Izanagi Plate
Subduction of the Izanagi-Pacific Ridge–transform intersection at the northeastern end of the Eurasian plate
The production of parallel world-class W and Cu metallogenic belts linked to an asymmetric slab window
A model is presented for the displacement history between western North America, eastern Eurasia, and adjacent oceanic plates (Pacific, Farallon, Izanagi, Kula, and Phoenix) for the past 180 million years. The model is based on the assumption that the hotspots in the Atlantic region have remained fixed relative to the hotspots in the Pacific basin (but not necessarily relative to the spin axis). The model uses a new determination for relative motion between the oceanic plates of the Pacific basin. The results show that in a broad sense the Kula and Izanagi plates moved in a general south to north direction through the Pacific basin, implying rapid subduction beneath Eurasia and right lateral oblique subduction with respect to North America. In contrast, the Farallon plate swept in a general west to east trajectory across the basin and was accompanied by rapid subduction beneath North America. The Kula and Izanagi plates were capable of transporting allochthonous terranes rapidly northward toward the paleopole. The Farallon plate was capable of transporting terranes bearing Tethyan fauna eastward across the Pacific basin and juxtaposing those terranes against the western edge of North America, with moderate displacements toward the paleopole. A set of maps showing reconstructed plate boundaries for the past 140 Ma provides the basis for interpreting terrane displacement histories. The reconstructions are also used to estimate the ages of the plates that were consumed at convergent plate boundaries throughout the late Mesozoic and Cenozoic eras. The following events and relationships are noted: (1) fast (greater than 100 km/m.y.) convergence of the Farallon plate with respect to North America during Late Cretaceous and early Tertiary times (75 to 40 Ma); (2) rapid trenchward migration of western North America over the hotspots during this same time interval; (3) rapid decrease in age of the subducting Farallon plate within this interval of fast convergence; (4) synchroneity of these three processes with the Laramide deformation; (5) decrease in Farallon–North America and North America–hotspot velocities at about 40 Ma as the age of the subducting Farallon lithosphere decreased rapidly to less than 30 m.y. Our analysis shows that the age and bathymetry of the descending plates varied markedly along strike of the trenches. Fracture zones on the Farallon plate, across which large age offsets occur, were characterized by shallow (young) and deep (old) ocean floor on opposite sides of the fracture zones. As the fracture zones migrated north with the Farallon plate along the continental margin, buoyant young lithosphere capable of producing uplift and erosion existed immediately adjacent to dense old lithosphere capable of forming a bathymetric low. We speculate that some of the basins that formed along the continental margin during late Cretaceous and Tertiary times may have originated in these source-sink pairs. The relative velocities between continents and adjacent oceanic plates are shown on a series of maps as arrows representing velocity vectors at selected points of tectonic interest around the Pacific margin. Significant changes through time in these relative plate velocities offer insights into the mechanisms that control the diversity of tectonic styles found in the geologic record at the margins.

A plate model for Jurassic to Recent intraplate volcanism in the Pacific Ocean basin
Reconstruction of the tectonic evolution of the Pacific basin indicates a direct relationship between intraplate volcanism and plate reorganizations, which suggests that volcanism was controlled by fracturing and extension of the lithosphere. Middle Jurassic to Early Cretaceous intraplate volcanism included oceanic plateau formation at triple junctions (Shatsky Rise, the western Mid-Pacific Mountains) and a diffuse pattern of ocean island volcanism (Marcus Wake, Magellan seamounts) reflecting an absence of any well-defined stress field within the Pacific plate. The stress field changed in the Early Cretaceous when accretion of the Insular terrane to the North American Cordillera and the Median Tectonic arc to New Zealand stalled migration of the Pacific-Farallon and Pacific-Phoenix ocean ridges, leading to the generation of the Ontong Java, Manahiki, Hikurangi, and Hess Rise oceanic plateaus. Plate reorganizations in the Late Cretaceous resulted from the breakup of the Phoenix and Izanagi plates through collision of the Pacific-Phoenix ocean ridge with the southwest margin of the basin and development of island arc–marginal basin systems in the northwestern part of the basin. The Pacific plate nonetheless remained largely bounded by spreading centers, and intraplate volcanism followed preexisting lines of weakness in the plate fabric (Line Islands) or resulted from fractures generated by ocean ridge subduction beneath island arc systems (Emperor chain). The Pacific plate began to subduct under Asia in the Early Eocene as inferred from the record of accreted material along the Japanese margin. Further changes to the stress field at this time resulted from abandonment of the Kula-Pacific and the North New Guinea (Phoenix)–Pacific ridges and from development of the Kamchatkan and Izu-Bonin-Mariana arcs, leading to the generation of the Hawaiian chain as a propagating fracture. The final major change in the stress field occurred in the Late Oligocene as a result of breakup of the Farallon into the Cocos and Nazca plates, which caused a hiatus in Hawaiian volcanism; initiated the Sala y Gomez, Foundation, and Samoan chains; and terminated the Louisville chain. The correlations with tectonic events are compatible with shallow-source models for the origin of intraplate volcanism and suggest that the three principal categories of volcanism, intraplate, arc, and ocean ridge, all arise from plate tectonic processes, unlike in plume models, where intraplate volcanism is superimposed on plate tectonics.

CRETACEOUS RIDGE SUBDUCTION ALONG THE LOWER YANGTZE RIVER BELT, EASTERN CHINA
We present a comprehensive study of one of the key targets of the Sikhote-Alin orogen—Early Cretaceous rocks in the Kiselevka block of the Kiselevka-Manoma tectono-stratigraphic terrane. The characteristic component of natural remanent magnetization (NRM) for these rocks was isolated, and the fold test was positive (Dec = 275.8°, Inc = −33.8°, K = 33.3. α 95 = 8.0°). The paleolatitude along which rocks of the block were forming in the Early Cretaceous was defined by the direction of this component (paleolatitude 18°N ± 5°N) as well as coordinates of the paleomagnetic pole (Plat = 18.6°, Plong = 222.4°, with semi-axis of the ellipse of confidence limit dp = 5.2° and dm = 9.1° of the Kiselevka block. The geochemical composition of volcanic rocks in the block suggests that they formed in a within-plate oceanic environment like volcanic rocks of the Hawaii hotspot. Three paleoreconstructions were developed based on the newly received and published data, in accordance with which the Kiselevka block: (1) in the range of 135–105 Ma was moving on the Izanagi plate northwestward at a rate of 15–20 cm/yr up to the eastern edge of Eurasia, thus covering over 5000 km; and (2) in the range of 105–70 Ma was moving northward along the Eurasian transform margin within the accretionary complex fragment at a rate of 4–5 cm/yr to its current position (Lower Amur) as part of the Sikhote-Alin orogen.

Abstract Mesoscopic and microscopic structural analyses of the high-pressure/temperature Sambagawa metamorphic rocks (accretion complexes), SW Japan, have been carried out. Deformation characterized by extreme layer-normal thinning and nearly arc-parallel stretching occurred during exhumation in the Late Cretaceous. Asymmetric quartz c -axis fabrics and orientation of shear band cleavages reveal a pervasive top-to-the-west sense of shear in the Sambagawa metamorphic rocks during the exhumation stage. The 3D strain geometries, inferred from quartz c -axis fabric patterns, vary from plane strain to flattening across the metamorphic belt. We hypothesize that the data are most reasonably explained by a model of counter-flow in the subduction channel. The counter-flow was induced by a left-lateral oblique subduction of the oceanic (Izanagi) plate, which was strongly coupled with the subducting sediments. The 3D strain geometries suggest that the counter-flow (i.e. simple shear in the model) must have been accompanied by some arcnormal ‘press’ component. The mode of deformation changed from ductile to brittle arc-parallel extension, when the rocks were elevated and cooled below the temperature condition for the brittle–ductile transition of quartz ( c. 300 °C). The normal faulting (i.e. brittle extension) at subgreenschist conditions was often accompanied by the precipitation of actinolite. This change in deformation mechanism with decreasing temperature is recorded by a conjugate set of normal faults found in the oligoclase–biotite zone in the study area, for which the palaeostress directions conform to the ductile strain geometries.
