The change of seasons is most clearly distinguishable in the appearances of mountains. Councurrently with snow-melting, the yellowish green colored sprouts of plants attract our attention and tell us the advent of spring on mountains. And when the leaves change their colour from fresh green to dark green, we are informed that the rainy seasons is over and the summer is setting in.
In 1976, the joint research project of the former Geological Survey of Indonesia and the University of Tokyo started. The subject was "Stratigraphy, paleontology and chronology of the hominid fossil bearing formations in Java". From 1977 to 1979 the project was continued as the Technical Cooperation project CTA-4l which had the objective of strengthening services at the Geolog…
The statocone of Mt. Cemara Lawang is part of The Mt. Bromo-Tengger volcano complex, East Java, Indonesia. Mt. Cemara Lawang is comosed of a sequences of deposits, comprising the big feldspar lava, andesite lava, phreatomagmatic ash fall, phreatic, basalt lava, basaltic andesite lava, andesite lava, alternating layers of pyroclastic fall and flow and the brown ash fall deposits from the oldest …
The late Mesozoic and Cenozoic convergence between Europe and Africa led to the Alpine mountain belt. In this thesis we will focus on the Aegean segment of this belt.
A I'heure actuelle, I'Indonesie possede 129 volcans en activite, que se succedent depuis I'ile de Sumatra jusqu'a I'ile de Sulawesi et a la mer de Banda.
Mt. Semeru volcanic complex is basalt-andesite composite volcano in East Java, Indonesia. The structural geology of study area is indicated by faults or structural trends and negative volcanic landforms such as calderas, maars, craters and escarpments.
Maksud dari penyusunan tesis ini adalah mendudukan batuan Komplek Gunungapi Ciremai dan sekitarnya, dalam ruang dan waktu yang sebenarnya, guna membuat hipotesa daerah yang berpotensi terkena bahaya akibat letusan Gunungapi Ciremai, berdaarkan urutan batuannya.
Daerah penyelidikan merupakan bagian dari graben Kerinci yang mempunyai arah baratlau-tenggara, sejajar dengan arah memanjang pengunungan Baeisan. Satuan ignimbrit diperkirakan berumur Eosen. Aktivitasnya mempunya hubungan yang erat denga gerak-gerak vertikal.

This thesis presents the results of a geochemical study of the Banda Arc (East Indonesia) where magma genesis is influenced by subducted source components that are controlled by an active arc-continent collision. The main objective of this study is to investigate the role of subducted continental material on the magma genesis using isotopic and chemical compositions of samples from volcanoes an…
