Despite nearly fifty years of modern research on silicate melt inclusions (MI), only within the past 10 similar to 15 years have volcanologists, petrologists and fluid inclusionists come to regularly accept their utility for characterizing magmatic systems. Their relatively slow acceptance was likely due to a number of factors including:1) Lack of reliable analytical techniques; 2) Concern that MI's evolution after trapping; 3) Data sets indicative of some heterogeneous melts existed; 4) High homogenization temperatures make the data not easy to reliable. With improvements in analytical methods and careful studies of MI systematics, workers are increasingly convinced of the utility of these features to unravel the complexities of magmatic systems. Melt inclusions have "come of age" Recent studies provide compelling evidence for the compositions of dissolved and exsolved volatiles in magma reservoirs. Evidence for immiscibility of gases, hydrosaline brines and magma demonstrate that magmatic phase relations are often more complicated than can be inferred by inspection of crystalline phase. After trapping melt inclusions may undergo significant change (crystallizations), and other potential phenomenon include diffusions of volatile, vapor exsolution, and venting. With careful study we can decide MI's composition is useful and reliable.
