Geologic molecular hydrogen (H 2) occurs in the subsurface and vents and seeps at the
surface. However, this valuable natural resource is under-utilized in the economy because …

Natural gas has a critical place in global fuel energy mix, not least as a transition to low
carbon emissions. It plays an important role in national energy production and consumption …

Large-scale helium accumulations are rarely reported in tectonically active continental
subduction zones. This study shows geochemical variations in helium and other volatiles (N …

Exploring and exploiting high-temperature (even supercritical) geothermal resources are
significant to meet energy demands and reduce carbon emissions. The Yangbajing …

Mantle volatiles are transported to Earth's crust and surface by basaltic volcanism. During
subaerial eruptions, vast amounts of carbon, sulfur and halogens can be released to the …

Helium is extensively utilized in aerospace, healthcare, electronics, semiconductors,
advanced science, and renewable energy sectors, playing a pivotal role in the advancement …

The study on whether there is a magma chamber under Wudalianchi is a hot topic recently,
as it holds great significances for the theory of plate tectonics, early warning of volcano …

Determining the composition of the Archean atmosphere and oceans is vital to
understanding the environmental conditions that existed on the surface of the early Earth …

The origin of methane in hydrothermal fluids has long been a subject of debate–whether it is
abiotic or biotic. In this study, we aim to unravel and quantify the sources of CH 4 in active …

Springs discharge groundwater that travels along flow paths of different spatial and time
domains. In many instances, it is difficult to describe its involved groundwater movement …
