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.
This thesis presents the results of a petrological-geochemical and stratigraphic study of the calc-alkaline lava from Santorini, Aegean Sea, Greece. The volcanic complex of Santorini consists of seven eruption centres, of which some have been active contemporaneous.
The transport of chemical elements by uprising magma is one of the fundamental processes by which material is recycled through subduction along convergent plate-boundaries. Obtaining quantitative information on the mass balance of volatile elements is hampered by their complex behavior in magmatic systems.
A Geological study of Mt. Kelut is interisting because no detailed volcanological, seismic, petrologic, or geochemical study has been published for this volcano.
The thesis concerns current, historic and prehistoric volcanism in Indonesia. Investigations have been made on several spatial and temporal scales using a combination of remote sensing, geochemistry and morphological analysis.
