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 ...

Fluid inclusion geochemistry examines microscopic droplets of palaeo-fluids trapped within minerals to reconstruct the physicochemical conditions of ancient hydrothermal systems. By analysing the ...

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 ...
