Journal ArticleDOI
Study of the mechanism of the influence of water on elastic wave propagation in amphibolites and some metamorphic rocks at high pressures and temperatures
TL;DR: In this paper, an experimental study of the compressional and shear wave velocities of amphibolite, granite, pyroxenite, serpentinite and obsidian at water pressures up to 500 MPa and temperatures up to 800°C has been conducted.
Journal ArticleDOI
Study of intergranular films and interstitial phases in geomaterials using high temperature centrifuge and ultrasonic method at high pressure
E. B. Lebedev,A. V. Zharikov +1 more
TL;DR: The results obtained using the ultrasonic method at temperature up to 950 °C and under fluid pressure of 300 MPa revealed that the formation of intergranular melt films and interstitial phases network depend on chemical composition of fluids as discussed by the authors.
Journal ArticleDOI
The effects of water fluid at temperatures up to 850°C and pressure of 300 MPa on porosity and permeability of amphibolite
TL;DR: In this paper, the authors measured porosity, permeability and pore size distribution of amphibolite samples under gas and water fluid pressure of 300 MPa and at temperatures up to 850°C.
Journal ArticleDOI
Influence of fluids on the elastic properties of sandstone at high pressure and temperature
E. B. Lebedev,B. N. Ryzhenko,A.M. Dorfman,S. R. Zebrin,N. T. Sokolova,H. Burkhardt,R. Mörig,A. Wulff +7 more
TL;DR: In this paper, an experimental study of the influence of fluids on the elastic properties of sandstone as a model rock system for crustal conditions was performed at a hydrostatic pressure of 300 MPa and temperature up to 850°C.
Journal ArticleDOI
Effect of saturating fluid composition on the rock microstructure, porosity, permeability and Vp under high pressure and temperature
TL;DR: In this paper, the porosity and permeability changes due to the rock microstructure changes with Vp trends synchronously were associated with rock thermal decompaction and geochemical transformation caused by the effects of water fluids of different composition, metasomatic and hydration-dehydration reactions, silicification and phase transitions.
