Fluid inclusion
Definition
A microscopic cavity in a crystal trapped at the time of growth, containing the mineralising fluid or melt; analysed by microthermometry (freezing and heating to measure salinity and composition) and Raman spectroscopy (identifying dissolved species); a fingerprint of the geological formation environment.
