Abstract The extensive fast seismic anomalies in the mantle transition zone beneath East Asia are often interpreted as stagnant Pacific slabs, and a reason for widespread tectonics since Mesozoic. Previous hypotheses their formation mostly emphasize vertical resistances to slab penetration or trench retreat. In this study, we investigate origin of these slabs using global‐scale thermal‐chemical models with data‐assimilation. We find that subduction Izanagi‐Pacific mid‐ocean ridge marked flow...
Abstract The existence of historical flat slabs remains debated. We evaluate past subduction since 200 Ma using global models with data assimilation. By reproducing major Mesozoic whose dip angles satisfy geological constraints, the model suggests a previously unrecognized continental‐scale slab during Late Cretaceous beneath East Asia, result independent plate reconstructions, continental lithospheric thickness, convergence rate, and seafloor age. Tests show that pre‐Cretaceous history,...
The driving force behind the Cenozoic India-Asia collision remains elusive. Using global-scale geodynamic modeling, we find that continuous motion of Indian plate is driven by a prominent upper-mantle flow pushing thick lithospheric root, originated from northward rollover detached Neo-Tethyan slab and sinking slabs below East Asia. maximum mantle drag occurs within strong lithosphere comparable in magnitude to pull (1013 N m−1). cratonic root enhances both lithosphere-asthenosphere coupling...
Abstract At present, there are intensive research efforts towards intermediate temperature solid oxide fuel cells (IT‐SOFCs) with a thin film electrolyte and electrode. In view of the nature molecular level reaction great potential CVD processes for IT‐SOFCs even Micro‐SOFC fabrication, various novel techniques have been developed to prepare multi‐component films multi‐layers related SOFC. this paper, described reviewed possible applications in electrolytes electrodes SOFCs, mainly based on...
Abstract The formation of Lau Basin records an extreme event plate tectonics, with the associated Tonga trench exhibiting fastest retreat in world (16 cm/yr). Yet paleogeographic reconstructions suggest that seafloor spreading only initiated around 6 Ma. This kinematics is difficult to reconcile our present understanding how subduction drives motions. Using numerical models, we propose eastward migration Ridge concurrent explains both narrow width and thickened crust Basin. To match slab...
The Tonga-Kermadec subduction zone exhibits the fastest observed trench retreat (up to 16 cm/yr) and convergence rate 23 near its northern end. However, it a paradox: despite this rapid retreat, Tonga slab maintains relatively steep dip angle (53°) above 400 km. turns flat around km, then steepening again until encountering stagnant segment 670 km discontinuity. Despite significance for understanding dynamics, no existing numerical model has successfully demonstrated how such distinct...
