DataAcquisition Depending on what the fluid inclusion look
Depending on what the fluid inclusion looks like it is possible to determine the approximate conditions in which it formed. If there is a halite crystal within the inclusion at room temperature, it is inferred that the fluid contains more than 26 wt% NaCl. If the vapor bubble is small, it can be assumed that the fluid originated from a liquid-like fluid because of its relatively high density. If the vapor bubble is very large, it can be inferred that the fluid was derived from a vapor-like fluid because of its relatively low density. The conditions of a minimum temperature of formation for a particular fluid inclusion (or assemblage) can be determined by heating the fluid inclusion to its homogenization temperature. The homogenization temperature is a temperature at which the bubble within the fluid inclusion disappears and all that remains is a single phase fluid. At that particular temperature there is an isochore (line of constant density) that can be projected from the liquid-vapor line on a temperature vs pressure phase diagram. If the pressure conditions are well constrained and appropriately estimated then the temperature of entrapment can be found where the isochore crosses the estimated pressure value.<br:/>To determine the salinity of the fluid, the fluid inclusion (or assemblage) must undergo freezing, usually below the eutectic temperature. As the temperature of the fluid inclusion drops and eventually freezes completely, the vapor bubble will deform and possibly move slightly. After freezing, the sample is gradually heated, the first melting occurs at the eutectic temperature which is representative of the fluid-salt composition. This can be determined by the vapor bubble “unlocking” from the frozen liquid and returning to its normal shape. Continued heating leads to the last bits of ice to melt, the temperature at which the last ice crystals melt can determine the weight percent of salt in the fluid using a salt vs temperature phase diagram.

Pitfalls Having an unqualified fluid inclusionist a
Having an unqualified fluid inclusionist analyze the sample and generate inaccurate data. It is very easy to misinterpret fluid inclusions and get data that is not representative of the true fluid composition or evolution. It is important to recognize that a fluid inclusion assemblage represents a single fluid’s physical and chemical properties at that particular point in time and space. While a fluid inclusion assemblage immediately adjacent could have very different chemical and physical characteristics representing a different fluid from a different point in the evolution of the hydrothermal system.
