“…On the other hand, it is not unusual to observe a very week efflux on volcanoes exhibiting intense plume activity from a central crater. In the case of White Island, New Zealand, plume CO 2 efflux was measured to be 2570-2650 ton/day, whereas diffuse CO 2 efflux was only 8.7 ton/day (WARDELL et al, 2001). Similar contrasts have also been reported for the Nisyros volcano, Greece (BROMBACH et al, 2001).…”

Absrtract-Since the 8th century, more than seventeen eruptions have been recorded for the Mt. Fuji volcano, with the most recent eruption occurring in 1707 (Hoei eruption). For the past 300 years the volcano has been in a quiescent stage and, since the early 1960s, has exhibited neither fumarolic nor thermal activity. However, the number of low-frequency earthquakes with a hypocentral depth of 10-20 km increased significantly beneath the northeastern flank of Mt. Fuji in 2000-2001, suggesting a possible resumption of magmatic activity. In this study, diffuse CO 2 efflux and thermal surveys were carried out in four areas of the volcano in 2001-2002 in order to detect possible signs of the upward movement of deep magma. At all survey points, the CO 2 efflux was below the detection limit with the exception of a few points with biological CO 2 emission, and ground temperatures at a depth of 20-30 cm were below ambient, indicating no surface manifestations of gas or heat emission. Should magma rise into the subsurface, the diffuse CO 2 efflux would be expected to increase, particularly along the tectonically weakened lineation on the Mt. Fuji volcano, allowing for the early detection of pre-eruptive degassing.

“…Compositions of MI from all three phenocryst minerals are identical within analytical error, confirming that all three were co-precipitating from the same melt (Rapien, 1998;Wardell et al, 2001). In terms of major element chemistry, the MIs resemble typical calc-alkaline dacites (Fig.…”

Partitioning behavior of Sc, Ti, V, Mn, Sr, Y, Zr, Nb, Ba, La, Nd, Sm, Eu, Gd, Dy, Ho, Yb, Hf, and Pb between dacitic silicate melt and clinopyroxene, orthopyroxene, and plagioclase has been determined based on laser ablation-inductively coupled plasma mass spectrometric (LA-ICPMS) analysis of melt inclusions and the immediately adjacent host mineral. Samples from the 1988 eruption of White Island, New Zealand were selected because petrographic evidence suggests that all three mineral phases are in equilibrium with each other and with the melt inclusions. All three phenocryst types are found as mineral inclusions within each of the other phases, and mineral inclusions often coexist with melt inclusions in growth-zone assemblages. Compositions of melt inclusions do not vary between the different host minerals, suggesting that boundary layer processes did not affect compositions of melt inclusions and that post-trapping modifications have not occurred.Partition coefficients were calculated from the host and melt inclusion compositions and results were compared to published values. All trace elements examined in this study except Sr are incompatible in plagioclase, and all measured trace elements except for Mn are incompatible in orthopyroxene. In clinopyroxene, Sc, V, and Mn are compatible, and Y, Ti, HREE, and the MREE are only slightly incompatible. Most partition coefficients overlap the wide range of values reported in the literature, but the White Island data are consistently at the lower end of the range in published values. Results from the literature obtained using modern microanalytical techniques such as secondary ion mass spectrometry (SIMS) or proton induced X-ray emission spectroscopy (PIXE) also fall at the lower end of the published values, whereas partition coefficients determined from bulk analysis of glass and crystals separated from volcanic rocks typically extend to higher values. Rapid crystal growth-rates, crystal zonation, or the presence of accessory mineral inclusions in phenocrysts likely accounts for the wide range and generally higher partition coefficients obtained using bulk sampling techniques. The results for 3+ cations from this study are consistent with theoretical predictions based on a lattice strain model for site occupancy. The results also confirm that the melt inclusion-mineral (MIM) technique is a reliable method for determining partition coefficients, as long as the melt inclusions have not experienced post-entrapment reequilibration.

“…Because volatiles have drastic effects on silicate melts, knowledge of their pre-eruptive concentrations is crucial to our understanding of magmatic phase equilibria (Holloway & Blank, 1994). An important application of dissolved water content of melts is that the depth at which a MI is trapped may be deciphered from such data (Roedder 1984;Sommer, 1979Roggensack, 2001;Wardell et al, 2001). In this way, volatile contents may be helpful for determining the pressures at which differentiation processes occur.…”
