Diagenetic stage of the hydrocarbon source rock of the Kelesa Formation is included to Mudrock Stage II which is equivalent to a mesogenetic mature “A”. This diagenetic proccess was due to the burial history with the depth of up to 3000 m, resulted in a paleotemperature of 95C. The Lakat Formation is, however, included to Mudrock Stage I equivalent to the mesogenetic immature level. Burial history which occurred at the paleo temperature up to 65C, with the depth of burial up to 1500 m, led to the diagenetic process.

Abstract

http://dx.doi.org/10.17014/ijog.vol1no1.20066aThe eruption of Tambora volcano on the island of Sumbawa in 1815 is generally considered as the largest and the most violent volcanic event in recorded history. The cataclysmic eruption occurred on 11 April 1815 was initiated by Plinian eruption type on 5 April and killed more than 90,000 people on Sumbawa and nearby Lombok. The type plinian eruptions occurred twice and ejected gray pumice and ash, to form stratified deposits as thick as 40-150 cm on the slopes and mostly distributed over the district west of the volcano. Following this, at about 7 pm, on 11 April the first pyroclastic surge was generated and progressively became greater extending to almost whole direction, mainly to the north, west, and south districts from the eruption center. The deadliest volcanic eruption buried ancient villages by pyroclastic surge and flow deposits in almost intact state, thus preserving important archaeological evidence for the period. High preservation in relatively stable conditions and known date of the eruptions provide approximate dating for the archaeological remains. Archaeological excavations on the site uncovered a variety of remains were relieved by ground penetrating radar (GPR) to map structural remains of the ancient villages under the pyroclastic surge and flow deposits. These traverses showed that GPR could define structures as deep as 10 m (velocity 0.090 m/ns) and could accurately map the thickness of the stratified volcanic deposits in the Tambora village area.
