The Neoarchean charnockite of Yinshan Block has been a hot topic into understanding the Precambrian geology of the North China Craton. Although there is a broad consensus that the charnockite is usually related to granulite‐facies metamorphism, its petrogenesis and tectonics still remain controversial. We present a comparative study of the petrography, geochemistry, and geochronology of charnockite...
Voluminous, pyroxene-bearing, intermediate to felsic plutons were emplaced during a 20–50 million year long, spatially extensive Neoarchean igneous event that culminated in the cratonization of North Americaʼs ∼500 km-wide Ungava craton. The crystallization ages of pyroxene-bearing plutons coincide with the emplacement of numerous ca. 2.72–2.70 Ga, Fe-rich, ultramafic/mafic intrusions of the Qullinaaraaluk...
