The collision of the Cretaceous Olutorsky Island Arc with eastern Eurasia margin in the northwest Pacific is a critical event in Cenozoic evolution of the Pacific Rim. The timing of synorogenic flysch deposition (Paleocene–Middle Eocene, as young a

Two belts of subaerial volcanic rocks—the Eocene Kinkil belt and the Neogene belt of the Sredinny Range—extend along the Kamchatka Isthmus. It is suggested that their formation is related to subduction of the oceanic lithosphere beneath the conti

The lateral variability of structural elements in the collision zone of the Cretaceous-Paleocene Achaivayam-Valagin island arc with the northeastern Asian margin is considered. The similarity and difference of Eocene collision structural elements in

In the Sredinnyi Range of Kamchatka, the Baraba Formation of continental conglomerates is assumed to be of the late Campanian age based on found flora remains, but data of isotopic geochronology suggest the Eocene age of these deposits. New data on r

Ophiolites of the Afrika Mys Block of the Kamchatsky Mys Peninsula, eastern Kamchatka, are a fragment of an accretionary prism that formed in the Late Cretaceous-Eocene on the southern side of the Kronotsky island arc as a result of its collision wit

The provenance and tectonic setting of the sediments and rare cobbles from the accretionary wedge on Karaginski Island were examined. This study provides a picture of the nature of the NE Asian paleomargin in the middle Eocene to early Miocene. The t

The Lesnaya Group is part of a thick, poorly dated turbidite assemblage that sits in the footwall of a regionally extensive collision zone in which the Cretaceous–Paleocene Olutorsky island arc terrane was obducted onto continental margin basin str

The mineral composition of sandstones from Cretaceous-Lower Paleocene terrigenous sequences of the western Kamchatka-Ukelayat zone (southern Koryak Upland, western Kamchatka) suggests that the Okhotsk-Chukot volcanogenic belt and fragments of the Uda

The remnants of ancient island arcs are exposed in the Achayvayam-Valagina and East Peninsulas tectonic zones of the Olutor-Kamchatka region, northeast Russia. Geochemically, Late Cretaceous to Paleogene island arc complexes of the East Peninsulas zo
Late Cretaceous paleomagnetic data from the Median Range of Kamchatka, Russia: tectonic implications

A Late Cretaceous island arc complex was sampled for paleomagnetic study in the northern part of the Median Range of Kamchatka. In most samples, thermal demagnetization in 12–18 steps revealed either a reversed characteristic remanent magnetization
