EXPERIMENTAL CONSTRAINTS ON DEGASSING OF MAGMA: ISOTHERMAL BUBBLE GROWTH DURING CONTINUOUS DECOMPRESSION FROM HIGH PRESSURE

Gardner J.E.; Hilton M.; Carroll M.R. (1999)

Numerical models predict that rapid ascent of hydrous magma can lead to supersaturation of dissolved volatile constituents, possibly leading to explosive eruption. We have performed controlled decompression experiments to ...
MECHANICAL AND PHASE EQUILIBRIA IN INCLUSION-HOST SYSTEMS

Zhang Y. (1998)

Mechanical and phase equilibria in inclusion-host systems are investigated in this paper. An inclusion-host system that is initially under lithostatic pressure and in mechanical and phase equilibria may undergo ...
MIXING OF METAMORPHIC AND SURFICIAL FLUIDS DURING THE UPLIFT OF THE HERCYNIAN UPPER CRUST: CONSEQUENCES FOR GOLD DEPOSITION

Boiron M.C.; Cathelineau M.; Banks D.A.; Fourcade S.; Vallance J. (2003)

A detailed geochemical study of fluids from representative quartz-sealed faults hosting late Hercynian gold concentrations shows that fluids percolating the mineralised faults had two main distinct reservoirs: one was a ...
P-T PHASE RELATIONS OF SILICIC, ALKALINE, ALUMINOUS LIQUIDS: NEW RESULTS AND APPLICATIONS TO MANTLE MELTING AND METASOMATISM

Draper D.S.; Green T.H. (1999)

We report new experimental results obtained under nominally anhydrous conditions at 1.0-1.5 GPa on a synthetic melt whose composition is typical of extreme-composition xenolith glasses. These results demonstrate that part ...
PRESSURE SOLUTION IN SEDIMENTARY BASINS: EFFECT OF TEMPERATURE GRADIENT

Yang X.S. (2000)

Pressure solution is an important process in sedimentary basins, and its behaviour depends mainly on the sediment rheology and temperature distribution. The compaction relation of pressure solution is typically assumed to ...
THERMAL EFFECTS OF RIDGE SUBDUCTION AND ITS IMPLICATIONS FOR THE ORIGIN OF GRANITIC BATHOLITH AND PAIRED METAMORPHIC BELTS

Iwamori H. (2000)

Distribution of temperature and H2O in subduction zones during the course of ridge subduction are investigated numerically, in order to constrain the timing and extent of metamorphism and melting within the subducting ...
TRACE ELEMENT BEHAVIOR IN HYDROTHERMAL EXPERIMENTS: IMPLICATIONS FOR FLUID PROCESSES AT SHALLOW DEPTHS IN SUBDUCTION ZONES

You C.F.; Castillo P.R.; Gieskes J.M.; Spivack A.J. (1996)

Chemical evaluation of fluids affected during progressive water-sediment interactions provides critical information regarding the role of slab dehydration and/or crustal recycling in subduction zones. To place some constraints ...
