The following U–Pb ages (Ma) were obtained for zircons from volcanic rocks and granitoids representing various complexes of the Nembonda Depression (the Anadyr segment of the Okhotsk–Chukotka Belt): 147.7 ± 2; 123.8 ± 1.7; 119.3 ± 1.7; 95.8 ± 0.5; and 80.55 ± 0.96. These results support the hypothesis of a significant Aptian igneous event in the Verkhoyansk–Chukotka region and provide the basis for the revision the boundaries of the Okhotsk–Chukotka Belt.
