Geologic Significance of Granitic Fragment Found from Pumice flow of 1883 Eru…

Pumice flow of the 1883 Krakatau eruption occurs It at Small Rakata, Rakata and Sertung Islands, those which roughly correspond to the wall of Krakatau caldera, Indonesia. significantly differs in both mineral and chemical compositions against any other volcanic rock or ejecta of the Krakatau Group, those of which belong to Miyashiro's (1974) tholeiitic series. Meanwhile, lithic fragments of gr…

Geological Investigation Of The Recent Damage In The Sluice Of The Kawah Idjen

Under commission of the Director of State's Enterprises ddo. 6 March 1917 No. 801/M the author was instructed to leave for the Residency of Besuki in order to investigate the nature of the youngest slumping's in the Kawah Idjen, and to give advice to the local irrigation- authorities in accordance with the result of the investigation.

Volcanoes & Earthquakes Geologic Violence

The most fundamental part of our environment is the earth on which we live and with which we have the closest contact. This is the realm of geology, the science of the earth. The materials of the solid earth – the rocks, their structure, their alteration by geologic processes, the fossil remains of ancient life in the rock formations – these are the tools the geologist uses to reconstruct t…

There are various epigenetic mineralization types hosted by sedimentary rocks, one of them is recognized as Skarn Deposits. The Skarn (Au-Ag,Cu-Pb-Zn-Mn) type deposits are distributed in almost the whole Indonesia Island Arcs with the exception MOLLUCAS Islands. Nowdays the well known Cu-Au skarn type deposit found in Indonesia is occured in ERTSBERG, West Irian. The total …

The Evolving Anatomy of a Collapsing Orogen

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.

Volcanology and Petrology of MT.Semeru Volcanic Complex,East Java - Indonesia

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.

Petrological Study on Boring Cores in Izu-Oshima Volcano, Japan, during the p…

One km-deep scientific drilling within the summit caldera at Izu-Oshima Volcano, which was done for grophysical observation well by ERI in 1996-1998, penetrating the bottom of the volcano (around 40ka), provides me an excellent opportunity to investigate temporal and chemical evolution of basaltic volcano.

The Late Quaternary Evolution of The Bandung Basin, West-Java, Indonesia

This study concern the quaternary geology, geomorphology and sedimentology of the intramontane Bandung basin, West - Java, Indonesia. A comprehensive analysis of the sequence of lacustrine, alluvial and volcaniclastic sediments in the basin form the basis for a reconsstrution of the Late Quanternary geologic and morphologic evolution of the Bandung basin area and for an evaluation of the geolog…
