“…The Tonin‐Aniva terrane, composed of Aptian‐Cenomanian turbidites and olistostromes with lenses of Middle Triassic to Lower Cretaceous oceanic tholeiites and (sub)alkaline basalts, forms a subduction‐related trench‐fill terrane similar to the Hidaka belt (Nokleberg et al, ; Parfenov et al, ; Zharov, ). To the north, the East Sakhalin terrane forms a middle Cretaceous to Paleocene accretionary complex, hosting Upper Cretaceous‐Paleocene metamorphic rocks and an ophiolitic mélange with tectonic slices of Permian‐Late Cretaceous rocks (Khanchuk, ; Liao et al, ; Zhao et al, ; Zharov, ; Zyabrev, ; Figure ).…”

“…On the Tonin-Aniva peninsula, the timing of obduction is marked by Early Eocene sediments and tuffs in the Ozersk terrane, the occurrence of mid-Eocene (44-38) Ma granitoid intrusions that cut the suture zone (Glorie et al, 2017;Liao et al, 2018;Zharov, 2005) and an unconformable cover of Upper Eocene-Lower Oligocene terrigenous sediments (Zharov, 2005; and references therein). These observations constrain the obduction in southern Sakhalin to the Middle Eocene (Bazhenov et al, 2001;Parfenov et al, 2011;Zharov, 2005).…”

Reconstruction of Subduction and Back‐Arc Spreading in the NW Pacific and Aleutian Basin: Clues to Causes of Cretaceous and Eocene Plate Reorganizations

2019

The Eocene (~50–45 Ma) major absolute plate motion change of the Pacific plate forming the Hawaii‐Emperor bend is thought to result from inception of Pacific plate subduction along one of its modern western trenches. Subduction is suggested to have started either spontaneously, or result from subduction of the Izanagi‐Pacific mid‐ocean ridge, or from subduction polarity reversal after collision of the Olyutorsky arc that was built on the Pacific plate with NE Asia. Here we provide a detailed plate‐kinematic reconstruction of back‐arc basins and accreted terranes in the northwest Pacific region, from Japan to the Bering Sea, since the Late Cretaceous. We present a new tectonic reconstruction of the intraoceanic Olyutorsky and Kronotsky arcs, which formed above two adjacent, oppositely dipping subduction zones at ~85 Ma within the north Pacific region, during another Pacific‐wide plate reorganization. We use our reconstruction to explain the formation of the submarine Shirshov and Bowers Ridges and show that if marine magnetic anomalies reported from the Aleutian Basin represent magnetic polarity reversals, its crust most likely formed in an ~85‐ to 60‐Ma back‐arc basin behind the Olyutorsky arc. The Olyutorsky arc was then separated from the Pacific plate by a spreading ridge, so that the ~55‐ to 50‐Ma subduction polarity reversal that followed upon Olyutorsky‐NE Asia collision initiated subduction of a plate that was not the Pacific. Hence, this polarity reversal may not be a straightforward driver of the Eocene Pacific plate motion change, whose causes remain enigmatic.

U–Pb ages of zircons from metamorphic rocks in the upper sequence of the Hidaka Metamorphic Belt, Hokkaido, Japan: Identification of two metamorphic events and implications for regional tectonics

et al. 2021

The Hidaka Metamorphic Belt is a well-known example of island-arc crustal section, in which metamorphic grade increases westwards from unmetamorphosed sediment up to granulite facies. It is divided into lower (granulite to amphibolite facies) and upper (amphibolite to greenschist facies) metamorphic sequences. The metamorphic age of the belt was considered to be 55 Ma, based on Rb-Sr whole-rock isochron ages for granulites and related S-type tonalities. However, zircons from the granulites in the lower sequence yield U-Pb ages of 21-19 Ma, and a preliminary report on zircons from pelitic gneiss in the upper sequence gives a U-Pb age of 40 Ma. In this paper we provide new zircon U-Pb ages from two pelitic gneisses in the upper sequence to assess the metamorphic age and also the maximum depositional age of the sedimentary protolith. The weighted mean 206 Pb/ 238 U ages from a biotite gneiss in the central area of the belt yield 39.6 ± 0.9 Ma for newly grown metamorphic rims and 53.1 ± 0.9 Ma for the youngest detrital cores. The ages of zircons from a cordierite-biotite gneiss in the southern area are 35.9 ± 0.7 Ma for metamorphic rims and 46.5 ± 2.8 Ma for the youngest detrital cores. These results indicate that metamorphism of the upper sequence took place at 40-36 Ma, and that the sedimentary protolith was deposited after 53-47 Ma. These metamorphic ages are consistent with the reported ages of 37-36 Ma plutonic rocks in the upper sequence, but contrast with the 21-19 Ma ages of metamorphic and plutonic rocks in the lower sequence. Therefore, we conclude that the upper and lower metamorphic sequences developed independently but coupled with each other before 19 Ma as a result of dextral reverse tectonic movement.
