The size distribution of pyroclasts and the fragmentation sequence in explosive volcanic eruptions
E Kaminski, C Jaupart - Journal of Geophysical Research: Solid …, 1998 - Wiley Online Library
In an explosive eruption, the atmospheric column dynamics depend strongly on the mass
fraction of gas in the erupting mixture, which is fixed by fragmentation in the volcanic conduit …

Bubble growth in highly viscous melts: theory, experiments, and autoexplosivity of dome lavas
O Navon, A Chekhmir, V Lyakhovsky - Earth and Planetary Science Letters, 1998 - Elsevier
We examine the physics of growth of water bubbles in highly viscous melts. During the initial
stages, diffusive mass transfer of water into the bubble keeps the internal pressure in the …

Constraints on cooling rates and permeabilities of pumice in an explosive eruption jet from colour and magnetic mineralogy
In explosive volcanic eruptions, vesicular magma droplets, produced by fragmentation, are
propelled into the atmosphere where they are chilled to form pumices. The thermal history of …
