Liquid-filled rocks form when minerals trap fluids, but depending on their composition they can either be classed as enhydros, enhydro agates, or fluid inclusions. An enhydro is a hollow nodule that ...

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 ...

Using advanced techniques like nucleation-assisted microthermometry of initial one-phase fluid inclusion and triple-oxygen-isotope geochemistry, the team uncovered new insights into how these prized ...
