A NUMERICAL SIMULATION OF MAGMA MOTION, CRUSTAL DEFORMATION, AND SEISMIC RADIATION ASSOCIATED WITH VOLCANIC ERUPTIONS

Nishimura T.; Chouet B. (2003)

The finite difference method is used to calculate the magma dynamics, seismic radiation, and crustal deformation associated with a volcanic eruption. The model geometry consists of a cylindrical reservoir and narrow ...
DENSITY OF PERIDOTITE MELTS AT HIGH PRESSURE

Suzuki A.; Ohtani E. (2003)

Densities of ultramafic melts were determined up to 22 GPa by relative buoyancy experiments. Olivine and diamond were used as buoyancy markers. We confirmed that the density crossover of PHN 1611 melt and its equilibrium ...
ISOTOPIC DISEQUILIBRIUM DURING RAPID CRUSTAL ANATEXIS: IMPLICATIONS FOR PETROGENETIC STUDIES OF MAGMATIC PROCESSES

Davies G.R.; Tommasini S. (2000)

The geochemical consequences of crustal anatexis are investigated over a range of mineral dissolution rates; 10-10 cm/s (Mono Lake, CA), ~10-16 cm/s (Seram, Indonesia) and <10-16 cm/s (regional migmatite terranes). Isotopic ...
VISCOSITY OF ALBITE MELT AT HIGH PRESSURE AND HIGH TEMPERATURE

Suzuki A.; Ohtani E.; Funakoshi K.; Terasaki H.; Kubo T. (2002)

The viscosity of albite (NaAlSi3O8) melt was measured at high pressure by the in situ falling-sphere method using a high-resolution X-ray CCD camera and a large-volume multianvil apparatus installed at SPring-8. This system ...
