1. 1. Characterising volcanic magma plumbing systems : A tool to improve eruption forecasting at hazardous volcanoes

   Författare :David A. Budd; Valentin Troll; Tod Waight; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magma plumbing; oxygen isotopes; thermobarometry; crustal assimilation; Katla; Merapi; Kelud; Toba; volcanic hazards; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : This thesis attempts to develop our understanding of volcanic magma plumbing systems and the magmatic processes that operate within them, such as fractional crystallisation, crustal partial melting, assimilation, and magma mixing. I utilise petrology, rock and mineral geochemistry, and isotope systematics to seek to improve our ability to forecast the eruptive frequency and style of active volcanoes, an aspect often lacking in current volcano monitoring efforts.
