    • In situ observation of the percolation threshold in multiphase magma analogues 

      Colombier, M.ORCIDiD; Wadsworth, F. B.; Scheu, B.ORCIDiD; Vasseur, J.ORCIDiD; Dobson, K. J.; Cáceres, F.ORCIDiD; Allabar, A.ORCIDiD; Marone, F.; Schlepütz, C. M.; Dingwell, D. B.ORCIDiD (Bulletin of Volcanology, 2020-03-04)
      Magmas vesiculate during ascent, producing complex interconnected pore networks, which can act as outgassing pathways and then deflate or compact to volcanic plugs. Similarly, in-conduit fragmentation events during ...

    • Vesicle shrinkage in hydrous phonolitic melt during cooling 

      Allabar, A.ORCIDiD; Dobson, K. J.; Bauer, C. C.; Nowak, M. (Contributions to Mineralogy and Petrology, 2020-02-12)
      The ascent of hydrous magma prior to volcanic eruptions is largely driven by the formation of H2O vesicles and their subsequent growth upon further decompression. Porosity controls buoyancy as well as vesicle coalescence ...
