New data from geothermal wells in Iceland have permitted empirical calibration of the
chalcedony and Na K geothermometers in the range of 25–180° C and 25–250° C …

The solubility of uranyl minerals controls the transport and distribution of uranium in many
oxidizing environments. Uranyl minerals form as secondary phases within uranium deposits …

Alkali–silica reaction (ASR) is a major concrete durability problem, resulting in significant
maintenance and reconstruction costs to concrete infrastructures all over the world. Despite …

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 …

Critically selected values for the entropy (S 298.15), molar volume (V 288.15), and for the
heat and Gibbs free energy of formation (AH, f, 298.15 and AG, 298.15) are given for 50 …

Many mesothermal gold-quartz deposits are localized along high-angle reverse or reverse-
oblique shear zones within greenstone belt terrains. Characteristically, these fault-hosted …

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 …

Using chemical analyses and 25° pH measurements of quenched high-temperature waters,
we calculate in situ pH and distribution of aqueous species at high temperature. This is …

The source of the ore fluid and hence of the gold in orogenic lode gold deposits remains
unresolved. The consensus that the ore fluid of orogenic deposits of all ages and settings is …

The formation of ore deposits and the patterns of mineral alteration in rocks frequently
involves the transport of large amounts of dissolved solids, sometimes transiently, but often …
