The Dynamic History of 220 Million Years of Subduction Below Mexico: A Correlation Between Slab Geometry and Overriding Plate Deformation Based on Geology, Paleomagnetism, and Seismic Tomography

Abstract: Global tectonic reconstructions of pre-Cenozoic plate motions rely primarily on paleomagnetic and geological data from the continents, and uncertainties increase significantly with deepening geological time. In attempting to improve such deep-time plate kinematic reconstructions, restoring lost oceanic plates through the use of geological and seismic tomographical evidence for past subduction is key. The North American Cordillera holds a record of subduction of oceanic plates that composed the northeastern Pan… Show more

“…The reconstructed “fringing‐arc” system which rifted away from a continental margin and re‐accreted later is not exceptional or unique in the Panthalassa realm. Other examples are found in the deformed circum‐Pacific continental margins of for example, Mexico (the Guerrero arc and Arperos back‐arc basin Boschman, Garza, et al., 2018, Boschman, van Hinsbergen, et al., 2018; Martini et al., 2011) or western Canada (the Wrangellia superterrane Nokleberg, 2000). The timing of opening of the proposed back‐arc basin, as well as its lateral extent, is yet to be determined.…”

“…This scenario is based on the premise that the closure of the Arperos back‐arc basin is diachronous from north to south (Martini et al, ). Likewise, the paleomagnetic study of Boschman et al () in the southern Guerrero Terrane shows two counterclockwise rotations of ~13.0° and ~36.4° during Aptian‐Albian time (120 Ma and 110 Ma; GAPWaP), which correspond to the diachronous closure of the Arperos back‐arc basin. The previous scenario assumes that the Guerrero Terrane was closer to the northern part of the Chortís block, while this scenario does not rule out the possibility of an extension to the south of the tectonostratigraphic terranes of Mexico, or some oceanic crust.…”

“…3B): that the Jurassic continental extensional arc of California, Arizona, and northern Sonora continued southward off the continental margin and formed a fringing oceanic arc, termed the Guerrero-Alisitos-Vizcaino Superterrane (Busby, 2022). This arc formed above a single east-dipping slab, the Farallon/Cocos slab, which is the longest on the planet and has an interpreted age range of 220-0 Ma (Boschman et al, 2018;Boschman, 2020). The oceanic arc of western Mexico was a very robust arc with numerous large volcanic centers and many plutons.…”
