Short-chain aliphatic acid anions, which are produced during the thermal maturation of
sedimentary organic matter, are common in oil-field brines and other deep formation fluids …

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 …

We propose here a new geothermometer for natural waters. Analyses from many explored
geothermal fields allow us to define two empirical thermometric relationships. One is for …

Subsurface saline waters in sedimentary basins can be divided into three groups based on
their anionic composition and salinity:(1) Waters with anions other than Cl dominant. These …

Geochemical modeling is a powerful tool for characterizing environmental site
contaminations and predicting environmental impacts. This book discusses the application …

Steady-state dissolution rates of albite were measured in aqueous solutions at 80° C and pH
8.8 as a function of solution saturation state (or the Gibbs free energy of reaction, ΔG r) using …

Thermodynamic calculations are an essential tool for many areas of geochemistry.
Thermodynamics provides a framework for the quantitative description and prediction of the …

Secondary porosity in sandstones is created by subsurface dissolution of grains or cement
by pore water that is undersaturated with respect to one or more of the major mineral …

Secondary porosity created by the post-depositional leaching of detrital grains and cements
can be of great economic importance. The term secondary porosity is only descriptive and …

The range of physical and chemical conditions included in diagenesis is 02000 C 1 2000 kg
cm2 and water salinities from fresh to brines twice as concentrated as the Dead Sea …
