This thesis presents the results of a details trace element and isotope geochemistry study int the magma-genesis of volcanoes in the Adonara-Pantar Section (APS) of the East Sunda Arc in Indonesia, a setting where an oceanic island arc is colling with a passive continental margin.
This study was part of a cooperative project with the Indonesian Institute of Sciences, Bandung, Java, the Michigan Technological University group (W.I Rose, Jr., principle investigator) and the Hawaii Institute of Geophysics, University of Hawaii group (G.P.L. Walker, principle investigator).
Today's continental shelves, such as the one covered by the North Sea, are products of the last post-glacial sea-level rise of the glacial era that began in the Late Pliocene and continued until today. The sedimentary history of shelf seas reflects the changing relationship between tectonic subsidence, sea level oscillations and (hydro-) dynamics processes.
The first detailed tephra statigraphy in order to elucidate the eruptive history of Tangkuban Perahu volcano, West Java, Indonesia is presented as fuller detail as possible. It contains detailed description of outcrops, correlation of reference sections, radiocarbon dating combined with K-Ar data, rigorous measurement of thickness, density, vesicularity, and grain size analyses.
Kelimutu is a stratovolcano that has three crater lakes containing exotic fluids. This study presents the analytical results describing the chemistry of each lake, interprets the chemistries in terms of water-rock interactions and volcanic fluxes, and derives a physical lake model that delineates the parameter-window for volcanic crater lake existence.
This study deals with the massive Elvaberget sulphide deposit, in the southern part of the central skellefte district. The ores as well as the surrounding rocks and alteration zone were studies.
The Tethys Oceans separated the African, Arabian and Indian continents from Eurasia in Mesozoic-Cenozoic times. When the Atlantic Ocean opened, the continents started to converge and the Tethys Oceans gradually began closing.
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…
Mount Merapi, island are volcano located in the center of Java (Indonesia), lies upon the remnents of a volcano older than 400.000 years called Pre-Merapi. Sensu stricto Merapi is a very young volcano characterised by a rapid edification. Its history is divided into four periods (ancient, Middle aged, Recent and Historical Merapi).
The Toba depression in northern Sumatera is a complex structure, formed by repeated episodes of caldera subsidence and resurgence, strongly influenced by regional structure. The Toba depression, and the associated Toba Tuff, a widespread ignimbrite sheet which covers approximately 20.000km, are the result of three major eruptive events.
