In the Java sea Tertiary sediments cover a cratonized basement of pretertiary age. Tentative standard sections of the Tertiery sequence employ used stratigraphic nomenclature. Regional lithologic correlation provides a consistenst picture of alternating carbonate and clastic series covered by a clay series. This corelations is substantiated by paleo…
Three first order elements combined to shape southeast Asia. the dextral Ninetyeast shear system the Tethyan shear system, and three elements stem from a single cauese - Expansion of The Rotating earth. Reveal of These three elements restores south-east Asia to its early Mesozoic configuration.
Figure 3, modified from KRTA (1989), shows the Ulumbu geothermal area and its location relative to Ruteng, Heng, Ponggeok and W Kokor. As indiated earlier a reasonable • amount of surface scientificsurvey work has been completed. However, one of the technical philosophies. under…
Natural disasters are the, most serious potential threats to human being and their environments. Japan and Indonesia have the same type of natural hazards because of their similarity in tectonic setting. This was a major factor motivating the establishment of cooperative programs between Japan and Indonesia to understand the natural phenomena and th…
An aapa mire was investigated peat geologically. Based on about 1500 volumentric peat samples, the depth, peat types, degree of decomposition (V. Post's methods), bulk density, water content and shear strength were examined along an 800 m transcet. The calorific value was determined from 58 respresentative peat samples from the same transect, as wel…
Above--ground blomass and primary production values for 40 sites representing 22 virgin mire types which occur in the southern boreal vegetation zone in finland are presenterd. Eight ameliorated sites are included in the material. The biomass ranges between 360 - 20 270 g/m2 and is strongly correlated with stem volume on forested sites. Total annua…
Marine technology is a complex science and Indonesia, needs a realistic strategy for the implementation of the relevant technology. The strategy should be evolutionary and should coincide with a national marine program, and with current prevailing domestic and international conditions. There is no doubt that present day practitioners will influence …
It is known that on the occasions of big eruptions, an enormous volume of earth crust material extrudes to the earth surface in the forms of lava flows and fragmental ejecta. The extrusion of lava is always accompanied by a movement of substances of the earth crust down beneath, resulting in the deformati…
Volcanic hazard mitigation program in Indonesia contitutes volcanic monitoring, hazard map preparation, public education, engineering construction and• public awareness. In the last 200 year, 175 thousand people were killed by volcanic eruption. The number has significantly descreased due to the intensive imple…
Bijih Sulfida Kompleks (BSK) merupakan sumber utama logam dasar di masa depan. Sebagai canto, mineralisasi yang terjadi pada bat.uan-lava dasitis di daerah Bojong Salak Bogar Jawa Barat, menghasilkan bijih timbal dalam bentuk mineral galena b~rsama sfalerit, pirit, kalkopirit, argentit dan kuarsa. Pendeteksian dengan metoda geolistrik menunju…
