Geodynamic evolution and petrogenesis of the neoarchaean Francistown granite-greenstone complex in NE Botswana, SW margin of the Zimbabwe craton
… the NE Botswana, and with which to formulate a geodynamic model for better understanding of the Archaean crustal growth flanking the southwestern margin of the Zimbabwe Craton

LATERALLY HETEROGENEOUS SEISMIC ANISOTROPY INVESTIGATED BY SHEAR WAVE SPLITTING ANALYSES
… at ~ 250 km and can be explained by a simple geodynamic model invoking absolute plate motion related to simple shear in the lithosphere-asthenosphere transitional layer and mantle flow deflected by the thick lithospheric root of the basin in the upper asthenosphere. In the vicinity of the 2019 …

Dynamic links between short-term deformation and long-term tectonics: a finite element study
… movement. By using 2-D and 3-D finite element models with viscoelastoplastic rheology, I have explored the spatial-temporal strain and stress evolution during seismic cycles, and linked these results to long-term tectonics. In the central Andes, I found that much of the GPS-measured crustal …

Quantifying slab evolution and mantle flow using global subduction models with data assimilation
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-05-01

Metamorphic evolution of ultrahigh-temperature granulite facies and upper amphibolite facies rocks of the Epupa Complex, NW Namibia
… expense of biotite in several paragneisses. In a geodynamic model UHT metamorphism of the Epembe Unit is correlated with the formation of a large magma chamber at the mantle-crust boundary, which forms the source for the anorthosites of the KIC. In contrast, amphibolite facies metamorphism of the …

Studying subduction zone dynamics and continental evolution in South America using data-oriented geodynamic models
… restricted to the sampling area. While numerical modeling can largely overcome these shortcomings, it is affected by uncertain model parameters. As a result, many tectonic questions remain open, with little consensus from decades' of dedicated research. One promising way to further investigate the …

New Constraints For Convergent Margin Plate Tectonic Reconstructions From Imaged And Predicted Mantle Structure
Details of global plate models decrease back in geological time, such that approximately one-third of the Earth surface lacks sufficient plate tectonic constraints by the early Cenozoic ~50 Ma, increasing to >60% uncertainty by the Late Jurassic. The most significant global plate model …
