Fluid inclusions are microscopic cavities within minerals where fluid has become trapped.
Whenever a crystal grows or recrystallizes in fluid, such as that taking place on the ocean floor, irregularities in mineral growth result in small portions of fluid being trapped. The fluid can become trapped during crystal growth or seep through fractures and become trapped as the mineral heals, resulting in any given sample containing many generations of inclusions. An inclusion that occurs during mineral growth is called a primary inclusion. They are usually large and solitary. Healing of fractures during crystal growth produces pseudosecondary inclusions and healing of fractures at some later time produces secondary fluid inclusions, which tend to be small, located along planes of fracture and more numerous.
