Abstract

Gas geochemistry and their associated isotope systematics are developing into powerful tools to understand geological/environmental processes and affirm source origins of geo-fluids. In addition to the traditional noble gas indicators, such as He and Ar, other major and trace gases, including CO2, N2, H2, CH4, CO, Ne, Kr and Xe – abundances and isotopes - have shown considerable application in many fields of the Earth and Environmental Sciences. For example, key constraints on geochemical processes including the degassing history of the solid Earth to form the atmosphere and oceans, the origin and migration characteristics of natural gas, the scale of climate variability, the P-T characteristics of both subaerial and deep water geothermal reservoirs, and the dynamics of the earthquake cycle, are only a few areas where gas geochemistry has been successfully exploited. Following the ‘Frontiers in Gas Geochemistry’ Special Issue in this journal (2013), this volume will reflect this diversity in scope and application of gas geochemistry, focusing on geothermal, tectonic and magmatic studies amenable to the gas geochemistry approach.
