Description:
Geosphere is constantly crossed by fluid fluxes of varying flow velocity and chemical composition.
The development of gas geochemistry techniques over the last 50 years allowed of gaining a
significant understanding of gas accumulations, gas fluxes, and their geological sources.
Although gas geochemistry is a relatively recent discipline of geochemistry, advancements over
the last 2 decades in sampling, storage and analysis of gas samples have enabled gas geochemistry to
emerge as a critical scientific tool for constraining processes occurring in the geosciences. Chemical
and isotopic features of various gas species have provided critical information about their origin,
source, migration, and accumulation in specific environments, making gas geochemistry a widely
used tool in a variety of fields of geosciences, including environmental/climate problems, geohazards,
origin and evolution of rocks, as well as biogeochemical processes involving microbial activity. Due
to the economic relevance of hydrocarbons and hydrothermal gases, they have been investigated
more intensively than other gas types since very early time. Additionally, advances in our
understanding of unconventional gases such as shale and tight gas in recent decades, represent
new applications for these gas-related approaches. Over the last half-century, scientists in the field of
gas geochemistry have exchanged their findings/experiments at major international scientific
conferences organized by the International Conference on Gas Geochemistry (ICGG), the
Geochemical Society, the American Geophysical Union (AGU), the European Geosciences
Union (EGU), the American Association of Petroleum Geologists (AAPG), and the
International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI).
Numerous applications of gas geochemistry in geology and the environment have been studied
in recent years, and the present trend confirms that Earth and Environmental Sciences are the most
promising domains for gas geochemistry applications. It is worth noting that advances in our
understanding of noble/rare gas geochemistry are more closely tied to technology achievements than
to fundamental geological knowledge. The current Research Topic has been devoted of compiling the
most recent and pertinent experiences in the various domains of gas geochemistry. 23 papers
presented but not limited in the 2019 ICGG meeting in Sicily have been accepted for publication.
