U-Pb isotope is one of the isotopic dating and geochemical tracing techniques developed rapidly in reccent years. The isotope U-Pb zircon dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the 1950s of the 20th century. In addition, it can also use other minerals such as monazite, titanite, and baddeleyite to determine the age. The isotope ratios U- Pb in zircon minerals can be analyzed in many different ways and the results are accurate. One of the analysis methods that does not take much time for sample preparation process and results in high precision isotope analyzes is U-Pb zircon minerals of LA-ICP-MS.
