  1. 1. Application of scattered sunlight spectroscopy for quantification of gas emissions from anthropogenic and natural sources

    Författare :Claudia Rivera; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anthropogenic sources; gas emission; volcanoes; sulphur dioxide; DOAS; nitrogen dioxide.; scattered sunlight spectroscopy; natural sources;

    Sammanfattning : Monitoring of gas emissions from natural and anthropogenic sources is of importance due to their negative effects on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. LÄS MER

  7. 5. Magma-Crust Interaction at Subduction Zone Volcanoes

    Författare :Ester M. Jolis; Valentin R Troll; Silvio Mollo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magma-crust interaction; stable isotopes O-C ; radiogenic isotopes Sr-Nd-Pb ; calc-silicate xenoliths; HP-HT experimental petrology; crustal volatiles; Vesuvius; Merapi; Kelut; the Sunda arc; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : The focus of this work is magma-crust interaction processes and associated crustal volatile release in subduction zone volcanoes, drawing on rock, mineral, and gas geochemistry as well as experimental petrology. Understanding the multitude of differentiation processes that modify an original magma during ascent to the surface is vital to unravel the contributions of the various sources that contribute to the final magmas erupted at volcanoes.
