Thallium (Tl) isotope ratios are an emerging tool that can be used to trace crustal recycling processes in arc lavas and ocean island basalts (OIBs). is a highly volatile metal enriched volcanic fumaroles, but it unknown whether degassing of Tl from subaerial has significant effect on their residual compositions. Here, we present concentration data experiments best explained by Rayleigh kinetic...

Purpose. To identify features of methane-air mixture flow within the steel degassing pipelines as well those ones made composite materials, to develop engineering solutions improving their reliability for actual use. Methodology. solve problem increasing capacity mine pipelines, an analysis fundamental studies on physical and mechanical properties methane processes its recovery in a environment...

The basic aspects of redox geochemistry are reviewed to provide a useful compendium the connection between aqueous-hydrothermal and igneous realms Earth. description system is intimately coupled knowledge acid-base properties solvent in which exchanges take place. For magmas, then silicate melts, approaches reporting state were so far cantered around sole concept oxygen fugacity, f O 2 . Master...
