We present new data for the ∼3.0 Ga Maniitsoq Norite Belt of the Akia Terrane, West Greenland, with the aim of understanding its petrogenesis. The Maniitsoq Norite Belt is hosted in regional tonalite-trondhjemite-granodiorite (TTG) and dioritic ort

The nature and evolution of Earth’s crust during the Hadean and Eoarchean is largely unknown owing to a paucity of material preserved from this period. However, clues may be found in the chemical composition of refractory minerals that initially gr

We investigate the petrogenesis and tectonic significance of corundum (ruby)-bearing late Neoarchean rocks from the Maniitsoq region of southern West Greenland using petrology, thermobarometry, phase equilibrium modelling, and carbon isotopes as well
