  1. 1. Constraining Crustal Volatile Release in Magmatic Conduits by Synchrotron X-ray μ-CT

    University essay from Berggrundsgeologi

    Author : Sylvia Berg; [2011]
    Keywords : xenoliths; crustal gases; synchrotron X-ray μ-CT; 3D-bubble networks; gas migration; magmatic volatile budget; explosive eruption;

    Abstract : Magma-crust interaction in magma reservoirs and conduits is a crucial process during magma evolution and ascent. This interaction is recorded by crustal xenoliths that frequently show partial melting, inflation and disintegration textures. READ MORE

  3. 2. Disintegration and Devolatilisation of Sandstone Xenolith in Magmatic Conduits: an Experimental Approach

    University essay from Berggrundsgeologi

    Author : Sylvia Berg; [2010]
    Keywords : xenolith; melting; bubbles; gas migration; crustal volatiles; magma-crust interaction; magma volatile budget; explosive eruption;

    Abstract : Xenoliths preserve evidence of magma-crust interactions in magmatic reservoirs and conduits. They reveal processes of partial melting of country rock, and disintegration into magma. Widespread evidence for frothy xenoliths in volcanic deposits exists, and these evidently indicate processes of gas liberation, bubble nucleation and bubble growth. READ MORE
