How and where did life on Earth originate? To date, various environments have been
proposed as plausible sites for the origin of life. However, discussions have focused on a …

For many years, our understanding of the behavior of the REE in hydrothermal systems was
based on semi-empirical estimates involving extrapolation of thermodynamic data obtained …

Soil microorganisms globally are thought to be sustained primarily by organic carbon
sources. Certain bacteria also consume inorganic energy sources such as trace gases, but …

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 …

The development of highly accurate and computationally efficient modeling software based
on Gibbs energy minimization (GEM) makes it possible to thermodynamically simulate …

Abiotic hydrocarbons and carboxylic acids are known to be formed on Earth, notably during
the hydrothermal alteration of mantle rocks. Although the abiotic formation of amino acids …

Recent advances in theoretical geochemistry permit calculation of the standard molal
thermodynamic properties of a wide variety of minerals, gases, aqueous species, and …

Abstract The Eu 3+ Eu 2+ redox boundary for temperatures up to 600° C and pressures up
to 4000 bar has been calculated using the “revised HKF model” for the prediction of the …

The oxidative degradation of organic matter is a key process in the biogeochemical
functioning of the earth system. Quantitative models of organic matter degradation are …

The development of Thermoddem, a thermodynamic database devoted to geochemical
modelling for environmental studies in general and, more specifically, to chemical systems …
