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 Paleocenendash;Middle Eocene, as young as 45ndash;50 Ma), cross-cutting Shamanka pluton 45nbsp;Ma), and an overlap sequence of the Kinkil volcanics 45nbsp;Ma tightly bracket the timing of collision of the far-traveled Olutorsky terrane to the Middle Eocene. This collision may have driven change in plate movement that resulted in the establishment of the Aleutian Arc at this time, which trapped a fragment of the Kula plate now in the Bering Sea).
