Hudsonian tectonism in the western Churchill Province of Canada encompassed two periods of granitic plutonism. The Hudson suite plutons represent xenocryst-rich, mainly monzogranitic, near-minimum melts emplaced near their source region in thickened

Paleoproterozoic igneous rocks in the Archean hinterland of the Paleoproterozoic Trans-Hudson orogen (THO) consist of voluminous late syn-orogenic to post-orogenic monzonite to granite (Hudson granitoids; ≈1850–1810 Ma), and contemporaneous ultra
