It also plays a key role in the evolutionof the Earth. Accurate thermodynamics data on water are currently confined to pressures below1.0 GPa and temperatures below 900℃. Presented in this paper are new data available on theP-T properties of water at pressures up t0 5. 0 GPa, developed from differential thermal analysis and ultrasonic wave amplitude analysis. It has been found that there may exist anotherternary point at 3. 0 GPa and that ultrasonic wave amplitude change of ice-water transitionshows two inflection points above 2. 0 GPa, consistent with the two peaks of differential thermal curves above 2. 0 GPa. It may be a new phenomenon which needs further study.展开更多

The results show that with increasing pressure the dehydrationtemperature of antigorite increases slightly below 2. 0 GPa, but drops markedly above 2. 0GPa. This strongly suggests that high pressure would favor the dehydration of serpentine minerals and the water released thereby would be an important source of fluids involved in magmatism in a subduction zone and mantle metasomatism. Meanwhile, the greatly enhanced electricconductivity in the presence of water may be one of the reasons underlying the occurrence of ahigh-conductivity zone in the lower crust.展开更多
