U–Pb zircon dating of felsic volcanic rocks from the Konachan Complex (Algan Mountains, northwestern Koryak Highland) confirmed their Late Miocene age (34.6 ± 0.5–38.8 ± 0.4 Ma, Priabonian). It is shown that these rocks are represented by moder

The isotopic dating of U-Pb by the zircon method of volcanic acid zircons of the Konachan complex (Algansky mountains, northwestern part of the Koryak highlands) confirmed their Late Eocene age (34.6 ± 0.5-38.8 ± 0.4 Ma, Priabon). It has been shown

Based on the obtained zircon dating two major domains are recognized: Triassic and Late Neoproterozoic, with Early Paleozoic (Cambrian–Ordovician) and Middle Neoproterozoic dates. The Early Mesozoic–Late Permian zircon dates megaclaster character

The Ust-Belaya ophiolite terrane in the West Koryak Orogen, which is the largest in northeastern Asia, consists of three nappe complexes. The upper Ust-Belaya Nappe is composed of a thick (>5 km) sheet of fertile peridotites and mafic rocks (remnants

The Tamvatnei ophiolite massif is located in the external part of the Koryak-Kamchatka accretionary orogen, within the limits of the Anadyr-Koryak Fold System (Late Cretaceous accretion), composed largely of complexes of enzymatic island arcs and bac

Isotope datings of amphibole-bearing mafics and metamafics in the northern part of the Anadyr-Koryak region allow clarification of the time of magmatic and metamorphic processes, which are synchronous with certain stages of the geodynamic development

In the Late Cretaceous starting from the early Coniacian, three parallel suprasubduction structural units have developed contemporaneously in the northwestern Paleopacific framework: (1) the Okhotsk-Chukchi arc at the Asian continental margin, (2) th

The northeastern segment of the Late Cretaceous suprasubduction Okhotsk-Chukotka volcanic belt is not an analogue of Andean-type continental margin. During its formation, the belt was separated from the Paleopacific by a complexly built assembly that
