Two of the most common uses of melt inclusions are to study the compositions of magmas present early in the history of specific magma systems. Absolute dating uses clues, such as the emperor's face on a coin, to date an artifact. Unsourced material may be challenged and. Unlike relative age, which determines whether a formation is older or younger than its surrounding formations, absolute age provides geologists with the absolute dating science definition age of a formation. For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.
