  1. 1. Evolution of a silicic magma reservoir in the upper crust : Reyðarártindur pluton, Southeast Iceland

    Författare :Emma Rhodes; Steffi Burchardt; Abigail Barker; Charles F. Parker; Alexander Cruden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magma; magma emplacement; magma reservoir; floor subsidence; piecemeal subsidence; granite; pluton; cap-rock; magma mingling; magma plumbing systems; volcanic and igneous plumbing systems; eruption; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Field observations of extinct and exposed magma reservoirs shed light on processes operating in the roots of presently active volcanoes. The Reyðarártindur pluton, Southeast Iceland is an example of a fossil shallow magma reservoir that fed eruptions. LÄS MER

  3. 2. The dynamic emplacement of felsic magma in the upper crust

    Författare :Tobias Mattsson; Steffi Burchardt; Karen Mair; Christoph Breitkreuz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; laccolith; cryptodome; magma emplacement; magma flow; magma rheology; granite; rhyolite; pluton; AMS; XCT; thermobarometry; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : Felsic magma intrudes earth’s upper crust through a variety of mechanisms. Magma intrusion growth and shape have mainly been explained in terms of host rock properties and intrusion depth, while considering the magma as an overpressurised fluid. LÄS MER
