Fluid inclusions entrapped in mineral cements and healed microfractures represent an important source of information on the ambient environment during mineral precipitation. This includes minerals precipitated in relatively low-temperature, surficial environments, which have been identified as targets for exploration for life on the Martian surface. As inclusion fluids are sealed from alteration, they preserve a record of the environment at a time when water was present. The most direct value of inclusions would be in biomolecular signatures in aqueous fluids, or physical remains of micro-organisms held in the fluids. High-resolution sensing techniques for organic molecules could analyse inclusion fluids released in situ on Mars or from returned samples.
