Abstract

Based on U-Pb dating (SHRIMP-II) of euhedral zircon cores from hypersthene-plagioclase granulites of the Kukhtui Inlier (Okhotsk Massif), their igneous protholith of the basic composition is estimated to be Archean in age (3.7 Ga), which is confirmed by the Sm-Nd measurements. Subsequent tectonothermal events are established to occur 3.3–3.2, 2.8–2.7, and 1.9–1.8 Ga ago.
