PHREEQC is a geochemical computer code developed by the United States Geological
Survey and used to model mineral solubilities, aqueous solutions, and water-rock …

Deep fluids are important for the evolution and properties of the lower continental and arc
crust in tectonically active settings. They comprise four components: H2O, nonpolar gases …

The thermodynamic properties of 154 mineral end‐members, 13 silicate liquid end‐
members and 22 aqueous fluid species are presented in a revised and updated data set …

Consideration of interactions between neutral aqueous species and H 2 O dipoles in terms
of effective Born coefficients permits extension of the revised HKF (Helgeson, Kirkham and …

The solubility of quartz in H 2 O has been determined experimentally from 5 to 20 kb and
500 to 900° C. The results double the pressure range over which the molality of aqueous …

Extensive research during the 20 th century on porphyry Cu (-Mo-Au) deposits has revealed
the following major geodynamic, petrological, mineralogical, and geochemical features that …

This contribution provides an overview of available experimental, thermodynamic, and
molecular data on Au aqueous speciation, solubility, and partitioning in major types of …

Comprehensive quantitative theoretical evaluation of water–rock interactions in the Earth
has long been restricted to a pressure of 5.0 kb–too low to address processes involving …

A single-pass, flow-through apparatus was used to determine the dissolution rate of quartz
at 70° C as a function of pH and time. Dissolution rate data were obtained over the pH range …

The composition of REE minerals from the Bayan Obo Fe-REE-Nb deposit, China, varies
widely with paragenesis. The properties of fluid inclusions also vary with paragenesis …
