Fluid inclusions in minerals may form in any type of volcanic or plutonic rock ranging from mafic to silicic compositions. Because all igneous rocks reach fluid saturation at some stage during their evolution, fluids trapped as inclusions in magmatic minerals belong to a certain paragenesis or phase assemblage, which may include minerals, melts and one or more fluid phases. These fluid inclusions reflect one or more stages during rock evolution, and can be used to constrain multistage formation and evolution processes including ascent histories, magma chamber processes and crystallization behavior.

Fluid inclusions can provide thermobarometric data on various timescales. During...
