The relevant characteristic of the evolution of the Pacific continental margin of South America during the Mesozoic-Early Cenozoic has been tectonic segmentation. This has controlled succesive episodes of sedimentary accumula, Ition, extrusive and intrusive magmatism and deformation that ocurred at conververgent plate edges. …
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…

Magma generation in arc systems is the most complex phenomenon and history compared to that in other tectonic settings. The magma source/or sources and process/or processes caused the wide geochemical variation of the rocks produced are widely discussed, but still no agreement among the petrologists and geochemists. Indonesia…
Oil & Gas and• coal resources in Indonesia have been known smce the pre• independent era, and up to present-day, they are still mined and considered to be an important fossil energy commodity for several decade in the future. In contrast, oil shale deposits in Indonesia have not been touched for the benefit of f…
