Growth of continental crust in intra-oceanic and continental-margin arc systems: Analogs for Archean systems

T Kusky, L Wang - Science China Earth Sciences, 2022 - Springer
Earth's continental crust has grown and been recycled throughout geologic history along
convergent plate margins. The main locus of continental crustal growth is in intra-oceanic …

[HTML][HTML] Stagnant lids and mantle overturns: Implications for Archaean tectonics, magmagenesis, crustal growth, mantle evolution, and the start of plate tectonics

JH Bédard - Geoscience Frontiers, 2018 - Elsevier
The lower plate is the dominant agent in modern convergent margins characterized by
active subduction, as negatively buoyant oceanic lithosphere sinks into the asthenosphere …

Trace element discrimination of arc, slab failure, and A-type granitic rocks

JB Whalen, RS Hildebrand - Lithos, 2019 - Elsevier
Although widely used, classification schemes for granitic rocks have until now failed to
separate slab failure from arc magmatism in collisional orogens. Our previous work showed …

Archean dome-and-basin style structures form during growth and death of intraoceanic and continental margin arcs in accretionary orogens

T Kusky, BF Windley, A Polat, L Wang, W Ning… - Earth-Science …, 2021 - Elsevier
Determining whether plate tectonics or some other mode of planetary dynamics operated in
the early Archean is one of the most contentious and debated areas of Earth Sciences today …

Temporal variations in the incompatible trace element systematics of Archean TTGs: Implications for crustal growth and tectonic processes in the early Earth

P Sotiriou, A Polat, B Windley, T Kusky - Earth-Science Reviews, 2023 - Elsevier
In this study, we applied classification and tectonic setting diagrams, N-MORB-normalised
trace element and incompatible element temporal variation diagrams, Nb/Nb*, Pb/Pb …

Resolving the crustal composition paradox by 3.8 billion years of slab failure magmatism and collisional recycling of continental crust

RS Hildebrand, JB Whalen, SA Bowring - Tectonophysics, 2018 - Elsevier
In the standard paradigm, continental crust is formed mainly by arc magmatism, but because
the compositions of magma rising from the mantle are basaltic and continental crust is …

We present a study based on new and compiled geochronological and geochemical data to
assess the tectonomagmatic evolution of Mexico from the Late Cretaceous and Eocene …

Appinite suites and their genetic relationship with coeval voluminous granitoid batholiths

JB Murphy - International Geology Review, 2020 - Taylor & Francis
Appinite complexes preserve evidence of mantle processes that produce voluminous
granitoid batholiths. These plutonic complexes range from ultramafic to felsic in composition …
