(2004)Measurements of the speed of sound in water have been extended to 5.5 GPa and 400°C. The data were taken in the diamond-anvil cell using Impulsive Stimulated Scattering (Forced Rayleigh Scattering) at acoustic frequencies ...
-
(2002)Physical properties including the equation of state, elasticity, and shear strength of pyrite have been measured by a series of X-ray diffraction in diamond-anvil cells at pressures up to 50 GPa. A Birch-Murnaghan equation ...
-
(2004)The behaviour of synthetic Mg-ferrite (MgFe2O4) has been investigated at high pressure (in situ high-pressure synchrotron radiation powder diffraction at ESRF) and at high temperature (in situ high-temperature X-ray powder ...
-
(2003)An equation of state (EOS) based on thermodynamic perturbation theory is presented for the NaCl-H2O-CH4 system. This equation consistently reproduces PvTX properties and phase equilibria with an accuracy close to that of ...
-
(2002)Calculations using equations of state to predict the phase behavior and composition of hydrocarbon species are finding use as an exploration technique. Equations of state give insight into the chemical changes induced in ...
-
(1988)In the present paper we emphasize that only the techniques of statistical mineralogy have been able to establish that the relatively high frequency of equiatomic minerals with end-member ratios between approximately 40:60 ...
-
(2001)It may be endemic to mechanistic modelling of complex environmental systems that there are many different model structures and many different parameter sets within a chosen model structure that may be behavioural or ...
-
(2002)The dissolution and transformation of soddyite ([UO2]2SiO4 · 2H2O) have been examined in aqueous suspension at pH 6 and 0.01 M NaNO3. Soddyite is an important component of the paragenetic sequence of secondary minerals ...
-
(1997)A suite of divalent metal (Ca, Cd, Ba) carbonates was synthetized over the temperature range 10-40°C by the classical method of slowly bubbling N2 through a bicarbonate solution. It was discovered that carbonates could be ...
-
(1988)We have determined the Fe-Mg fractionation between coexisting garnet and orthopyroxene at 20–45 kb, 975–1400 C, and the effect of iron on alumina solubility in orthopyroxene at 25 kb, 1200 C, and 20 kb, 975 C in the FMAS ...
-
(2000)Equilibrium volumes and expansivities of three liquids in the system anorthite (CaAl2Si2O8)-diopside (CaMgSi2O6) have been derived from dilatometric measurements of the equilibrium length of samples in the glass transition ...
-
(1997)A close relationship between the second-order Doppler shift (SOD) of the Mossbauer resonant recoil-free frequency and the equilibrium stable isotope fractionation has been established. The reduced isotopic partition function ...

-
(1995)The equilibrium oxygen isotope fractionation between grossular/andradite garnet and calcite has been determined experimentally by direct exchange from 800-1200°C at ~23 kbar. A least-squares fit to the equilibrium fractionation ...
-
(1996)The stable isotopic composition (C, O, H, and S) of a fluid in equilibrium with the common metapelite assemblage graphite + sulfide has been calculated using a modified Redlich-Kwong equation of state at 500°3.5 kbar, and ...
-
EQUILIBRIUM OXYGEN, HYDROGEN AND CARBON ISOTOPE FRACTIONATION FACTORS APPLICABLE TO GEOLOGIC SYSTEMS (2001)As demonstrated by the chapters in this short course, stable isotope techniques are an important tool in almost every branch of the earth sciences. Central to many of these applications is a quantitative understanding of ...
-
(1989)The value of analyzing the morphology of mineral crystals and of determining their equilibrium shapes as a point of reference for such an analysis is difficult to overestimate, since it offers the potential for real progress ...
-
(1990)The identification of equilibrium mineral assemblages in rocks is an important problem which can be solved not only by applying the principles of physical chemistry but also by observing the morphological characteristics ...
