摘要
The results of U–Pb Isotope Dilution Thermal Ionization Mass Spectrometry (ID-TIMS) geochronological studies of perovskite from kimberlite rocks of the Manchary pipe (Khompu-Maya kimberlite field, Central Yakutia) are reported. The obtained U–Pb age (472 ± 1 Ma) indicates the Early Paleozoic age of the formation of the Khompu-Maya field kimberlites and allows us to identify a new Aldan kimberlite subprovince within the Aldan anteclise.
