The plate tectonic history of the Pacific Ocean and its predecessor ocean, Panthalassa, are the most challenging regions on Earth to reconstruct within the Mesozoic and Cenozoic eras (Müller et al., 2016). The Pacific Ocean currently covers >25% of the present Earth surface and is the largest ocean basin on Earth; however, the Pacific-Panthalassa oceanic realm was even larger during the late Mesozoic, when it covered ∼45% of Earth and 65% of oceanic areas (Torsvik et al., 2019). Much of the Pacific-Panthalassan realm has been recycled due to subduction, and the lost Pacific-Panthalassa oceanic lithosphere is one of the most significant contributors to uncertainties in global plate tectonics (Torsvik et al., 2019) and atmospheric CO 2 estimates (Müller et al., 2022;Van Der Meer et al., 2014) since the Triassic. This paper discusses the plate tectonic history of NW Pacific-Panthalassa and its implications for subduction histories and accreted oceanic terranes along East Asia (Figure 1a). We consider explicitly the remnants of Pacific-Panthalassa that were subducted and are now within Earth's mantle by presenting forward geodynamic models that assimilate contrasted NW Pacific-Panthalassa plate reconstructions and testing them against mantle structure, the geoid and dynamic topography. We discuss our model implications for NW Pacific-Panthalassan subduction histories and slab sinking histories under the central Pacific.

“…The Pacific and the Philippine Sea Plates are subducting under volcanic island arcs (i.e., SW Japan, NE Japan, Kuril, and Aleutian Island arcs) that developed around the margins of these continental plates (Figure 1a). However, many studies suggest that the oceanic plate configuration during the Late Cretaceous was noticeably different from that of today (e.g., Bazhenov & Burtman, 1994; Bazhenov et al., 2001; Domeier et al., 2017; Isozaki et al., 2010; Kimura, 1994; Maruyama et al., 1997; Müller et al., 2016; Seton et al., 2015; Taira, 2001; Vaes et al., 2019; Wu et al., 2022). During the Cretaceous, the Philippine Sea Plate did not yet exist.…”

“…During the Cretaceous, the Philippine Sea Plate did not yet exist. It is inferred that the Izanagi Plate, not the Pacific Plate, was subducting under the Eurasian Plate and Okhotsk Block (Domeier et al., 2017; Engebreston et al., 1985; Isozaki et al., 2010; Maruyama et al., 1997; Müller et al., 2016; Seton et al., 2015; Wu et al., 2022).

The Origin of the Paleo‐Kuril Arc, NE Japan: Sediment Provenance Change and Its Implications for Plate Configuration in the NW Pacific Region Since the Late Cretaceous

The Nemuro Belt is a tectonic belt in the Paleo‐Kuril Arc system, the NW Pacific region. The Paleo‐Kuril Arc has been interpreted as an intraoceanic arc system between the Izanagi and Pacific Plates during the Late Cretaceous, suggesting that the boundary between these plates was a trench. However, this study shows it was a volcanic arc that developed atop a continental margin. To determine the nature of this arc during the Late Cretaceous, U‐Pb ages of detrital zircons from the Nemuro and Urahoro Groups in the Paleo‐Kuril Arc were analyzed. Our results identify two distinct types of detrital zircon U‐Pb age distributions. The first (Type 1) is characterized by multimodal age distributions with peaks ranging from ca. 1.8 Ga to 78 Ma. The other (Type 2) exhibits a unimodal age distribution with a peak at 60‐52 Ma. These different age distributions indicate a provenance transition occurred between the Late Cretaceous and Paleogene. Precambrian zircons in Type 1 sandstones indicate that the Paleo‐Kuril Arc was part of a continental plate, presumably the Okhotsk Block, in NE Asia during the Late Cretaceous. In contrast, Type 2 sandstones were supplied only from the magmatic arc region that the Izanagi‐Pacific Ridge subduction could have activated. This provenance transition suggests the initially continental arc became separated from its continental source at the beginning of the Paleogene.

“…Finally, we place North America and the reconstructed forearc in a paleomagnetic reference frame and use the reconstructed paleo-ridge orientation to model a ridge-transform system that obeys the age distribution of the ophiolites. If such a reconstruction is possible and leads to a reasonable full-spreading rate [i.e., typically not more than ~10 cm/a, with exceptions up to 20 cm/a (Rioux et al, 2013;Wu et al, 2022;Zahirovic et al, 2015)], then the interpretation that the ophiolites represent relics of a coherent upper plate is permissible. Finally, we discuss implications of our study for the causes of ophiolite dismemberment and opportunities to learn about intra-plate geochemical and temporal variation.…”

Ophiolites, fragments of oceanic lithosphere exposed on land, are typically found as isolated klippen in intensely deformed fold-thrust belts spanning hundreds to thousands of kilometers along-strike. Ophiolites whose geochemistry indicates that they formed above subduction zones, may have been relics of larger, once-coherent, oceanic lithosphere tracts that formed the leading edge of an upper plate below which subduction occurred; such tracts were subsequently dismembered by deformation and erosion during orogenesis and uplift. However, to what extent the first-order original coherence is maintained between ophiolitic klippen is difficult to assess. Here, we aim to evaluate whether the Jurassic forearc ophiolites overlying subduction complex rocks in California, now scattered over 1000 km and dismembered by the wider San Andreas Fault Zone, still maintain their original lithospheric coherence. To this end we (i) compile available crustal ages from all ophiolite klippen exposed in the Jurassic ophiolite belt of the western United States; (ii) review and kinematically reconstruct post-middle Jurassic deformation that occurred between the modern western coast and the stable North American craton to restore the original positions of the ophiolite fragments relative to each other and to North America, and (iii) perform a paleomagnetic analysis of a sheeted dyke sections of the Mt. Diablo and Josephine ophiolites to estimate the orientation of the spreading axis at which the Jurassic Californian forearc ophiolites formed. The latter analysis reveals that the original ridge orientation likely trended ~080-260°, near-perpendicular to the orientation of the trench along the western margin of the ophiolite belt. We show that with these constraints, a straightforward ridge-transform system can explain the age distributions of the ophiolites with spreading rates of 7-10 cm/a. Our analysis shows that the Jurassic ophiolites of California may be considered klippen of a single sheet of oceanic lithosphere that accreted at a forearc spreading ridge. In addition, we show that kinematic and paleomagnetic analysis of ophiolite belts may provide novel constraints on the kinematic evolution of accretionary orogens and the plates now lost to subduction.
