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.
