Abstract Global deep‐time plate motion models have traditionally followed a classical rigid approach, even though deformation is known to be significant. Here we present global Mesozoic–Cenozoic deforming model that captures the progressive extension of all continental margins since initiation rifting within Pangea at ~240 Ma. The also includes major failed rifts and compressional along collision zones. outlines timing regional episodes are reconstructed from wealth published tectonic...
Lateral viscosity variations (LVVs) in the mantle influence geodynamic processes and their surface expressions. With observed long-wavelength geoid, free-air anomaly, gravity gradient three directions discrete, high-accuracy residual topography, we invert for depth- temperature-dependent tectonically regionalized with a flow model. The inversions suggest that gravitational topographic signals are mainly controlled by radial profile; pre-Cambrian lithosphere is slightly (∼ one order of...
Abstract Crustal thickness plays a key role in many geological processes. However, it remains challenging to quantify crustal the past. Here we propose an Extremely Randomized Trees algorithm‐based machine learning model recover of old regions. The is trained using major oxide and trace element compositions 1,480 young intermediate felsic rocks from global arcs collisional orogens geophysical measurements thickness. provides better estimations than commonly used methods based on Sr/Y (La/Yb)...
Abstract Rift basins developed extensively across Sundaland, the continental core of Southeast Asia, since Eocene. Beginning in early Miocene, southern Sundaland experienced widespread synchronous compression (inversion) and marine inundation, despite a large drop long‐term global sea level. The mechanism for this large‐scale regional level rise, basin inversion, subsidence is not well understood contrary to expectations from traditional models eustatic trends. We present geodynamic mantle...
Abstract Accurate reconstruction of paleo‐crustal and lithospheric thicknesses is crucial for understanding the deep geodynamic processes driving uplift growth Tibetan Plateau (TP) their association with Cenozoic magmatism. We reconstruct crustal thickness evolution north‐central TP using a machine learning model intermediate to felsic rocks, estimate based on geobarometers mafic magmas. find that northern Qiangtang terrane (QT) underwent thickening during late Cretaceous‐early Eocene, crust...
Abstract Earthquake moment tensors in eastern Pacific (ePac) slabs typically show downdip tensional (DT) axes, whereas the western (wPac), they compressional (DC) axes or have mixed orientations indicative of unbending. Prevailing conceptual models emphasize uniform stress/deformation modes, that is, bulk slab stretching shortening, as dominant control on intermediate depth seismic expression. In contrast, we propose a diversity expression, including DT‐ and DC‐dominated regions, is...
Abstract The subducted old and cold Pacific Plate beneath the young Philippine Sea at Izu‐Bonin trench over Cenozoic hosts regional deep earthquakes. We investigate slab morphology stress regimes under different motion histories with mantle convection models. Viscosity, temperature, deviatoric are inherently heterogeneous within slab, which we link to occurrence of isolated Models expand on previous suggestions that observed variations along subduction zone, exhibited as shallow dip angles...
Abstract Recycling of crustal material is thought to introduce pyroxenite the peridotite mantle. Mapping such lithological heterogeneity within mantle crucial understanding mantle's chemical evolution but remains challenging. By sampling source, intraplate basaltic melts provide a unique chance reveal We train machine learning (ML) models with major oxide data experimental and help source lithology rocks. The ML can predict lithologies from information an accuracy larger than 94%. As case...
Abstract Dynamic topography, the surface deflection induced by sublithosheric mantle flow, is an important prediction made geodynamic models, but there apparent disparity between model predictions and estimates of residual topography (total minus lithospheric crustal contributions). We generate synthetic global fields with different power spectral slopes spatial patterns to investigate how well long‐wavelength (spherical degrees 1 3) components can be recovered from a discrete set samples...
Abstract Tectonics in North China and adjacent areas were dominated by the Pacific Plate subduction since Jurassic. Although extension‐dominated tectonics Early Cretaceous can be well explained subduction, it is still not understood why underwent intense compression (Yanshanian orogeny) during Late Jurassic these regions rapidly switched to Cretaceous. reconstructions suggest that East Asia was moving direction opposite trench when undergoing strong compressional deformation. This...
Back-arc basins in subduction systems usually form following discrete subduction-related extension stages. However, the westernmost Mediterranean, initiation of Cenozoic associated with Valencia Trough and Algerian Sea Basin introduced two centers nearly simultaneously Gibraltar system, this presents a challenge to understanding their underlying dynamics. We built three-dimensional time-dependent geodynamic models constrained by tectonic reconstructions determine role that played shaping...
Abstract Recent seismic tomography models suggest large‐radius primary plumes originating from the core‐mantle boundary, with grain size variations potentially explaining these observations. Additionally, are thought to enhance long‐term stability of Large Low Shear Velocity Provinces (LLSVPs), identified as thermochemical piles near boundary. Nevertheless, geodynamic investigating hypotheses remain limited. To address this gap, we constructed a series numerical incorporating evolution,...
SUMMARY Mantle convection induces dynamic topography, the lithosphere's surface deflections driven by vertical stresses from sublithospheric mantle convection. Dynamic topography has important influences on a range of geophysical and geological observations. Here, we studied controls Earth's through 3-D spherical models convection, which use reconstructed past 410 Myr global plate motion history as time-dependent mechanical boundary condition. The numerical model assumes extended-Boussinesq...
The Izu-Bonin-Mariana (IBM) subduction zone has one of the most significant advancing trenches on Earth, but mechanism responsible for its trench advance remains in dispute. Slab pull from Ryukyu may have provided main driver this advance. However, it is unclear whether slab-pull force can transmit through weak zones, such as young Shikoku and Parece Vela basins, active Izu-Bonin rifts, continuous spreading Mariana Trough, then act IBM trench. To figure out issue, we conduct slab numerical...
The kinematic reconstruction of the Philippine Sea Plate (PSP) holds significant importance in elucidating Australia−SE Asia collision and Pacific subduction. Previous studies suggested an overall northward motion PSP since its inception, but this first-order model cannot account for observed inconsistencies drift distances among certain sites. Here, we conducted high-resolution Oligocene magnetostratigraphic paleomagnetic research from Deep Drilling Project (DSDP) Site 445, showing that...
Abstract The mechanism behind the significant Izu‐Bonin‐Mariana (IBM) trench advance is still controversial. We conduct slab subduction numerical models that reproduce spatio‐temporal tectonic evolution of Philippine Sea region to investigate whether pull from Ryukyu zone can cross weakened Plate and act on IBM trench. Model results show lithospheric strengthening weakening effects cancel out each other during rift stage so Trench transmit through weak fossil spreading centers intra‐arc...
