Plate reconstructions since the breakup of Pangaea are mostly based on the preserved spreading history of ocean basins, within absolute reference frames that are constrained by a combination of age‐progressive hotspot tracks and paleomagnetic data. The evolution of destructive plate margins is difficult to constrain from surface observations as much of the evidence has been subducted. Seismic tomography can directly constrain paleotrench locations by imaging subducted lithosphere in the mantle… 

Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction

Teleseismic P-wave imaging of the eastern Caribbean upper mantle is improved and identified subducted-plate fragments are compared with trench locations predicted from plate reconstruction, showing that material at 700–1200 km depth below South America derives from 90–115 Myr old westward subduction, initiated prior to Caribbean Large-Igneous-Province volcanism.

Raising the Resurrection plate from an unfolded-slab plate tectonic reconstruction of northwestern North America since early Cenozoic time

The configuration of mid-ocean ridges subducted below North America prior to Oligocene time is unconstrained by seafloor isochrons and has been primarily inferred from upper-plate geology,

Overview on GPlates: focus on plate reconstruction

extinct spreading Abstract: Plate tectonic reconstructions have been employed in geosciences since 1970s, in the context of hydrocarbon exploration, regional geology and paleobiology. Such studies

Reconstructing Jurassic‐Cretaceous Intra‐Oceanic Subduction Evolution in the Northwestern Panthalassa Ocean Using Ocean Plate Stratigraphy From Hokkaido, Japan

Plate reconstructions of the Panthalassa Ocean typically portray a simple system of diverging plates surrounded by active margins, yet geological and seismic tomographic records demonstrate that

Middle Jurassic to Early Cretaceous tectonic evolution of the western Klamath Mountains and outboard Franciscan assemblages, northern California–southern Oregon, USA

The Klamath Mountains province and adjacent Franciscan subduction complex (northern California–southern Oregon) together contain a world-class archive of subduction-related growth and stabilization

A crucial geologic test of Late Jurassic exotic collision versus endemic re-accretion in the Klamath Mountains Province, western United States, with implications for the assembly of western North America

Differing interpretations of geophysical and geologic data have led to debate regarding continent-scale plate configuration, subduction polarity, and timing of collisional events on the western North

Australian Plate Subduction is Responsible for Northward Motion of the India‐Asia Collision Zone and ∼1,000 km Lateral Migration of the Indian Slab

Distributions of slabs within Earth's mantle are increasingly used to reconstruct past subduction zones, based on first‐order assumptions that slabs sink vertically after slab break‐off, and thus

Initiation of Subduction Beneath the Northeastern Asian Continent in the Late Cretaceous

The Late Albian–Campanian Okhotsk–Chukotka Volcanic Belt (OCVB) extends along the northeastern Asian margin for more than 3000 km. Toward the Pacific, this belt adjoins the microcontinent of the Sea



Intra-oceanic subduction shaped the assembly of Cordilleran North America

This work offers a reinterpretation of North American palaeogeography and test it quantitatively: collision events are clearly recorded by slab geometry, and can be time calibrated and reconciled with plate reconstructions and surface geology.

Two-stage subduction history under North America inferred from multiple-frequency tomography

Eastward subduction of oceanic tectonic plates has shaped the geologic history of western North America over the past 150 million years. The mountain-building and volcanism that brought forth the

Mantle and geological evidence for a Late Jurassic–Cretaceous suture spanning North America

Crustal blocks accreted to North America form two major belts that are separated by a tract of collapsed Jurassic–Cretaceous basins extending from Alaska to Mexico. Evidence of oceanic lithosphere

Mantle provinces under North America from multifrequency P wave tomography

This is a survey of mantle provinces (large‐scale seismic anomalies) under North America, from the surface down to 1500–1800 km depth. The underlying P velocity model was obtained by multifrequency

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

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

Pacific‐Panthalassic Reconstructions: Overview, Errata and the Way Forward

We have devised a new absolute Late Jurassic‐Cretaceous Pacific plate model using a fixed hot spot approach coupled with paleomagnetic data from Pacific large igneous provinces (LIPs) while

Intraoceanic subduction spanned the Pacific in the Late Cretaceous–Paleocene

It is demonstrated that two intraoceanic subduction zones spanned the width of the North Pacific Ocean in Late Cretaceous through Paleocene time and a simple plate tectonic model is presented that explains how they shaped the ~80 to 47 Ma kinematic history of the Pacific realm and drove a major plate reorganization.

How Laramide-Age Hydration of North American Lithosphere by the Farallon Slab Controlled Subsequent Activity in the Western United States

Starting with the Laramide orogeny and continuing through the Cenozoic, the U.S. Cordilleran orogen is unusual for its width, nature of uplift, and style of tectonic and magmatic activity. We present
