(2004)As magma rises from depth, it forms bubbles by nucleation, followed by diffusion-decompressive expansion. Expansion induces shearing, and shearing in turn causes coalescence. As the bubbles grow larger, coalescence gradually ...
-
(2004)A model of bubble growth during decompression of supersaturated melt was developed in order to explore the conditions for preservation of gas overpressure in bubbles or for maintaining supersaturation of the melt. The model ...
-
(1998)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 bubbles close to the initial pressure ...
-
(2000)High melt viscosity is thought to hinder bubble growth in water-bearing silicate melts, and viscosities above ~109 Pa s may prevent growth and viscously quench a bubbly liquid. To investigate the influence of melt viscosity ...
-
(2000)We report experimental data of bubble growth in natural rhyolitic melt with 1.4-2.0 wt% initial total H2O at 0.1 MPa and 500-600°C. Growth of many bubbles is monitored in every experiment. Bubble growth rate increases with ...
-
(1996)Bubble growth controlled by mass transfer of water from hydrated rhyolitic melts at high pressures and temperatures was studied experimentally and simulated numerically. Rhyolitic melts were hydrated at 150 MPa, 780-850 ...
-
(2006)Melts formed by small degrees of partial melting are rich in volatiles and may reach critical supersaturation during slow ascent or due to partial crystallization. Following nucleation, the bubbles grow and, if magma volume ...
-
(2001)CO2 is relatively insoluble in basaltic magma at low crustal pressures. It therefore exists as a gas phase in the form of bubbles in shallow crustal reservoirs. Over time these bubbles may separate gravitationally from the ...
-
(2005)It is the great challenge of geomicrobiology to study microorganisms in the context of their environments, both in Earth’s distant past and in the present. Planet Earth and its biosphere have evolved together, and a chronicle ...
-
(2003)Paired apatite fission track and U-Th/He dates provide the first Late Cenozoic cooling ages for the northern Tien Shan. These data clearly argue for pulsed deformation since the Late Miocene, with early (11–10 Ma) and late ...
