Isotope analysis of fluid inclusions entails the measurement of stable isotopes, chiefly oxygen (δ18O) and hydrogen (δ2H), in microscopic pockets of water or gas trapped within mineral matrices such ...

Most of the CO 2 released worldwide by arc volcanoes is recycled from subducted carbon 1,2. Carbon is carried to depth in carbonate minerals and organic material in altered oceanic crust and marine ...

Researchers report that rocks from Earth's upper mantle and lower oceanic crust in diverse geological settings around the world contain abiotic methane and hydrogen in fluid inclusions, likely formed ...

Gas-rich fluid inclusions containing CO2 (carbon dioxide) and CH4 (methane) were trapped in host minerals (here quartz) during crystal growth. Disclaimer: AAAS and EurekAlert! are not responsible for ...
