- •
The Zhangjiaping pluton in the southern margin of the NCC was emplaced at ca. 1.53 Ga.
- •
These granites show an affinity to fractionated aluminous A-type granites.
- •
They originated from partial melting of the Archean calc-alkaline granitoids.
- •
They were the products of anorogenic magmatism.
- •
Their generation was related to the breakup of the Columbia supercontinent.
