A molecular water pump in quartz dislocations

  author={M I Heggie},
RECENTLY Bakker and Janssen1 have reported experiments suggesting that water leaks out of bubbles in quartz preferentially along dislocations against thermodynamic gradients in fugacity, chemical potential and pressure. This effect indicates that the density of gas-rich fluid inclusions cannot be calculated from metamorphic pressure–temperature conditions and, conversely, that the density of the fluid cannot be used to infer metamorphic pressure–temperature conditions. Using computer modelling… CONTINUE READING
