The Mediterranean is a region of transition between the sub-oceanic, cool temperate zone of Europe, and the high-pressure, aird subtropics of North Africa straddling the pressure systems of the Atlantic and the monsoon climates of the Indian subcontinent and East Africa.
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.
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.
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.
