Fluids and/or liquids trapped in the minerals during their growth (primary inclusions) or in a later time as a result of opening and healing of fractures (pseudosecondary and secondary inclusions).
INFORMATIONS PROVIDED BY MICROTHERMOMETRIC DATA
From the microthermometric data it is possible to know:
The fluid composition and density are needed to obtain the trapping conditions (temperature and pressure) of the fluids by softwares that use the MRK equation of states.
The data obtained from fluid inclusion study are used in many investigation fields.
Examples of fluid inclusions
Salt inclusions and carbonatic melt inclusions
Silicate melt inclusions
