Abstract:

Petrographic microscopy of a rock and mineral sample is the first and at same time essential step of any fluid inclusion study. Fluid inclusion is a paleogeofluid trapped in minerals. To distinguish the primary and secondary fluid inclusions is an essential step, then a proper interpretation of fluid inclusions can be made only when textural relationship between fluid inclusion and the host mineral and rock are considered. This is the major subject for fluid inclusion petrography. A few methods to describe the essential part of fluid inclusion petrography are included.

Key words: fluid inclusion, petrography, primary and secondary fluid inclusion, host mineral.
