In recent years, advances in analytical technology have made it possible to measure the U-Th-Pb dating of young geological units (e.g. 1 Ma). However, there are very few young standard samples available for evaluation. In this study, we attempted U-Pb dating using isotope dilution Thermal Ionization Mass Spectrometry (ID-TIMS) on young zircon samples (TRG04 and OGPK). As a result, we obtained preliminary U-Pb ages of 2.6654 0.0016 Ma and 1.1266 0.0014 Ma, respectively.
