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

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
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
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 …

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
